Brad Oremland is a longtime commenter and a fellow football historian. Brad is also a senior NFL writer at Sports Central. There are few who have given as much thought to the history of quarterbacks and quarterback ranking systems as Brad has over the years. What follows are Brad’s thoughts on a stat-based quarterback ranking system.


I recently concluded an eight-part series on the greatest quarterbacks in the history of professional football. Those rankings were subjective, based on everything I know about the players: stats, awards and honors, coaching and teammates, team success and postseason performance, reputation, the eye test, and so forth.

But I also have a method for classifying quarterbacks statistically. I actually published the results of this formula three months ago, but without revealing the process that produced those results. A number of readers were curious about my methodology, and in this post, I’ll finally explain how the sausage gets made. The math is not complicated — you don’t need a stats background to understand this — but there’s a lot of it: you could calculate most of this with a pencil and paper, but by the end, you’re going to want a spreadsheet.

An alternate uniform for the greatest tight end ever

An alternate uniform for the greatest tight end ever

Over the last three days, we’ve looked at the most dominant fantasy quarterbacks, running backs, and wide receivers. Today, we look at tight ends, using the methodology described over the three previous days.

I am using the following scoring system throughout this series: 1 point per 20 yards passing, 1 point per 10 yards rushing/receiving, 4 points per passing TD, 6 points per rushing/receiving TD, 0.5 points per reception.

You probably expect to see Rob Gronkowski’s 2011 season grade as the best fantasy season by any tight end. But, as it turns out, an AFC West tight end had one season that was ever so slightly more dominant.

You might think I’m talking about Tony Gonzalez, who has an unreal eleven seasons in the top 200. Or Kellen Winslow, who has eight top-200 seasons, half of which rank in the top 25. And if not one of those two, then surely Antonio Gates, who has nine top-200 seasons, including two in the top twenty. Or Shannon Sharpe, of course, who also has nine top-200 seasons, with six of those being in the top 70.

In fact, AFC West teams [1]And we don’t even need to include Seattle, which has 0 entries in the top 200 have 14 of the top 25 seasons by a tight end in fantasy history, and and 19 of the top 35 years. No division has dominated this position like the AFC West, but the best tight end season in fantasy history came from someone else: Oakland’s Todd Christensen. [continue reading…]

The fantasy GOAT

The fantasy GOAT

Yesterday, we looked at the most dominant quarterbacks in fantasy history. Today, the running backs, using the methodology described yesterday. Let’s look at the three best seasons in fantasy history, since all shed light on the formula here. Those three are LaDainian Tomlinson, 2006, which is easy to argue as the best year ever as Tomlinson shattered the record for fantasy points scored. But O.J. Simpson in 1975 (not ’73) was also dominant, and did so in a 14-game season and when the baseline was lower. The darkhorse candidate is Priest Holmes, 2002, who put up insane numbers but missed two games due to injury.

I am using the following scoring system throughout this series: 1 point per 20 yards passing, 1 point per 10 yards rushing/receiving, 4 points per passing TD, 6 points per rushing/receiving TD, 0.5 points per reception.

In 2006, Tomlinson rushed for 1,815 yards with 28 TDs, caught 56 passes for 508 yards and 3 touchdowns, and even threw for 20 yards and two touchdowns. He totaled a still mind-boggling 455.3 fantasy points. On a per game basis, Tomlinson averaged 28.46 FP/G, while the baseline — which for these purposes is RB24 [1]Baselines used in this series: From 1968 to 2014, RB24. In ’66 and ’67, RB20, and from ’61 to ’65, RB16. In the 1960 AFL, the baseline is RB6, while it is RB8 in the NFL. From … Continue reading — was at 10.75 FP/G. Therefore, Tomlinson averaged 17.71 FP/G over the baseline, and he did it for 16 games, giving him a VBD of 283.3 fantasy points (17.71 x 16). [continue reading…]

What was the most dominant fantasy season of all time? You might think Peyton Manning 2013, but let me throw out another candidate: Steve Young, 1998.

I am using the following scoring system throughout this series: 1 point per 20 yards passing, 1 point per 10 yards rushing/receiving, 4 points per passing TD, 6 points per rushing/receiving TD, 0.5 points per reception.

In 2013, Manning threw for 5,477 yards and 55 TDs with just 10 interceptions, while rushing for -31 yards but with one TD. That comes out to 486.75 fantasy points. In 1998, Young threw for 4,170 yards with 36 TDs and 12 INTs, but also ran for 454 yards and 6 TDs. That is equal to 421.90 fantasy points. So, advantage Manning.

But we measure fantasy dominance “not by the number of points he scores[, but] by how much he outscores his peers at his particular position.” Those are the words of Joe Bryant in his famous VBD article, and I’ll make an appendix to that for historical purposes: the key is how much a player outscores his peers at his particular position in that particular year.

When calculating VBD scores, the standard is to use the 12th-ranked quarterback. In 2013, the 12th=-ranked QB scored 309.2 fantasy points, which means Manning outscored him by 177.55 fantasy points (or we could say that Manning produced 178 points of VBD). In 1998, the 12th-ranked quarterback scored just 235.6 fantasy points, which means Young finished with 186.3 points of VBD. So, advantage, Young.

