Born March 26, 1960 in San Diego, California, Marcus Allen knew from a young age he was a special talent. During neighborhood football games, he was always several steps ahead of everyone else. He preferred playing defensive back and aspired to be like his hero Lem Barney, but he also spent time in his backyard trying to emulate the running style of Browns legend Leroy Kelly. That time paid dividends when Abraham Lincoln High School coaches Vic Player and Roy Reed decided to make Allen a two-way player, starting him at quarterback. Although Allen was recruited to the University of Southern California to play safety, head coach John Robinson saw enough to Allen’s rushing ability on tape to move him to running back.

He began his college career as a backup for star tailback Charles White. He excelled in limited action, helping the Trojans win a national title as a freshman. The following year, in an effort to maximize the talent on the field, running backs coach John Jackson moved Allen to the fullback position, where he would block for White, as well as have more opportunities to carry the ball. Allen proved to be a proficient and determined blocker, helping pave the way for White to gain 1,803 rushing yards and take home the Heisman Trophy in 1979.

When Allen finally got his chance to carry the load as the team’s primary starter, he proved himself one of the best backs in the nation. He gained 1,794 yards and scored 15 touchdowns as a junior, but that was just a preview of what the talented tailback could do on the field. As a senior, in 1981, Allen put on a masterful all-around performance. He eclipsed 200 rushing yards in eight of eleven games [1]Treating post-season/bowls separately, as does the Heisman Trust. on his way to becoming the first player to run for over 2,000 yards in a single season. Combined with his contribution as a receiver, Allen led the nation with 2,559 yards [2]He added an additional 124 yards in a Rose Bowl loss to Penn State. and 23 touchdowns, earning the Heisman Trophy in the process. [3]He also took home the Maxwell Award and the Walter Camp Award.

Following a decorated career at USC, Allen was drafted tenth overall to the Los Angeles Raiders in the 1982 NFL Draft. Amidst a tumultuous season in which a players strike reduced the schedule to just nine games, the 22 year old rookie thrived. He started strong, picking up 180 yards and a touchdown in his first ever game as a pro. He built on that success and, ultimately, led the league in both yards and scoring while helping the Raiders to an NFL-best 8-1 record. Despite suffering an upset loss to the Jets in the divisional round of the playoffs, Raiders faithful knew they had found a special talent in Allen.

In his second year, he proved to be a dynamic weapon, picking up 1,604 yards on 266 carries and a career-high 68 receptions. He even completed four of seven passes for 111 yards and three scores. Those were solid numbers, but they weren’t enough to garner Allen as much as a Pro Bowl nod. It was the postseason where he built his legacy. En route to trouncing every team on the Raiders’ schedule, Allen gained 584 yards and scored five touchdowns. This included one of the great highlights in Super Bowl history against the favored Washington juggernaut. After his defense stopped John Riggins on a 4th and 1, Allen drove the final nail in the coffin with the signature run of his storied career: a sure stop for a loss that he turned into a 74 yard touchdown jaunt through the heart of the Washington faithful. He earned the Super Bowl MVP award for his efforts.

The following season, he continued to prove his versatility, gaining 758 receiving yards to complement his 1,168 rushing yards. He also led the league with 18 touchdowns. He then outdid himself just a year later. The 1985 season was Allen’s finest as a pro. He rushed for a league-high 1,759 yards and gained a then-record 2,314 yards from scrimmage. [4]A record he held until Barry Sanders gained 2,358 in 1997. His prolific production behind an unheralded offensive line earned him the Most Valuable Player award from the Associated Press and the Pro Football Writers Association. In winning MVP honors, Allen became the only player in history to win an NCAA National Championship, a Heisman Trophy, a Super Bowl, and be named Super Bowl MVP and a league MVP.

Unfortunately, the success of his MVP performance did not carry over into the following season. After topping 100 yards on the ground in the first two games, Allen suffered a nagging ankle injury that diminished his effectiveness for the rest of the year. He would not gain 100 yards on the ground again that season and, in fact, would only top the century mark in six more games in his career. Although he played in 13 games, he lacked the game-changing ability that once defined him. The low point of the season came in week 13 against the Eagles: driving to set up a game-winning field goal in overtime, Allen lost a fumble that was returned 81 yards to set up a Randall Cunningham touchdown run. Some observed this was the turning point in Allen’s career with the Raiders.

In 1987, a players strike saw one game removed from the league schedule and another three played primarily by replacement players. To the displeasure of Raiders owner Al Davis, Allen never crossed the picket line. When it ended, Allen returned from the strike to contend with Davis signing college football legend and professional baseball player Bo Jackson to play running back during the latter part of the season. Although this initially resulted in a timeshare at halfback, Allen ultimately volunteered to play fullback and use his blocking prowess to clear holes for Jackson. This allowed head coach Tom Flores to fully exploit his talented stable of backs, but it also meant significantly fewer carries for Allen. It was a sign of things to come.

Over the next three seasons, Allen would carry the burden of the team’s rushing attack for the first half of the season, knowing he would have to relinquish the role to a part-time football player for the latter part of the year. He threw key blocks for the younger back, threatened opposing defenses as a receiver, often played injured, and led his team by example in the locker room. Even after Jackson suffered a career-ending hip injury, Davis brought in veterans Roger Craig and Eric Dickerson to take the leading role. It wasn’t until 1993, when he was 33 years old, that he was able to get a fresh start and a starting job for a new team.

