Over at Footballguys.com, I look at a different method to project receiving yards.

The number of receiving yards a player produces is the result of a large number of variables. Some of them, like the receiver’s ability, are pretty consistent from year to year. But other factors are less reliable, or less “sticky” from year to year. I thought it would be informative to look at three key variables that impact the number of yards a wide receiver gains and measure how “sticky” they are from year to year. These three variables are:

  • The number of pass attempts by his team;
  • The percentage of his team’s passes that go to him; and
  • The receiver’s average gain on passes that go to him.

We can redefine receiving yards to equal the following equation:

Receiving yards = Receiving Yards/Target x Targets/Team_Pass_Att x Team_Pass_Att.

You’ll notice that Targets and Team Pass Attempts are in both the numerator and denominator of one of the fractions, and they will cancel each other out: that’s why this formula is equivalent to receiving yards.

By breaking out receiving yards into these three variables, we can then examine the stickiness of each one, which should help our Year N+1 projections. Below are the best-fit equations for each of those variables in Year N+1:

Future Pass Attempts = 36 + (450 x Pass_Attempts/Play) + (0.255 x Offensive Plays)

Future Percentage of Targets = 6.2% + 71.3% x Past Percentage of Targets

Future Yards/Target = 5.5 + 0.29 x Past Yards/Targets

I then used those three equations to come up with a starting point for receiving yards projections for 28 wide receivers. You can read the full article here.

NFL Average Plays per Team Since 1950

In light of the Patriots nearly breaking the NFL record for plays, and the promise of up-tempo offenses in Philadelphia (under Chip Kelly) and Denver (Adam Gase), it’s easy to think that the number of plays run per team is about to reach historic levels. But that seems really unlikely.

The graph below shows the number of plays run per team game for each season since 1950. The total number of plays run is in blue for the NFL; I also added the same data for the AFL in red. As you can see, the number of plays per team game has been relatively steady over the last 64 years, but the high-water marks were the early ’50s and most of the 1980s.

In addition to plays run, the graph also shows:

  • The number of rushing plays per team game in green, a number that’s obviously on the decline.
  • The number of completions per team game in black, which has risen as the number of runs has declined.
  • The number of incomplete passes per team game in orange. Incomplete passes stop the clock, so I thought we might see something interesting there. How’s this for trivia: there were 13.5 incomplete passes per team game in 2012, the same number that existed in 1948! While 1948 is off the graph, you can see that the number of incomplete passes per game has been remarkably consistent throughout NFL history. In fact, the average from 1950 to 2012 is 13.5 incompletions per game, and the league average was 13.5 +/- one incompletion in over 80% of the seasons since 1950.
  • The number of sacks per team game is in purple, a number that has also stayed very consistent over time. Only three times since 1950 has the league average been less than two sacks per game or more than three sacks per game.

Throwing deep against Charles Tillman can be hazardous to your passer rating

Throwing deep against Charles Tillman can be hazardous to your passer rating.

Last off-season, I produced an exhaustive analysis of fumble recovery rates. With 13 years of play-by-play data at my disposal, I thought it would be worthwhile to take a closer look at interceptions. You can skip to the results section if you like, but let me start with a few disclaimers.

Interceptions are tricky to analyze. Interception rates are very inconsistent from year to year, so much so that completion percentage alone may be a better predictor of future interception rate than actual interception rate. But putting aside randomness, there are two other big factors that determine interception rates: the score in the game and the length of the throw.

Just about every quarterback will throw more interceptions when his team is trailing in the fourth quarter. Situation plays a huge role in football, and that’s true when it comes to interception rates, too. Similarly, quarterbacks are much more likely to be intercepted on deep passes than short ones. One thing I wanted to look at was how much league-wide interception rates varied over a wide range of circumstances.

Unfortunately, there still is a bit of bias in the data. The best quarterbacks are most likely to be winning and the worst quarterbacks are most likely to be losing. That means to the extent that trailing teams throw more interceptions than leading teams, the results are probably slightly overstated. Still, I think getting a sense of the league baseline over hundreds of thousands of throw — even if not evenly distributed — can be a useful exercise.