But there’s another piece of the puzzle that tips the scales even more towards the 49ers quarterback. In 1998, Young missed one game. For fantasy purposes, it’s more valuable to have a quarterback produced X points in 15 games than it is for him to produce X points in 16 games, because you can play someone else during that 16th game.

On Sunday, I calculated the average number of pass attempts (including sacks) per game for each season since 1950, and then looked at which were the highest era-adjusted passing games in football history. On Monday, I looked at the single seasons that were the most and least pass-happy, from the perspective of each quarterback and after adjusting for era. Today, career grades.

How much do you know about Frank Tripucka? Probably not that much. If you’re a younger fan, you might know him because Denver “unretired” his #18 when Peyton Manning came to town, or because his son Kelly played in the NBA.

If you’re a Football Perspective regular, you may recall that he was the first quarterback in pro football history to throw for 3,000 yards in a season. [1]And by first, I mean that in the most literal sense: in 1960, Tripucka, playing in the AFL and a 14-game season, crossed the 3,000 yard mark in the final game of the season. For Denver, that … Continue reading Well, after today, you’re never going to forget about Tripucka.

I looked at all quarterbacks who started at least 48 regular season games since 1950. [2]For quarterbacks who played prior to 1950, like Tripucka, they are included, but only their post-1950 stats are counted. As a reminder about the methodology, I then calculated the league average dropbacks per game (i.e., pass attempts + sacks) in each season. Then, I determined the number of dropbacks by each quarterback’s team in each game started by that quarterback.

Then, I compared that number to league average to determine the ratio. Do this for every game of a quarterback’s career, and viola, career ratings! Here’s how to read the table below. Tripucka started 50 games in his career since 1950. In those games, his teams averaged 38.5 dropbacks per game, while the league average was 31 dropbacks. As a result, Tripucka’s teams in games he started finished with 124% as many pass attempts as the average team, or 7.5 more attempts per game. That makes him the most pass-happy quarterback ever. The final column shows whether the quarterback is in, or very likely to wind up in, the Hall of Fame. [3]Note that I have included Peyton Manning, Tom Brady, Drew Brees, Brett Favre, Kurt Warner, and Aaron Rodgers as HOF quarterbacks for these purposes. This is not based on my subjective opinion … Continue reading [continue reading…]

1 And by first, I mean that in the most literal sense: in 1960, Tripucka, playing in the AFL and a 14-game season, crossed the 3,000 yard mark in the final game of the season. For Denver, that happened to be a Saturday. The next day, another AFL quarterback, Jack Kemp, crossed the 3,000-yard threshold with the Chargers. The AFL opened with a 14-game schedule to get a jump on the NFL, which was still playing a 12-game schedule in 1960. The NFL’s regular season ended at the same time, and Johnny Unitas became the first NFL passer to hit 3,000 yards on the same day as Kemp.

This is not based on my subjective opinion of those players, but based on my subjective opinion of their likelihoods of enshrinement.

Yesterday, we looked at which teams had the most pass attempts (including sacks) in individual games relative to league average. Today, we will analyze things on the season level.

Let’s use Tobin Rote as an example. As Brad Oremland noted, Rote was stuck playing for terrible Packers teams in the ’50s that were weak on defense and light at running back. In 1951, Green Bay ranked 12th in the 12-team NFL in rushing attempts, rushing yards, and rushing touchdowns, and 11th in points allowed and yards allowed. The Packers often went with just one running back in the backfield — a rarity in those days — which is a sign that the emphasis on the passing game wasn’t just a result of the team’s losing record. Green Bay also went with a quarterback-by-committee approach: Rote started 11 of 12 games, but he finished the year with 256 pass attempts, while backup Bobby Thomason had 221. Individually, neither had great numbers, but together, they helped Green Bay finish with 50 more pass attempts than any other team in football.

The method I used yesterday, and will be using throughout this series, is to give the starting quarterback credit for all team pass attempts in that game. The reason? If a quarterback gets injured and finishes a game with just 5 attempts, that will kill his average in a misleading way. That would do more harm, I think, than giving him credit for all attempts in the game. But that decision has its drawbacks, and in particular, it seems ill-suited for teams in the early ’50s that employed a QBBC approach. This is particularly relevant here, because “Rote’s” 1951 season checks in as the most pass-happy on our list.

So the Rote line for ’51 should really be thought of as Rote and Thomason. Rote’s 1956 season also makes the top ten, and there’s no fine print necessary there. Rote started 11 of 12 games and threw 308 passes, while Bart Starr started the remaining game and had just 44 attempts that season. The ’56 Packers were not very good, ranking last in both points and yards allowed, and last in rushing attempts, too.