After being pursued by Chiefs head coach Marty Schottenheimer, Allen joined fellow veteran expat Joe Montana in Kansas City. He repaid his coach’s faith by playing five more years and scoring 47 more touchdowns, including a league-leading 12 rushing scores in his first year with the team. Although age and injury had taken their toll on Allen’s physical abilities, he maintained the mental toughness and innate ability to play football. Schottenheimer would later say: “If God put one person on this earth to be a professional football player it would have been Marcus Allen… He was the most instinctive, natural football player that I have ever been around.” [5]From A Football Life: Marcus Allen.

By the time he retired at the age of 38, he had played in more games (220) and scored more touchdowns (145) than any running back to that point in history. Some focus solely on his career arc and write him off as a compiler who only produced big numbers because he played for a long time. That is simply not the case. On account of the strike his rookie year, his first four seasons comprised just 57 regular season games. Compared with every player in history through the same number of games, Allen ranks fifth in yards from scrimmage (6942). [6]Behind Eric Dickerson, Edgerrin James, Terrell Davis, and LaDainian Tomlinson. Thanks to injuries, strikes, and Davis’s eccentricity, after those first four years, he never played another full season with a starter’s workload.

His uncanny knack for finding the end zone contributed significantly to his long career. As an elder statesman, he was used as the Chiefs’ primary goal line threat. Even when banished to Davis’s doghouse, Allen still got the nod from coaches in critical situations. Consequently, he was able to pick up 18 of his 123 rushing touchdowns during his last four seasons with the team, despite averaging fewer than eight carries per game over that span. It speaks volumes that coaches were willing to disregard ownership in order to get Allen on the field. But it wasn’t just his coaches who valued him; his teammates thought enough of him to vote him team MVP four times between 1984 and 1988, despite his reduced role as a ball carrier.

Despite missing time and feuding with the owner, Allen remained productive when on the field. He was a talented enough receiver that draft analysts thought he might be switched to wide receiver coming out of college. They were on to something. At the time he retired, Allen ranked 22nd among all players, and first among running backs, with 587 career receptions. He was also the first player ever to rush for over 10,000 yards and gain over 5,000 yards receiving in a career. Twenty years later, only Marshall Faulk and Tiki Barber have joined that club. [7]Only Faulk has more of both.

Allen played a full season’s worth of playoff games. In those 16 games, he had 267 carries for 1,347 yards (5.0 YPC) and 11 touchdowns. He added 53 receptions for 530 yards and two touchdowns. A season of 1,877 yards and 13 touchdowns is even more impressive when you consider that nine of those games came after Allen turned 30.

He also used his quarterback pedigree to benefit his teams in the NFL. Over the course of his career, he completed 12 of 27 passes for 282 yards and six touchdowns. These weren’t typical goal line gadget plays you’d expect to see from a running back; they were largely plays with the same degree of difficulty you’d assign to a quarterback.

That kind of versatility earned him admiration from coaches across the league. In a 1985 article, the Los Angeles Times asked several NFL coaches to rate contemporary running backs. Despite a presumed lack of speed leaving him ranked as the ninth-best pure runner, the panel thought enough of the rest of his game to rank him (tied with Walter Payton) as the best all-around running back.

We’ve established that Allen was a natural runner, punishing blocker, talented receiver, and, when called upon, a decent passer. As important to his legacy as his prodigious on-field accomplishments, however, may be his strength of character.

Davis valued loyalty and reportedly considered Allen’s refusal to cross sides during the strike, as well as his frequent holdouts, as personal betrayals. As an act of retribution, Allen believed, Davis refused to release or trade him, instead preferring to let him sacrifice his body as a 205 pound blocking back. It was rumored that Davis instructed the coaching staff not to play him and even went as far as warning quarterback Jay Schroeder not to look to him on pass plays. Despite knowingly fighting an uphill battle, the star running back didn’t create tension in the locker room and, in fact, was universally respected by his peers.

Even after filing an antitrust suit against the NFL (helping pave the way for unrestricted free agency) and publicly lamenting that Davis robbed him of his prime, his teammates honored him with his fifth Commitment to Excellence Award. He was a steadfastly unselfish teammate, even at the expense of his own legacy, and the guys in the locker room recognized both his resilience and his leadership. To paraphrase Allen: You can’t pretend to be tough; either you are or you aren’t. Both mentally and physically, Marcus Allen was tough. He is also one of the all-time greats.

Just like yesterday, I’m very short on time, so Bryan Frye agreed to help keep the streak alive here by asking me to reproduce his work on the career rushing touchdown kings. What follows is a reproduction of his work here. As always, thanks so much to Bryan for contributing.

***************************

As a lover of football history, I enjoy writing about the evolution of the game and examining statistical achievements from a historical perspective. I’m also fond of looking at the progression of career records, as doing so can often give us a glimpse into the progression of the game itself. I’ve previously written about the history of the passing touchdowns, passing yards, and receptions records. Today, I’ll focus on the storied history of the carer rushing touchdowns record.