The Results

From 2000 to 2012, there were 6,689 interceptions thrown. Here’s the breakdown with respect to the points differential (i.e., points scored minus points allowed) for the offensive team immediately before the interception. For example, teams trailing by more than four touchdowns have thrown 110 interceptions over the last 13 regular seasons. That accounts for 1.6% of all interceptions thrown over that time period:

At Footballguys.com, I explain why fantasy football owners need to understand the concept of regression to the mean. Readers of this blog probably don’t need the long background, but you might enjoy some of the graphs at the end. For example, this is the distribution of yards per carry in Year N and yards per carry in Year N+1:

Over at Footballguys.com, I identified which quarterback statistics are repeatable and which ones are most likely to regress to the mean. I also ran a regression using touchdown length as my input and future touchdowns as my output.

From 1990 to 2011, 188 different quarterbacks started at least 14 games and thrown 300+ passes in one year, and then attempted at least 300 passes for the same team the next season. After analyzing the lengths of each touchdown pass for those quarterbacks, I discovered the following:

  • For every one-yard touchdown pass in Year N, expect 0.70 touchdowns in Year N+1
  • For every two-to-five-yard touchdown pass in Year N, expect 0.56 touchdowns in Year N+2
  • For every six-to-ten-yard touchdown pass in Year N, expect 0.77 touchdowns in Year N+2
  • For every 11-to-20-yard touchdown pass in Year N, expect 0.70 touchdowns in Year N+2
  • For every 21-to-30-yard touchdown pass in Year N, expect 0.22 touchdowns in Year N+2
  • For every 31-to-50-yard touchdown pass in Year N, expect 0.33 touchdowns in Year N+2
  • For every 50+ yard touchdown pass in Year N, expect 0.33 touchdowns in Year N+2

If a team throws touchdowns from inside the red zone, that reveals an offensive philosophy that is good for your fantasy quarterback. On the other hand, 21+ yard touchdowns might make the highlight feels, but are very unpredictable from year to year. What does that mean for 2013?

Bambi shouldered much of the Chargers passing offense.

Bambi shouldered much of the Chargers passing offense.

Seven years ago, Doug wrote this post analyzing wide receivers by team receiving yards. That post was overdue for an update for three reasons: (1) it was written seven years ago; (2) Doug only went back to 1978, while we now can go back to 1932; and (3) I think using Adjusted Catch Yards (which gives receivers 5 additional yards for every reception and 20 additional yards for every touchdown) is better than just using receiving yards.

For every year of every receiver’s career, I computed the percentage of his team’s Adjusted Catch Yards that he accounted for. I then averaged together each receiver’s 6 best six seasons according to that metric, and ignored all wide receivers who have played in fewer than six seasons. The results are listed below for the 161 receivers to hit the 25% mark, along with the six years selected for each receiver. As always, you can use the search box to find your favorite receiver, and the table is sortable, too.

Over at Footballguys.com, I analyzed how the fantasy value of quarterbacks, running backs, wide receivers, and tight ends have changed since 1990. The NFL is a very different beast than it was 23 years ago, but you might be surprised to see what that means for fantasy football. To measure value, I examined the VBD curves for each of the four major positions in fantasy football.

For those unfamiliar with VBD, you can read Joe Bryant’s landmark article here. The guiding principle is that the value of a player is determined not by the number of points he scores but by how much he outscores his peers at his particular position. This means that in a league that starts 12 quarterbacks, each quarterback’s VBD score is the difference between his fantasy points and the fantasy points scored by the 12th best quarterback. The cut-offs at the other positions are 12, 24, and 36, for tight ends, running backs, and wide receivers, respectively.

The NFL in 2013 won’t closely resemble how the league looked in 1990, but what does that mean for fantasy football? To determine that, we need to see if VBD has evolved with the rest of the football statistics. Let’s start with a graph displaying number of fantasy points scored by the last starter at each position since 1990. As you can see, quarterback scoring has risen significantly over the last two decades, and the production of the 12th tight end has nearly doubled over that time period.

Worst Starter Since 1990

Twenty quarterbacks started all sixteen games last season:

Mark Sanchez started 15 games for the Jets, but was benched for the week 16 game against the Chargers.  Carson Palmer (ribs/chest) and Brandon Weeden (shoulder) were each injured in week 16, causing them to sit out week 17 (although Weeden probably could have played if the game meant anything.) In addition, Jay Cutler (concussion) and Robert Griffin III (knee) each missed one — but only one — game due to injury. [1]Griffin was on the injury report twice for head injuries but did not miss a start due to concussions.  As for the other seven teams:

Tempo in the NFL

Gronkowski and Hernandez can rest after they score

Gronkowski and Hernandez can rest after they score.