The table below shows the top 300 seasons (minimum 7 games started) in terms of pass attempts relative to league average. You can use the search function to see that Rote’s season in 1954 with Green Bay also makes the cut. To explain what’s in the table below, let’s use season #15 on the list, Shane Matthews in 1999, as an example. That year, Matthews started 7 games, but in those games, the Bears averaged an incredible 47.1 dropbacks per game, the second highest rate ever. Matthews shared some snaps with rookie Cade McNown that year, so you wouldn’t know it just by looking at Matthews’ raw numbers, but the ’99 Bears were insanely pass-happy under Gary Crowton. The league average was 36.3 dropbacks per game, so the Bears in “Matthews games” were 10.8 attempts above average, and 129.8% above league average. [continue reading…]

You remember 1976, don’t you? Two teams — the Colts with Bert Jones and Roger Carr, and the Raiders with Ken Stabler and Cliff Branch — stood out from the pack when it came to pass efficiency that season. The Colts led the NFL in passing yards, ranked 2nd in passing touchdowns, and threw just 10 interceptions, tied for the fewest in the NFL. Oakland threw 33 touchdown passes — nine more than the Colts and 12 more than any other team in football — while ranking 3rd in passing yards. Both teams averaged 7.5 Net Yards per Pass Attempt, while every other team was below seven in that metric. Those two teams went a combined 24-4.

The next four best passing teams were St. Louis, Dallas, Minnesota and Los Angeles. Each of those teams went 10-4 or better. In fact, the linear relationship between pass efficiency and team record was quite strong that year. Take a look at the chart below, which plots Relative ANY/A — i.e., Adjusted Net Yards per Attempt relative to league average — on the X-Axis, and Winning Percentage on the Y-Axis: [continue reading…]

On Saturday, we looked at the top passing performers against each franchise. Yesterday, we did the same thing but with rushing statistics. Today, we revive a post from two years ago and complete the series with a look at the top receiving producers against each franchise (all data beginning in 1960).

Let’s begin with receptions. In the past two seasons, Jason Witten has emerged as the number one franchise nemesis for both Washington and New York, eliminating Art Monk and Michael Irvin, respectively, from the tops of those record books. Witten was already the top guy against the Eagles, making him the career leader in receptions against each of the Cowboys three NFC East rivals.

Other non-surprising news: Jerry Rice is the top man against the Falcons, Saints, and Rams, with his numbers against Atlanta being particularly mind-blowing. Tim Brown is number one against his old AFC West teams, and was also number one against the Seahawks until Larry Fitzgerald just passed him. Andre Reed takes the top spot against the Dolphins/Colts/Jets (Marvin Harrison is #1 against the Patriots), Hines Ward has more catches than anyone against the Browns/Bengals/Ravens, while Cris Carter is number one against all four of his old NFC Norris rivals. [continue reading…]

A couple of years ago on the July 4th holiday, I looked at each team’s franchise nemesis in a number of statistics. Let’s revisit that, beginning today with passing yards and passing touchdowns.

You won’t be surprised to know that John Elway has thrown for more yards against the Chiefs, Chargers, Raiders, and Seahawks — his four division rivals — than any other player has gained against those four teams. Similarly, Dan Marino has thrown for more yards against the Bills, Jets, Patriots, and Colts than any other quarterback. Brett Favre threw for more yards than anyone else against the Lions, Bears, and Vikings (but not the Bucs), and Peyton Manning is the top nemesis for the Oilers/Titans franchise, the Jaguars, and the Texans.

Drew Brees is the big enemy of the Bucs, Panthers, and Falcons, while Ben Roethlisberger is the top passer against the Ravens, Bengals, and Browns. Perhaps more surprising is that Eli Manning has already thrown for more yards against Philadelphia, Washington, and Dallas than any other quarterback: that’s particularly surprising since he wasn’t #1 against any of those teams two years ago.

One that always kind of surprises me is seeing Johnny Unitas as number 1 against the 49ers, but it does make some sense. My guess is you could win quite a few bar bets with that one. Here’s the full list, which includes all passing yards thrown by each quarterback against each of the 32 teams (and includes playoff games): [continue reading…]

Yesterday, I looked at the best defenses in football history in terms of (estimated) points allowed on an (estimated) per drive basis. Today, the reverse: the worst defenses in history, at least, without adjusting for era, in terms of points allowed per drive.

The 1981 Colts take the top spot, and that’s not going to be a surprise to any fan of NFL history. Those Colts teams were terrible, particularly on defense. In ’81, Baltimore beat New England 29-28 in week 1, beat New England 23-21 in the last game of the season, and lost every game in between. In ’82, Baltimore finished 0-8-1. In fact, beginning in December 1980, over the team’s next 31 games, the Colts went 3-1 against the Patriots and 0-26-1 against the rest of the NFL! And beginning in ’81, the Colts went 24 straight games without being favored.

The ’81 Colts finished last in just about every defensive category, including points, yards, turnovers, first downs, passing touchdowns, rushing touchdowns, and net yards per attempt. Baltimore’s defense ranked in the bottom three in both rushing yards and passing yards, too. Baltimore allowed 533 points, which remains the most in a single season in NFL history, undisturbed by the modern era. [continue reading…]

The Purple People Eaters

The Purple People Eaters

The 1969 Minnesota Vikings were really good on defense. It began with the defensive line, as that Minnesota squad was the only team in NFL history to send all four defensive linemen to the Pro Bowl. Alan Page, Carl Eller, Jim Marshall, and Gary Larsen may have been the greatest combination of defensive linemen playing together in their primes in NFL history. The Vikings also had Hall of Fame safety Paul Krause playing in the prime of his career.