The first ever Football Sunday in league history occurred on September 26, 1920. [1]This is in dispute, however, because that game, between the Rock Island Independents and the St. Paul Ideals, only featured one official NFL team – the Independents Rock Island Independents back Eddie Novak scored the first touchdown on a ten yard rush, but that was in the day before official stats. We have to move twelve years from that point till we find a full season with officially recorded stats. Note that, while the NFL does not recognize as official most records prior to 1932, it does recognize touchdowns; whether or not the league is correct in doing so is beyond the scope of this article. My aim is to begin in 1932, but to use the numbers the league recognizes for its first rushing touchdown king, Ernie Nevers. Without further ado…

I’m very short on time, so Bryan Frye agreed to help keep the streak alive here by asking me to reproduce his All-Time 53 Man NFL Roster. What follows is a reproduction of his work here on his all-time 53 man roster. Given that I am short on time, maybe you are long on time (is that how time works?), in which case — get ready for a great read.

******************

Sometimes when I am bored, I make football lists or rosters in my head (what is the all-time Steelers team, what is the current all-NFC South team, what is the all-time Hispanic team, etc.). Of all the whimsical thought experiments in which I have engaged, the one with the most decisions and revisions has been my all time 53 man NFL roster (with coaching staff).

The purpose of building an all time 53 man NFL roster is not to simply pluck the best 53 players out of history. If I did that, I’d end up with an unbalanced roster, with as many as seven quarterbacks. Having seven Hall of Fame passers would be nice, but it’s completely unnecessary. The important thing to me is depth, which means I value versatility from the players on the roster. Yes, Jan Stenerud was a great kicker, but why put him on the team when I can have Gino Cappelletti kick, return kickoffs and punts, take handoffs, and catch passes? You get the idea. I will make exceptions for most starters, but I want most of my backups to contribute in more than one area.

Having read the comments sections in some popular sports sites, I feel that it is necessary to make the following disclaimer: Players will be picked, in large part, based on how they performed in their respective eras. Danny Fortmann was one of the great interior offensive linemen of his generation, but it would be insane to posit that he could be plucked out of 1941 and be a star guard today at 6’0” and 210 pounds. That’s smaller than RG3. [continue reading…]

Guest Post: Bryan Frye on Adjusted Drive Yards

Friend of the program Bryan Frye is back for another guest post. As regular readers know, Bryan operates his own fantastic site, http://www.thegridfe.com. You can view all of Bryan’s guest posts here, and follow him on twitter @LaverneusDingle.


For some time, I have wanted to create a new metric that used elements from Total Adjusted Yards (TAY) in order to quantify a team’s production on each drive. Past work from both Chase and Brian Burke has given us insight into the value of touchdowns, interceptions, fumbles, and first downs, translated into yards. This work has been fundamental in the development of stats like Adjusted Net Yards per Attempt, Adjusted Rushing YardsAdjusted Catch Yards, and TAY.

Those metrics have given us valuable insight regarding statistical measurement of individual player performance. I’ve also used TAY to measure the output of offenses and defenses.

However, I wanted to attach generic values to every way a drive can end. [1]With the exception of kneel down drives to end halves or games, as those don’t demonstrate an offense’s (or defense’s) ability to actually play the game. This is not a rigorous study, and it is meant to be a starting point for future research rather than a conclusive formula to govern the way anyone interprets on-field action.

With that in mind, I’ll briefly cover the generic yardage values for various drive outcomes. [continue reading…]

Today’s post is a follow-up to my recent article on adjusting quarterback stats for schedule length and passing environment. In the original piece, I provided you with single-season stats with various era adjustments made. While my main goal was to glean as much as I could from your opinions, I noticed that some readers also liked looking at the different results based on which adjustments I made. With that in mind, I figured it only made sense to submit the career list as well.

When measuring single seasons, I think value over average is the way to go. However, I believe a lower baseline is in order when looking at entire careers. It seems to me that average play is an overlooked aspect of quarterback evaluation, and guys like Brett Favre or John Elway are significantly underrated by statistical models that compare to league average instead of replacement level. I would say that using a higher threshold shows us who was the most dominant, while using a lower threshold shows us who contributed the most value over an extended period. [continue reading…]

Over at TheGridFe, I just finished the single season portion of my series on the (statistically) greatest regular season quarterback performances in NFL history. I’ve discussed the stats, as they are, which always seem to paint modern quarterbacks in a much better light. I’ve prorated for season length, which can sometimes produce a few curious results. I’ve also applied both hard and soft inflation adjustments to account for the evolution of the position and increase in its usage rate. [1]I also presented TAY/P+ scores, but that’s not particularly relevant to this discussion. Check it out anyway, though. After talking with Adam Steele and agreeing that maybe even the most moderate approach still left seasons like Sid Luckman’s 1943 or Dan Fouts’s 1982 getting far more credit than they probably should. So I went ahead and made an even weaker era adjustment, which I will discuss briefly in this post, to try to mitigate the effects of the original modifications.

My main purpose for writing today isn’t to give you another list of great quarterback seasons, although I will do that as well. My goal is to solicit the opinions of the Football Perspective readers, whom I respect for their thoughtful and reasoned nature. I have two primary questions: [continue reading…]

Guest Post: Bryan Frye on Existential Bridesmaids

As the sickle of death swings ever-closer to your head, and you sit and ponder the meaninglessness of it all, it can be easy to think of all those times you crawled and scratched but still failed to reach the mountaintop. Kurt Vonnegut once mused that many people desperately need to hear the message that they are not alone. I’m here to deliver that message. Here are a bunch of other losers who, like you, gave their all and were found wanting. [1]To be more specific, these are the highest ranking seasons in history, in various categories, that failed to top their own year.