Minnesota was quarterback by Joe Kapp, but propped up by the defense: after the season, Kapp was traded to the Patriots, and proceeded to suffer the second worst decline in passer rating in NFL history. The Vikings went 12-2 that season, losing on opening day and in a meaningless game at the end of the year.

Minnesota allowed just 133 points, or 9.5 points per game, in 1969. That’s the 2nd fewest in a season since World War II, trailing only the Gritz Blitz 1977 Falcons. The Vikings allowed 16 touchdowns in 1969, but four came on returns (two on interceptions, one fumble, one interception)! Exclude those, and the Vikings allowed just 84 points on touchdowns and 21 points on field goals, for a total of 105 points allowed to the opposing offense. [continue reading…]

Single-Season Cellar Dwellars in OPPED

On Sunday, I looked at the single-season leaders in estimated offensive points per estimated drive. Today, let’s look at the reverse: the teams since 1950 with the fewest points per estimated drive.

The 1977 Bucs ranked last in the NFL in points, yards, first downs, passing yards, passing touchdowns, net yards per attempt, rushing yards, and rushing yards per carry. The team ranked third from last in rushing touchdowns and interceptions. It was that kind of year for Tampa Bay, as the team was shut out 6 times in 14 games, and held to just a field goal in three others.

Tampa scored just 103 points, but the defense scored four touchdowns! As a result, the Bucs get credit for just 76 estimated offensive points (the offense does get credit for one missed extra point), the fewest of any team since 1950. [continue reading…]

As regular readers know, PFR’s Approximate Value statistic uses Offensive Points Per Estimated Drive (OPPED) as its base statistic. Given the discussion yesterday regarding estimates drives and scoring, I thought it would be useful to provide a list of the single-season leaders since 1950 in this metric.

Let’s use the 2007 Patriots as an example. For modern teams, we have the data available on how many drives each team had, but for historical teams, it’s not so easy. There are two ways we can measure drives for all teams. One is to measure the end of drives. For example, the ’07 Patriots had:

  • 50 passing touchdowns;
  • 9 interceptions;
  • 17 rushing touchdowns;
  • 24 field goal attempts;
  • 45 punts;
  • 6 fumbles lost; and
  • 0 safeties (i.e., the offense was never sacked in the end zone)

That gives us a total of 151 estimated drives. What we’re missing here are drives that end when the clock runs out and turnovers on downs. Unfortunately, that data is simply not out there historically, although it’s probably not all that important (and, at least with respect to the former, those drives arguably should be excluded, anyway).

We can also measure the start of drives.  The ’07 Patriots:

  • Played 16 games, which means 16 times where the team received the ball at the start of each half;
  • Recorded 0 safeties recorded on defense (which would lead to a possession);
  • Allowed 23 passing touchdowns;
  • Forced 19 interceptions;
  • Allowed 7 rushing touchdowns;
  • Faced 14 opponent field goal attempts;
  • Forced 76 punts;
  • Forced and recovered 12 fumbles.
  • In addition, New England also had 3 pick sixes and returned 3 fumbles for touchdowns.  as a result, we need to subtract 6 from our total, since those turnovers did not lead to drives for the offense.

This method of estimating drives isn’t perfect, either, but if we average the two results, hopefully we get something pretty close.  New England’s offense had 161 estimated drives by this metric, giving them an averaged of 156 estimated offensive drives. [1]Note that the Patriots went 15/21 on 4th down attempts that year. FWIW, Football Outsiders has New England with 158 offensive drives.

What about estimated points? That one is relatively simple:

  • Award 7 points for each rushing touchdown or passing touchdown;
  • Award 3 points for each made field goal

There are flaws here, well, but this is probably the best we can do.  By this method, New England had 532 estimated offensive points, and 3.41 OPPED.  That is the most of any team since 1950.  The full list:

The 1972 Detroit Lions Offense

There are lots of ways to measure a team’s offensive production.  But if a drive does not end in a punt or a turnover, it’s probably a pretty good drive.  Last year, the Packers had just 64 possessions end in a punt (51) or turnover (6 interceptions, 7 fumbles lost).  The Raiders led the way with 138 Bad Drives — defined as possessions that ended in a punt or turnover — so this metric passes the sniff test.

Here’s some more positive evidence for this statistic: Since 1970, the team with the fewest Bad Drives was the 2007 Patriots at 60. [1]And excluding 1982.  That New England team was followed by the ’14 Packers, the ’11 Saints (66), the ’06 Colts (67), the ’10 Patriots (68), the ’72 Lions (68), the ’11 Packers (69), and the ’09 Chargers (69. The Colts from ’04 to ’08 were extremely consistent and extremely strong in this metric, with 71 Bad Drives in ’04, 71 in ’05, ’67 in ’06, 71 in ’07, and 70 in ’08. [continue reading…]

In 2008, Jamaal Charles had 67 carries and averaged 5.33 yards per carry. Those 67 carries represent 5% of Charles’ career attempts to date (excluding playoffs). That season, the NFL league average was 4.20 yards per carry, which means Charles was 1.12 (after rounding) YPC above average in 2008, or 1.12 YPC above average on 5% of his career carries.

In ’09, Charles had 190 carries, representing 15% of his career YPC. He averaged 5.89 YPC, and the league average was 4.24, which means Charles was 1.65 YPC above average for 15% of his career carries.

In 2010, those numbers were 230, 18%, 6.38, and 4.21, so Charles was 2.17 YPC above league average on 18% of his career carries.

I performed that analysis for every season of Charles’ career — and every other player in NFL history — to determine each player’s career YPC average relative to league average. The table below shows the 200 running backs (by default, only the top 10 are shown) in pro football history with the most carries. The table is sorted by YPC over league average. Here’s how to read it. Jamaal Charles ranks 1st in YPC over league average. His first year was 2008 and his last year (so far) was 2014. For his career, Charles has 1,249 career rush attempts, which ranks 118th in pro football history. He has 6,856 yards, giving him a 5.49 career YPC average. His “expected” career yards per carry average — based on the league average YPC in each season of his career, weighted by his number of carries — is 4.21. Therefore, Charles has averaged 1.28 YPC above league average for his career, the highest rate in football history. [continue reading…]

Three years ago on Father’s Day, I posted a trivia question about the first quarterback to get to 100 losses. I won’t spoil that for new readers, and older readers have bad memories so you can try your hand at that trivia question again.

Today, a different trivia question: Who was the first quarterback to get to 100 wins?

Unitas was the career record holder for about nine years. Then, on October 1st, 1978, Fran Tarkenton and the Vikings beat the Buccaneers in Tampa Bay. That marked the 119th victory of Tarkenton’s career, breaking the tie with Unitas set one week earlier. Tarkenton would win five more games in ’78, his final season in the NFL.

Tarkenton was the NFL’s winningest quarterback for 18 years. On December 1st, 1996, John Elway and the Broncos crushed the Seahawks, 34-7. In the process, Elway picked up his 125th career victory. When he set the record, Elway held only a narrow lead in the wins department over Dan Marino. But the ’97 and ’98 seasons were good to him, and Elway retired with 148 career wins. Marino played for one more year, but retired one shy, with 147 career wins.

Elway held the record for just over ten years. That was until Brett Favre, in a 35-13 win over the Giants, won his 149th career game.

Favre retired with 186 wins. And right now, Peyton Manning enters the 2015 season with 178 wins. It would be a surprise if Manning doesn’t edge out Favre this season, which would make Favre — at 8 years — the man who held the title of ‘winningest quarterback’ for the shortest amount of time. How long will Manning hold the record? That will depend on Tom Brady, who has 160 wins. Will Brady play long enough to eclipse Manning? Whichever of the two winds up on top will hold the record for the foreseeable future, especially if they extend it out to 200 wins.

The 2014 Cowboys had a lot of continuity on offense. Each of the team’s 11 main starters on offense started at least 11 games. Quarterback Tony Romo started 15 games, while running back DeMarco Murray, wide receivers Dez Bryant and Terrance Williams, and tight end Jason Witten each started 16 games. The sixth non-lineman starter was usually James Hanna who started 12 games, but even that sells the team short. Hanna played in all 16 games, but started only 12; in four other games, Dallas instead started off with either slot receiver Cole Beasley, third-string tight end Gavin Escobar, or fullback Tyler Clutts on the field over a healthy Hanna.

On the offensive line, Tyron Smith, Travis Frederick, and Zack Martin each started 16 games and made the Pro Bowl; left guard Ronald Leary started 15 games, with the most major injury hitting right tackle Doug Free, who missed three games in the middle of the year with a foot injury, and the final two games (and both playoff games) with an ankle injury.

Things were only slightly hairier on defense. In the secondary, safeties Barry Church and J.J. Wilcox started every game, while cornerback Brandon Carr also played the full slate. Orlando Scandrick started the final 14 games of the year at corner after being suspended for the first two games of the year.

On the defensive line, Jeremy Mincey and Nick Hayden started 16 games, Tyrone Crawford started 15, and George Selvie started 13 games (but played in all 16). The most serious injuries came at linebacker: Rolando McClain started 12 games, Anthony Hitchens started 11, and Bruce Carter started 8 games. Of course, Sean Lee also missed the entire season after tearing his ACL in May.

If you sort the Cowboys roster by number of starts, the top 22 players started 318 games, or 14.5 games per play. That, as you might have guessed, was the most of any team last season:

While Dallas looks pretty good in this analysis, it’s far from exceptional historically. [1]This, at least in part, is due to more specialization in today’s games, and teams being more likely to change the starting lineup (going with three receivers or a fullback instead of two tight … Continue reading Since 1978, 185 teams have had their top 22 starters average at least 14.5 starts.

The table below lists the top 56 teams (a 9-way tie at 48 enlarged a top-50 list) by this metric since 1978. I’ve also displayed each team’s winning percentage in Year N and in Year N+1, with Year N being the initial year in question.

As you might suspect, these teams tended to fare better in Year N than they did the following year. While some regression to the mean is expected, these 56 teams had an average winning percentage of 0.640 in Year N, and then 0.519 in Year N+1. This is too general a study from which to conclude much, if anything, about the 2015 Cowboys. It should go without saying that “starts” are not a perfect proxy for “team health” and even if it were, “team health” is not a good proxy for “amount by which a team was helped/harmed by injuries.” But I did find today’s results interesting enough to share.