Completed PassesDrew Brees, 2010

In 2010, Drew Brees completed 448 passes, which stands as the fifth highest mark in history. However, Peyton Manning set the all-time record that year, completing 450 passes. Don’t feel bad for Brees. He broke the record the following year and passed Manning’s total again in 2014. [continue reading…]

Recently, I posted a quick and dirty method to measure quarterback career value above average and above replacement. I used Adjusted Yards per Pass Attempt as the foundational stat because its inputs (yards, touchdowns, interceptions, and attempts) are on record back to 1932.

Today, I wanted to use the same model with Adjusted Net Yards per Dropback (ANY/A) as the base metric. I believe ANY/A is a more accurate reflection of quarterback production, but it does have the downside of only being recorded back to 1969 in Pro Football Reference’s database.

Thus, while the previous post covered every passer in the official stat era, this post will only cover value added since 1969. This means greats like Sammy Baugh and Sid Luckman are completely overlooked, while legends like Johnny Unitas and Joe Namath only have their worst years included (an unfortunate byproduct of this study’s limitations, to be sure).

In case you didn’t want to click back through the previous article to see the details of the formula, I’ll briefly cover the basics here: [continue reading…]

Floating around the internet, there are copious metrics for measuring quarterback performance. Some are very basic (passing yards, completion rate), while others are quite complex (EPA, WPA). Some are open-source (passer rating, ANY/A), while others are proprietary (DVOA, Total QBR). It seems there is a stat to cover just about every aspect of QB play, so the last thing we need is another useless number.

Well, I didn’t get that memo.

Today, I’m going to look at a somewhat abstract measurement for career value, based on adjusted yards per attempt relative to league average. I prefer ANY/A and my own TAY/P (and the different iterations of both metrics), but gaps in the record books mean we can only go so far with either. [1]Pro-Football-Reference doesn’t have ANY/A prior to 1969. I don’t have TAY/P prior to 1991; even without including first down data, I can only go back to 1963 before I run out of complete sack … Continue reading With AY/A, we can go back to 1932, the very first season of the “official stat” era in the NFL.

The methodology is simple and straightforward. I took Pro Football Reference’s AY/A Index Scores for every quarterback with at least 1500 career pass attempts. If you are familiar with PFR’s advanced passing stats, you know they are based on three seasons’ worth of data (years n-1, n, and n+1), and a score of 100 represents league average output. [2]Except in 1932, when there is no year n-1, and the current year, when there is no n+1. To find the AY/A+ score itself, you simply multiply a player’s z-score by fifteen and add the product to 100. Using this knowledge, I reverse engineered the passing Index Scores in order to find the number of standard deviations above or below average each quarterback’s AY/A was. I then multiply that number by pass attempts to come up with an abstract career value metric. I also did this for replacement level, using one standard deviation below average as the baseline for replacement play.

The formulas:

Value over average = [(AY/A Index Score – 100)/15]*Attempts

Value over replacement = [(AY/A Index Score – 85)/15]*Attempts

Like I said, this isn’t forking any lightning in the realm of quarterback analysis. It’s just a quick and dirty way to approximate career productivity based on a well-known metric.

The Results

The table below shows the abstract career value of the 182 quarterbacks who met the 1000 attempt threshold. Read it thus: Peyton Manning played 266 career games and had 9380 pass attempts. His career AY/A+ score was 116. This gives him a total value of 10005 above average and 19385 above replacement (this is the metric by which the table is sorted). Note that the table below does list all 182 quarterbacks, but for ease of scrolling, only the top 25 are displayed by default. You can change that using the dropdown arrow on the left, or you can search for your favorite passer.

Oh, and one note: back in 2006, Chase did some back-of-the-envelope calculations that had Rick Mirer as the worst quarterback of all time. 10 years later, not much has changed.

Despite a fourth trip to the Super Bowl, 2015 has been the worst year of Peyton Manning’s storied career. Statistically speaking, he has never been worse, even as a 22 year old rookie starting all sixteen games for a 3-13 team. [1]A team that also went 3-13 the prior year and earned the right to draft him first overall. Relative to league average, Manning produced the worst completion rate, yards per attempt, touchdown rate, interception rate, passer rating, and adjusted net yards per attempt of his career. [2]Using Pro Football Reference’s Advanced Passing Index Scores as my measurement of choice. Manning ranked last among the 36 qualifying passers in Adjusted Net Yards per Attempt. And his normally stellar sack rate also took a hit, with the second worst output of his career (behind only 2001). [3]Of course, being Peyton Manning, he was still better than average; his Sack%+ score was 110 in the regular season.

If we look to advanced metrics to try to uncover some hidden gem about his performance that may be overlooked by standard box score stats, we don’t have much luck. ESPN’s QBR (which only goes back to 2006, mind you) takes into account far more than any other popular metric, and it normally adores Manning. From 2006-2014 (excluding 2011, obviously), Manning ranked 1st, 3rd, 1st, 1st, 1st, 1st, 2nd, and 3rd in Total QBR. [4]Among all quarterbacks with at least 224 action plays. His second place rank in 2013 becomes a first place rank if you finagle the threshold to exclude Josh McCown’s 269 play, 85.2 QBR bout. This year, he ranked 30th with a subpar 45.0 rating.

Football Outsiders’ DVOA and DYAR don’t do Manning any favors either. Not only was 2015 by far the worst season of his career by both metrics, it was also the only below average season of his career. From 1998-2014, his average season was 32.47% better than average by passing DVOA. His worst season by the metric was a 7.70% effort as a doe-eyed rookie. Over that same period, he averaged 1,664 passing DYAR per season, and his average season was worth 2.89 DYAR per pass. [5]Using the average of his averages rather than a weighted average of all DYAR on all pass plays. The point here is to show his average season, not his average performance over the course of his career. This year, Manning was 26.00% below average, as measured by DVOA, and he lost 328 DYAR from his career total. His -0.95 DYAR per play was easily worse than his previous low of 1.18 in his inaugural season.

If the stats aren’t enough, the infamous “eye test” also backs up the belief that this was Manning’s worst-ever season. He struggled to jive with Gary Kubiak’s offense, especially when asked to run bootlegs and throw on the run. His limited power to make pre-snap adjustments, in concert with his decreased mobility, resulted in him taking more abuse in the pocket than he ever had before. [6]I covered this in more detail after his poor week 2 performance. You don’t have to call me a prophet, but I won’t stop you. He threw errant passes and made uncharacteristically poor decisions, causing him to lead the league in interceptions until week 17, despite missing six games. He struggled with nagging injuries, had the worst game of his entire career, and was benched for an inexperienced and marginally talented fourth-year backup. [continue reading…]

Courtesy of Bryan Frye, let’s look at some graphs of the four quarterbacks in the conference championship games. The stat we will be using today is Total Adjusted Yards per Play, which is like ANY/A on steroids.

First, let’s start with Cam Newton. His Total Adjusted Yards per Play is in blue; the average TAY/P allowed by his opponent each week is in black. As you can see, in 6 of 17 games, he was below-expectation, but he’s been above-expectation in five of his last six games. (Note that for each quarterback, the bye week is included, and the division round matchup is plotted below as Week 18.) [continue reading…]

The 2015 regular season is in the books, and all the relevant stats are at our disposal to poke and prod as our hearts desire. Chase already discussed the fact that, statistically, this has been the best passing season in NFL history. League and team passing records fell on a seemingly regular basis, and a few receiving records were in serious jeopardy by season’s end. [1]We probably all know by now that Julio Jones and Antonio Brown became just the third and fourth receivers ever to break the 1,800 yards mark in a single season. It’s also pretty common knowledge … Continue reading [continue reading…]

1 We probably all know by now that Julio Jones and Antonio Brown became just the third and fourth receivers ever to break the 1,800 yards mark in a single season. It’s also pretty common knowledge that the two dynamic receivers also tied for the second most receptions in a single season. However, what you won’t hear in the mainstream is that Jones happened to break one of the more significant single season records when he hauled in his 93rd receiving first down in week 17.

Five weeks of regular season football have come and gone. Those five weeks have seen quarterbacks attempt 5,470 passes and take 5,817 dropbacks. Throw in rushes, and quarterbacks have been involved in 6,184 action plays thus far. [1]Keep in mind this was written before the Thursday night game featuring Matt Ryan and Drew Brees. That seems like a large number, but it is only a fraction of the average 20,764 action plays quarterbacks have been involved in over the last two seasons. [2]Quarterbacks are currently on pace for just over 21,000 plays, which would be the highest total in history by a small margin. There are still 358 games left in the regular season (69.9% of the schedule), and we cannot know with epistemic certainty what is going to happen between now and January 3.

However, it is still fun to take the plays we have seen (and the stats those plays have produced) and use them to assess the quarterback landscape of this young season. The following tables present raw, rate, and adjusted stats for the 35 quarterbacks who have attempted at least 70 passes this season. [3]The NFL official requirement for rate stat qualification. I’ll provide some brief commentary, but I’d like to let Chase’s educated audience come up with their own points. Without further ado, here are the raw stats… [continue reading…]

On Monday, I looked at which quarterbacks since 1960 helped or hurt their teams the most by taking or avoiding sacks. On Tuesday, I looked at the quarterbacks who gained the most or fewest yards through the air per attempt or dropback, and on Wednesday, we looked at completions relative to league average. Yesterday, the metric of the day was touchdown pass rate.

As promised, this article, “Dr. Safelove or: How I Learned to Start Worrying and Fear the Bomb,” centers on interceptions. The methodology here is no different from before: Figure out each player’s rate stats relative to the average of the rest of the league minus that player (LMP) that year and multiply it by his attempts to find the marginal total.

The caveat for this article is a big one: it is mathematically impossible for modern players to rank highly on a per play basis. In 1945, Sammy Baugh threw interceptions at a rate 7.4% lower than his peers. Because the league average today is so low (about 2.5%), a current quarterback would have to throw negative interceptions to match a -7.4% relative pick rate. Even if a quarterback threw 700 passes without an interception, the best he could possibly do is about -2.5%. [continue reading…]

On Tuesday, I looked at the quarterbacks who gained the most or fewest yards through the air per attempt or dropback. And yesterday, we looked at completions relative to league average.