A key cog, but not the only one, in the GSOT

A key reason, but not the only one, for the GSOT’s success

In 1999, Marshall Faulk set the NFL record for yards from scrimmage in a season with 2,429. That mark still stands as the 2nd best in NFL history, and Faulk was truly dominant that season.

But while Faulk may have been the key cog in the St. Louis machine, he wasn’t the whole machine. St. Louis led the NFL in total yards, and had the most talented offense in the NFL. Faulk accounted for 36.6% of the Rams total offensive output that year, [1]Receiving Yards + Rushing Yards, or Net Passing Yards + Sack Yards Lost + Rushing Yards. a huge number — but not a historically incredible one.

Consider what Maurice Jones-Drew did in 2011. The Jaguars were 5-11, and finished last by a mile in terms of total yards. Yet, somehow, Jones-Drew led the league in rushing with 1,606 yards, and ranked 2nd with 1,980 yards from scrimmage. No other Jaguar came within 1500 yards of Jones-Drew that year! The Jacksonville star was responsible for an incredible 44.2% of the team’s offensive output that season, the 2nd most in NFL history.

Now, what’s more impressive: being responsible for 44.2% of a bad offense, or 36.6% of a dominant one? That’s up to each reader to decide, but today, I wanted to look at workhorse yardage producers. The table below, which is fully sortable and searchable, shows the top 400 players in the statistic “percentage of team’s total yards from scrimmage”: [continue reading…]

In 2014, Julio Jones led the NFL with 31 catches of at least 20+ yards. He also was tied for 3rd with 25 receptions on either 3rd or 4th down that picked up a first down for his team. Those are two pretty different skill sets, but Jones fared well in both areas.

I thought it would be fun to try to see which wide receivers were big outliers in one of those two metrics relative to the other. [1]The original inspiration for this post came from this Mike Tanier article. There were 56 players with at least 10 receptions of at least 20+ yards last season. I ran a simple linear regression using “20+ Yard Receptions” as my input and “1st down receptions on 3rd/4th down” as my output. The best-fit formula was:

1st down receptions on 3rd/4th down = 6.77 + 0.63 * 20+ Yard receptions

Let’s use Jones as an example. With 31 big play catches, he’d be “expected” to pull in 26.3 first downs on either 3rd or 4th down; as noted above, he came pretty close to hitting that exact number.

Then there are players like Washington’s DeSean Jackson. He had 16 “big play catches” last year, which means we’d “project” him to have about 16.8 first down grabs on 3rd/4th down. In reality, he had just five, falling 11.8 catches short of expectation. As it turns out, that’s the most extreme player in that direction from the 2014 season. The narrative meets the numbers: Jackson is a great deep threat, but not a move-the-chains receiver (or, at least, he’s not being used like one).

In the other corner, we have Anquan Boldin. The crafty veteran had 14 receptions of at least 20+ yards, which means we’d expect him to have recorded about 15.6 first down catches on 3rd or 4th down. In reality, he had 27, giving him 11.4 more than expected. That makes him the most extreme “possession receiver” by this methodology.

Yesterday, we looked at the career leaders in yards from scrimmage over “worst starter.” Today, let’s look at the single-season list.

Chris Johnson set the single-season record for yards from scrimmage in 2009, when he totaled an incredible 2,509 yards. But that’s not the record for YFS in a season on a per-game basis. That ranks only third in NFL history, behind O.J. Simpson in 1975 (not his more famous ’73 season) and Priest Holmes in 2002.

Holmes missed two games due to injury that season, while Simpson set his during a 14-game schedule. As it turns out, Simpson — who set the record for rushing yards over “worst starter” in 1973 — is your single-season yards from scrimmage over “worst starter” king based on his work in 1975.

In ’75, the 26th-ranked player in YFS gained 890 yards, while Simpson rushed for 1,817 yards and gained another 426 yards through the air. With a total of 2,243 yards from scrimmage, Simpson therefore gained 1,353 more yards than the “worst starter” or 1,546 more yards once we pro-rate to a 16-game season.

  • Walter Payton and Barry Sanders lead the way with 9 seasons apiece in the top 300, although as you learned yesterday, Payton still has a big edge over Sanders. That’s because of the top 10 seasons by the duo (all in the top 125), 7 came from Payton.
  • O.J. Simpson has two top-5 seasons; no one else has two in the top 15. Jim Brown has three top-25 seasons; no one else has three in the top 40, and Priest Holmes and Marshall Faulk are the only others with three top-50 seasons. Brown is the only player with 4 top-50 seasons; and Eric Dickerson is the only other player with four top-75 seasons. Brown has five top-65 seasons; Payton is the only other player with five top-100 seasons (next is Emmitt Smith, whose fifth best season is all the way down at 154). But that’s when Brown passes the baton to Payton: the Bears legend has six top-100 seasons, which nobody else can match (Brown’s 6th best year was #123).
  • The Texans have four seasons in the top 300, which puts the following in some perspective. The Bengals have just one season — James Brooks, 1986 — in the top 300. Brooks ranked 3rd in yards from scrimmage that season, the only time any Bengal has ever ranked in the top 3 in that category. The Dolphins have just two top-300 seasons: Ricky Williams in ’02 and ’03. In fact, the single-season YFS leaders for Miami is just a really weird-looking list. Tampa Bay also has just two top-300 seasons, and only two times when a player gained 1,650 or more yards from scrimmage.