Today’s article, “Mile High Club or: Scoring through the Air,” is an examination of how often quarterbacks threw touchdowns. [1]Note that I didn’t say “how well quarterbacks threw touchdowns.” A screen with 80 YAC, a bomb to a wide open speedster, and a missile into tight coverage all count for six on the stat sheets.

I have used the same methodology as before (similar to Chase’s model for Relative Adjusted Net Yards), and I have maintained the same minimum attempt cutoffs. That means we’ll only look at seasons with 224 or more attempts and careers with 1,000 or more attempts. Like before, I didn’t prorate for shorter seasons. [2]Feel free to copy the table and make your own spreadsheet if you’d like. Or don’t. I’m not going to tell you how to live your life. [continue reading…]

Yesterday, I looked at which quarterbacks since 1960 helped or hurt their teams the most by taking or avoiding sacks. In this post, “Frequent Flyers or: Quarterbacks who Gained Yards through the Air,” I’ll do something similar but with passing yards instead of sacks.

Because we have the necessary passing stats dating back to 1932, I can take this study back nearly three decades further than the previous one. However, I will use Chase’s estimated sack statistics to examine net yards for all post-1960 quarterbacks.

The math is simple: for each player, subtract his individual raw totals from those of every other quarterback in the league to find the league minus player (LMP) Y/A or NY/A. Next, subtract the LMP rates from the individual player rates to find each player’s marginal rate stats. Last, multiply each quarterback’s marginal Y/A by his attempts (or marginal NY/A by his dropbacks) to find marginal yards (or marginal net yards). [1]It took as much time to explain as it did to set up in Excel.

Enough explanation – Let’s look at some stats. The first table displays the 1,563 qualifying QB seasons, sorted by marginal yards. Read it thus: In 2001, Kurt Warner threw 546 passes for 4,830 yards, giving him 8.85 Y/A. The average of the rest of the league was 6.69, so Warner had a marginal Y/A of 2.15. This means his 2001 season is worth 1,176 yards above expectation. [continue reading…]

Last Wednesday, Chase unveiled his estimated sack numbers for 1960-1968. [1]I can neither confirm nor deny that he did this, at least in part, to give Joe Namath some love. I already had this post planned, but I wanted to wait for the estimated stats before running the numbers, as doing so would allow me to go back to 1960 instead of 1969.

This article, “Upright Citizens (Quarterbacks who Avoided Sacks)” is a brief examination of those quarterbacks who saved their teams valuable field position by avoiding sacks. By extension, it is also an examination of those quarterbacks who did the opposite. When Chase presented his 1960-1968 data, he included everyone who threw a pass during that timeframe. Because I am only concerned with quarterbacks, I have removed all non-quarterback plays and recalculated the metrics. [continue reading…]

Last week, I posted a quarterback performance metric that accounts for both passing and rushing. The base stat, Total Adjusted Yards per Play, is easy to comprehend and easy to figure out yourself with basic box score data. My original post only included performance that occurred during or after the 2002 season, because I don’t have spike and kneel data going back further than that. For the sake of consistency, I wanted to maintain the same parameters when calculating career values.

Before we get into the tables, I’d like to first briefly talk about what these numbers are and what they are not.

The formula, in case you forgot: [continue reading…]

I spent a few weeks this offseason parsing out quarterback spike and kneel numbers from post-2002 play by play data. Chase published the findings, which I believe are a useful resource when trying to assess a QB’s stats. [1]For instance, 180 of Peyton Manning’s 303 rush attempts since 2002 have been kneels. He has lost 185 yard on those plays. Why in the world should we include those in his total output? … Continue reading Since I have the data available, I thought it would be good to use it.

Regular readers know Chase uses Adjusted Net Yards per pass Attempt as the primary stat for measuring quarterback performance. [2]It’s not perfect, but it’s at least easy to understand and calculate, and is not proprietary like DVOA, ESPN’s QBR, or PFF’s quarterback grades. I am going to do something similar, but I am going to incorporate rushing contribution as well. This is something Chase talked about doing awhile ago, but we didn’t have the kneel or spike data available. [3]For another thing Chase wrote on combining rushing and passing data — while (gasp) analyzing Tim Tebow — click here. I’ll call the end product Total Adjusted Yards per Play (TAY/P). The formula, for those curious: [4]I use 25 as the modifier for fumbles based on the idea that a QB fumble is worth roughly -50 yards, and fumble recovery is a 50/50 proposition.

[Yards + Touchdowns*20 – Interceptions*45 – Fumbles*25 + First Downs*9] / Plays, where

Yards = pass yards + rush yards – sack yards + yards lost on kneels
Touchdowns = pass touchdowns + rush touchdowns
First Downs = (pass first downs + rush first downs) – touchdowns
Plays = pass attempts + sacks + rush attempts – spikes – kneels [continue reading…]

Similarly, Ben Roethlisberger has spiked the ball 44 times, by far the most in the league since 2002. Why count those 44 “incomplete passes” in his completion rate?

What makes a Hall of Fame player in your opinion? Is it being in some arbitrary percentile grouping at his position? Perhaps it is a combination of stats and memorable moments. How about playoff performance? Maybe you give extra credit for champions. I certainly don’t know, and my personal Hall likely wouldn’t resemble yours. Any of those criteria you prefer, however, calls for an attendant expansion of the Hall of Fame. [1]Thanks to Adam Harstad, who was a great sounding board for my ideas and who probably helped keep this from being twice as long.

Arbitrary Percentile

One criterion people use to determine if a player belongs in the Hall of Fame discussion is his place relative to his contemporaries. If a quarterback or halfback is at or near the top of the league for a good portion of his career, he is almost guaranteed a bust in Canton. [2]The same can’t be said for some positions. I don’t hear many people talking about the legacies of Kevin Williams, Nick Mangold, or Lance Briggs. I’ve heard some analysts argue that the Hall should be reserved for the top 3-5% of players. If the top 3-5% (or any arbitrary percentage you choose) is your cutoff, then it follows that induction class sizes should increase to accommodate the increase in players. The 90th percentile of twelve starting quarterbacks includes one quarterback, whereas the 90th percentile of 32 starting quarterbacks includes three quarterbacks. Since the league has nearly thrice the teams it had fifty years ago, it makes sense to have a concomitant increase in class sizes. [continue reading…]

Guest Post: Remembering Charles Follis

Follis at Wooster High School

Follis at Wooster High School

Fans familiar with the history of the NFL know that Fritz Pollard and Bobby Marshall were the first black NFL players, playing in the league’s inaugural season of 1920. [1]For its first two seasons, the NFL was known as the American Professional Football Association, or APFA. It didn’t become the National Football League until 1922. However, often lost in history is the story of the first recorded black professional football player: Charles Follis.

Follis’ name rarely comes up because he played well before the inception of the NFL, before Americans had even heard of Jim Thorpe. When Follis first played professionally, Pollard was only ten years old, and Marshall was just a freshman at Minnesota. The year was 1904 – when Teddy Roosevelt was more interested in negotiating treaties between Japan and Russia than he was in saving football – and the twenty-five year old “Black Cyclone” inked a meager deal with the Shelby Blues of the Ohio League. However, Follis was more than a footnote in football history, and his story merits another telling.

Follis was born in Virginia in 1879, the oldest of seven children. His father was a farm laborer, which effectively meant Charles was, too. He worked long hours with his father, developing great strength at a young age. [2]This reminds me of the well-known story of Jerry Rice working countless hours with his bricklaying father, catching brick after brick after brick that his father tossed to him. It is unclear when the family left Virginia for Wooster, Ohio, but interviews suggest that it was when Follis was still a small child. [3]From Milt Roberts’ 1975 interview with Follis’ sister-in-law, Florence Follis.

As a junior in high school in 1899, he not only led the effort to establish Wooster High School’s first football team, but he was also subsequently elected team captain by his white teammates. He was the team’s star player as they went undefeated, not allowing a point all season. So great was his impact on Wooster High School that the school’s football stadium was named Follis Field in 1998. His prowess in both football and his best sport, baseball, were so easily recognizable that he was eagerly recruited by the local college. [continue reading…]

Guest Post: Is Reggie Wayne a Hall of Famer?

A future HOFer?

A future HOFer?

Reggie Wayne has been in the news recently because Chuck Pagano called a pair of late-game pass plays in order to stretch Wayne’s streak of consecutive games with at least three receptions to 81 games. [1]That number has since grown to 82. Frankly, I don’t care to criticize either of them for that. What I do want to do is acknowledge an impressive record from a great player and discuss whether or not he is likely to join fellow greats in the Pro Football Hall of Fame. [2]And yes, it is a very impressive streak, regardless of how it was achieved. According to Pro Football Reference, the second longest such streak is Cris Carter’s 58 from 1993-1997.

Hall of Fame voters don’t seem to care too much about advanced stats, so I won’t bother covering anything beyond simple box score numbers. [3]However, if you do want a more in depth look at receiving stats, check out Chase’s series on the greatest wide receivers of all time. What voters do seem to care about are counting stats and a good story, or a combination thereof. Without any more ado, let’s get into the stats and the narrative.

The Stats

Currently ranks 7th all-time in receptions, 8th all-time in receiving yards, and 22nd all-time in receiving touchdowns. I am making the assumption that he will play a few more years at a diminishing level until he retires. That will leave us with a few questions about his statistical merits.

Guest Post: Bryan Frye and Win Contribution Rating

Oh, and Happy Thanksgiving to all the loyal Football Perspective readers!


Win Contribution Rating

It’s Thanksgiving. I don’t have a ton of time to write; you don’t have a ton of time to read. Let’s make this snappy.

A few months ago, I began using a rating that I feel better describes a quarterback’s contributions to helping his team win. I am terrible at coming up with names for stuff like that, but Football Guy Adam Harstad swooped in like a guardian angel and suggested the name “Win Contribution Rating.” I liked it, and I began using it without delay.

I used three metrics that correlate highly with future wins: Brian Burke’s EPA/P, Football Outsiders’ DVOA, and my Adjusted Yards per Play (AYP). [1]Please note that the difference between the 45 yard penalty Chase uses and the 50 yard penalty I use for interceptions is based on this article by Brian Burke. I chose 50 as a compromise between the … Continue reading  The correlation coefficients with future wins (i.e., Year N+1 wins) for the individual metrics are .273 for EPA/P, .265 for DVOA, and .256 for AYP. [2]This includes all quarterbacks for which data is available from both FO and AFA, from 1999-2012. I did not include 2013 because I didn’t know year N + 1 wins; I’m not in the fortune telling … Continue reading When I ran those in a multiple regression, I got the following best fit equation (rounded):

Win% = .5 + EPA/P *.39 + DVOA * .13 + AYP * .008

Because the basis of this regression is win percentage, the equation spits out small decimals that I find aren’t relatable to most of the casual fans I know. To transform this into a number that resembles the NFL passer rating that people already know, I simply multiply by 140 to find the Win Contribution Rating. [3]This may seem strange, but keep in mind that the NFL multiples by 16.67 to achieve its final passer rating.