Last week, we looked at the career leaders in rushing yards over worst starter; today, we use the same methodology but with yards from scrimmage. Let’s use Walter Payton’s 1977 season as an example.

That season, the NFL had 28 teams, and the 28th-ranked player in yards from scrimmage gained 854 yards.  But Payton, in his best season as a pro, rushed for 1,852 yards and picked up another 269 yards through the air, for a total of 2,121 yards from scrimmage.  That gave him 1,267 yards above the baseline of “worst starter.”  But remember, in ’77, the NFL had a 14-game schedule; pro-rate that to 16 games, and Peyton is credited with 1,448 yards over the baseline.  That’s the 2nd best season ever by this formula.

While 1977 was by far Payton’s best year, he dominated in this metric for most of his career, posting the 48th, 82nd, 87th, 90th, 94th, 108th, and 157th best seasons. And while Emmitt Smith finally edged past Payton on the career yards from scrimmage last in the final games of his career, Payton has a big edge in this metric because we are removing “junk” seasons. In fact, Payton has a big edge over just about everyone. Nobody forgets about Walter Payton, of course, but I wonder if sometimes his dominance in this metric is overlooked: he led the NFL in YFS in ’77 and ’78, then finished 2nd in the category in ’79. He ranked 3rd in YFS in ’80 and in ’83, ’84, and ’85. Add in a 4th-place finish in ’76 and a 5th-place in ’86, and that gives Payton a whopping 9 finishes in the top 5 in yards from scrimmage.

If we use the methodology described above for every season of a player’s career, we get what I think is a better version of the career yards from scrimmage leaders (at least for running backs) because we are removing junk seasons. Below are the career grades for the top 200 players (note that by default, the table only displays the top 25). I have also listed for each back his career yards from scrimmage and his rank in that category. [continue reading…]

On Friday, I looked at the career rushing leaders in “yards over worst starter.” Today, let’s look at the single-season list.

In 1963, Jim Brown rushed for 1,863 yards in a 14-team NFL. The baseline that year was 541 yards, which represents the 14th highest individual rushing total that year. So Brown exceeded that number by a whopping 1,322 rushing yards. Given that 1963 was a 14-game NFL season, that translates to a pro-rated value of 1,511 yards, the third best ever. The table below shows the top 300 single seasons. [continue reading…]

Last year, DeMarco Murray led the NFL with 1,845 rushing yards. The 32nd-ranked rusher last season rushed for 570 yards, which means Murray rushed for 1,275 yards more than the Nth-ranked rusher, with N representing the number of teams in the NFL. That’s obviously excellent, although not quite the best of all time.

That honor, as regular readers could have guessed, belongs to O.J. Simpson. In 1973, Simpson rushed for an incredible 2,003 yards, while the 26th-ranked rusher in the 26-team NFL rushed for 655 yards. As a result, Simpson is credited with 1,348 yards over the Nth-ranked rusher. Then again, remember that this was a 14-game NFL season; we need to pro-rate that number to 16 games to make for a fairer comparison. That brings Simpson’s season up to +1,540, slightly edging out Adrian Peterson‘s 2012 season (2,097, 564, +1533).

What if we use that methodology for every player during every season of his career? That, to me, is an improvement on just a list of the career rushing leaders, since we don’t give players any benefit for junk seasons. That may be the only thing this list is an improvement on — after all, it is still based on only one statistic — but hey, it’s Friday. Below are the career grades for the top 150 running backs (note that by default, the table only displays the top 25). I have also listed for each back his career rushing yards and his rank in that category. [continue reading…]

Quarterback Rushing Data Since 1950

The 2007 season was the ultimate fantasy of the immobile quarterback lover. No quarterback rushed for 400 yards, after at least one quarterback did so in each of the ten prior seasons. Just as importantly, the top quarterbacks were all pocket passers: Tom Brady, Drew Brees, Tony Romo (only 129 rushing yards that season), Brett Favre, Jon Kitna, Peyton Manning, Matt Hasselbeck, Derek Anderson, Jay Cutler, Kurt Warner, and Eli Manning were the top 12 leaders in passing yards. As a group, those dozen quarterbacks rushed for just 67 yards, led by Cutler’s staggering 205 rushing yards.

But it was only seven years earlier that the mobile quarterback wave was taking the NFL by storm. Six quarterbacks hit the 400-yard rushing mark: Donovan McNabb (629), Rich Gannon (529), Daunte Culpepper (470), Kordell Stewart (436), Jeff Garcia (414), and Steve McNair (403). Of the top ten leaders in passing yards, only Vinny Testaverde and Kerry Collins failed to rush for at least 100 yards, and the top 12 leaders in passing yards rushed for an average of 236 yards.