The highest score since 1999 belongs to Peyton Manning in his virtuoso 2004 performance. Let’s take a look at his rating:

EPA/P: .38
DVOA: 58.9%
AYP: 9.1
WCR = (.5 + .38 * .39 + .589 * .13 + 9.1 * .008) * 140 = 111.7 [continue reading…]

I chose 50 as a compromise between the traditional and the new research. For fumbles, I used the standard 50 yard penalty and divided it in half to account for the randomness of recovery.

Passing Kings, From Friedman to Manning

Friend-of-the-program Bryan Frye has contributed a fantastic guest post for us today. Bryan lives in Yorktown, Virginia, and operates his own great site at http://www.thegridfe.com/, where he focuses on NFL stats and history. Be sure to check out Bryan’s site, and let him know your thoughts on today’s posts in the comments.


Last Sunday, Peyton Manning broke the record for career touchdown passes. You may have heard about it. Rather than add more flotsam and jetsam to the vast sea of internet articles dedicated to Manning, I thought I would instead focus on the rich history of the record itself.

With six weeks behind us, we should be at the point where we can figure out who teams are. [1]For a counter view, see this post by Chase. However, this season seems to be a parity lover’s dream. Although many teams near the poles are who we thought they were, others (such as New Orleans and Dallas and perhaps San Diego) are far from their preseason projections. The middle ranks are a jumble of average and indiscernible teams, and no team was even able to make it to 4-0. [2]Think that’s crazy? In 1961, the Cowboys, Lions, and Eagles were the last undefeated teams in the NFL, at 2-0. With half of the NFL’s teams lingering around 1-2 losses, how can we tell the petty tyrants from those with legitimate claims to the throne? I recently began working on a model to do just that.

Guest Post: Introducing Equivalency Rating

And I thank him for it. Bryan lives in Yorktown, Virginia, and operates his own great site at http://www.thegridfe.com/, where he focuses on NFL stats and history.


In August, I introduced a concept on my site to better adjust the NFL’s passer rating for the league passing environment. I love Pro Football Reference’s use of the Advanced Passing Index for passer rating (Rate+), but it still bothered me that the internal math of the NFL’s formula remained the same.

The NFL’s official passer rating formula is based on four variables: completion percentage, yards per attempt, touchdown percentage, and interception rate. Each of those variables are then used to determine four different variables, as seen below:

A = (Cmp% – .3) * 5
B = (Y/A – 3) * .25
C = TD% * 20
D = 2.375 – Int% * 25

Passer rating is then calculated as follows, provided that each variable is capped at 2.375 and has a floor of zero:

(A + B + C + D)/(0.06)

For each component, a score of 1 represents the ideal average passer. Because the formula is based on a league average completion rate of 50%, modern passers significantly exceed that; pre-modern passers rarely reached it. Similarly, the NFL’s model is based on a 5.5% interception rate and a 5% touchdown rate. Thanks to a Greg Cook injury (and Bill Walsh’s genius reaction to it), those numbers have also changed significantly. Last year, the league interception and touchdown rates were 2.8% and 4.4%, respectively. [continue reading…]

In February, Chase used a regressed version of Football Outsiders’ DVOA metric to derive 2014 expected wins. If you are reading this site, you probably have some familiarity with Football Outsiders and DVOA, FO’s main efficiency statistic. Given the granularity of DVOA, it is no surprise that Year N DVOA correlates more strongly with Year N + 1 wins (correlation coefficient of .39) than Year N wins does (correlation coefficient of .32).

By now, even casual NFL fans probably have at least heard of Pythagorean wins, and regular readers of this site are certainly familiar with the concept. Typically, an analyst uses Pythagorean records to see which teams overachieved and underachieved, which can help us predict next year’s sleepers and paper tigers. Well, I wondered what would happen if we combined the two formulae to make a “DVOA-adjusted Pythagorean Expectation” (or something cooler sounding; you be the judge).

Going back to 1989, the earliest year for DVOA, I used the offensive, defensive, and special teams components of DVOA to adjust the normal input for Pythagorean wins (points). Because DVOA is measured as a percentage, I adjusted the league average points per team game accordingly (I split special teams DVOA between offense and defense). Let’s use Seattle, which led the league in DVOA in 2013, as an example.

In 2013, the league average points per game was 23.4. Last year, Seattle had an offensive DVOA of 9.4% and a defensive DVOA of -25.9% (in Football Outsiders’ world, a negative DVOA is better for defenses).  The Seahawks also had a special teams DVOA of 4.7%.  So to calculate Seattle’s DVOA-adjusted points per game average, we would use the following formula:

23.4 + [23.4 * (9.4% + 4.7%/2)] = 26.15 DVOA-adjusted PPG scored

And to calculate the team’s DVOA-adjusted PPG allowed average, we would perform the following calculation: [continue reading…]