Since 2012, the mobile quarterback has re-emerged. So how do we test how much each quarterback has run since 1950? Here’s what I did. [continue reading…]

The Jerick McKinnon/Matt Asiata Time Share

Last year, I looked at the unusual running back by committee in Arizona in 2013.  Rashard Mendenhall was the team’s primary back, but he averaged 3.17 YPC that season, while Andre Ellington averaged 5.53 YPC. To measure how “unusual” the split was, I came up with the following methodology: calculate the difference between the YPC of the top two running backs (as measured by carries) on each team, and multiply that difference by the number of carries given to the running back with fewer carries. So for the 2013 Cardinals, the difference between Ellington and Mendenhall in terms of YPC was -2.36; we multiply that by 118 to get a value of -278. For 2014, the most extreme result along this line came in Minnesota.

Matt Asiata had 164 carries for the Vikings but gained just 570 yards, for a 3.48 YPC average. Meanwhile, Jerick McKinnon rushed only 113 times but picked up 538 yards, a 4.76 YPC average. So McKinnon averaged 1.28 more yards per carry than Asiata. Then, we multiply -1.28 by 113, which produces a value of -145, the most extreme of the 32 teams last year.

The reason for this two-step process is that when dealing with backup running backs, you sometimes get small sample sizes. For example, Latavius Murray averaged 5.17 YPC on his 82 carries, but the Raiders split doesn’t count quite as extreme as the Vikings split based on this method.  Also, the Cowboys split would look pretty funky if you didn’t penalize RB2s that had only a handful of carries: [continue reading…]

A quick data dump today. Since 1960, players who record 20+ carries in a game were on the winning side of things 72.7% of the time. Steven Jackson, however, is just 30-31-1 in his 62 games where he has had at least 20 carries. Given that we would “expect” a player to win 45.1 games given 62 games with 20 carries, Jackson’s 30.5 wins falls 14.6 wins shy of expectation. That, perhaps not surprisingly to regular readers, is the worst record relative to expectation among all running backs since 1960.

The table below shows all running backs who had at least 20 games with 20+ carries over the last 55 years, including the postseason. Thurman Thomas is on top of the table because he had 71 games with 20+ carries, and his teams went 63-8 in those games for an incredible 0.887 winning percentage. That gave Thomas 11.4 wins over expectation, the most ever. If you want to sort by a different category (say, win%), you can: the table is fully sortable and searchable. [continue reading…]

Comparables To Ryan Tannehill

In 2012, Ryan Tannehill averaged 5.23 ANY/A, which was 0.70 ANY/A below the league average.

In 2013, Tannehill averaged 5.00 ANY/A, which was 0.87 ANY/A below league average.

In 2014, Tannehill averaged 5.83 ANY/A, which was 0.30 ANY/A below league average.

I thought it would be interesting to look for comparables to Tannehill using just those metrics. I ran a query for all quarterbacks since 1970 who were within a 0.5 ANY/A of Tannehill’s Relative ANY/A in three consecutive seasons: that is, quarterbacks who averaged between -1.20 and -0.20 Relative ANY/A in Year N-2, between -1.37 RANY/A and -0.37 RANY/A in Year N-1, and between -0.80 RANY/A and +0.20 RANY/A in Year N, with a minimum of at least 200 pass attempts in all three seasons.

As it turns out, there were just 12 quarterback seasons that met that criteria, with one quarterback meeting those criteria twice over a four-year span. Making the data set even less helpful, just six of those 12 seasons came by players in their 20s, and even one of those came by an over-the-hill Joey Harrington in his final season at age 29: [continue reading…]

You probably have not given much thought to Ty Law since he retired, and you almost certainly haven’t given much thought to what Law did as a member of the Jets in 2005. But it was a pretty remarkable season.

Law had 10 interceptions that year. That number may not sound like a lot to you — it’s not a record, and we rarely focus on interception totals — but no player has had more than 10 interceptions in a season since 1981. Since Everson Walls of the Cowboys recorded 11 interceptions in 1981, eleven players have intercepted exactly ten passes in a single season. Of those, Law played on the team that faced by far the fewest passes, and he did so in an era where it was very difficult to record interceptions. That’s why, by the metric I’ll describe below, it’s the most impressive interception season in NFL history.

First, I calculated each player’s individual interception rate, defined as his number of interceptions divided by his team’s pass attempts faced. [1]Perhaps in a future version, I will adjust for games missed due to injury. The record here was set in 1946 by Pittsburgh’s Bill Dudley, a former first overall pick. That year, Dudley led the NFL in rushing… and punt return yards… and interceptions! Dudley intercepted 10 passes, while the Steelers faced just 162 pass attempts, giving him an interception on 6.2% of opponent dropbacks. Perhaps most amazing, the Steelers leading receivers each had just ten catches, which means Dudley caught as many passes on defense as any Pittsburgh player did on offense in 1946.

Law’s 10 interceptions came against 463 opponent pass attempts, giving him an interception on 2.2% of opposing pass plays. That remains the highest rate in a single season since Walls picked off a pass on 2.4% of opponent pass plays in 1982. But obviously interception rates have been sharply declining, which is what makes Law’s accomplishment so remarkable. [continue reading…]

Previously on “take away his X [best/worst]” plays:

In April, I noted that you would need to take away Peyton Manning’s best 19 passes in order to bring his stellar Net Yards per Attempt average to below league average. Today, we look at the reverse question: How many of Derek Carr’s worst dropbacks would we need to erase to bring his NY/A above league average? I’ll give you a moment to think about the answer.