It’s no secret that Bill Belichick’s Patriots ran an up-tempo offense last year: Tom Brady and crew ran 1,191 offensive plays in 2012, just eight shy of tying the record set by the Drew Bledsoe Patriots in 1994. With versatile players like Aaron Hernandez, Rob Gronkowski, and Danny Woodhead, New England was capable of running out of multiple formations without changing personnel and uses that flexibility to prevent defenses from substituting players based on down and distance. As a result, New England ran 31 more plays than any other team and 101 more plays than any other team that had a positive Game Scripts average. We would expect some teams with negative Game Scripts — especially when they have Matthew Stafford and Andrew Luck — to run a lot of plays late in games as they play catch up, which makes the Patriots’ offensive play numbers even more impressive.

New England ran an offensive play every 24.9 seconds, the highest rate in the league. The Saints were second at 26.1, which makes sense: New Orleans also has an MVP quarterback and versatile weapons at tight end (Jimmy Graham) and running back (Darren Sproles). You might be a little surprised to see Joe Flacco’s Ravens come in at #3 in play tempo, but the Ravens finished in the bottom five last year in time of possession. The Eagles will be running a high-octane offense under Chip Kelly in 2013, but Philadelphia already ranked fourth in tempo last year.

Here’s how to read the table below. In 2012, the Patriots ranked 1st in tempo (i.e., seconds per play). New England had an average Time of Possession of 30:56 and ran 1,191 offensive plays, an average of one play every 24.9 seconds. The Patriots Game Script average was 7.7, and New England ran 21.3% of their plays in the 1st quarter, 24.9% in the 2nd quarter, 27% in the 3rd quarter, 25.8% in the 4th quarter, and 0.9% in overtime.

Time spent leading, tied, or trailing

Tom  Brady thinks playing with the lead is funny

Tom Brady thinks playing with the lead is fun.

Earlier this week, I posted the Game Scripts for each team this season and in each game. After spending the time to calculate the Game Scripts — i.e., the average margin of lead or deficit over the course of every game — it involved minimal extra effort to measure the percentage of time each team spent with the lead, tied, or trailing. So that’s what I’ve done for you today. [1]One note: I’ve noticed I made one minor mistake, which I do not have the energy to spend to fix.

It’s not surprising to see the Patriots #1 in minutes spent with the lead: New England ranked first in Game Scripts score and in points differential. But the #2 team might surprise you. One reason the Vikings were so successful basing their offense around Adrian Peterson was because the team held the lead 59% of the time. You may recall the Vikings week 1 victory against the Jaguars, when Christian Ponder led Minnesota from behind to steal the win; that was an extreme outlier. In the team’s other nine victories, the Vikings held the lead for at least 45 minutes in each game. On the other hand, Minnesota led for less than 25 minutes in all seven of their losses.

The table below shows the percentage of the time each team spent leading, tied, or trailing. I’ve also included their respective ranks in each category.

Game Scripts – The Best Teams of 2012

Last year, I introduced the concepts of Game Scripts. There are 3600 seconds in every game: the Game Script is the average score over each of those 3600 seconds. For reference, you can check out this list of the top single-seasons of all-time.

Did you know that the Patriots ranked 20th in pass/run ratio last year? Without the concept of Game Scripts, we can’t put that in proper context. New England actually ranked second in the league in rush attempts last season, a result based on two factors: the Patriots ran an incredible 1,191 plays last year and on average, the team was winning by over a touchdown in each game.

Here are the 2012 Game Script scores for each team, which represent the average lead held by the team in every second of every regular season game from last year:

As most of you know, I also write for Footballguys.com, what I consider to be the best place around for fantasy football information. If you’re interested in fantasy football or like reading about regression analysis, you can check out my article over at Footballguys on how to derive a better starting point for running back projections:

Most people will use last year’s statistics (or a three-year weighted average) as the starting point for their 2013 projections. From there, fantasy players modify those numbers up or down based on factors such as talent, key off-season changes, player development, risk of injury, etc. But in this article, I’m advocating that you use something besides last year’s numbers as your starting point.

There is a way to improve on last year’s numbers without introducing any subjective reasoning. When you base a player’s fantasy projections off of his fantasy stats from last year, you are implying that all fantasy points are created equally. But that’s not true: a player with 1100 yards and 5 touchdowns is different than a runner with 800 yards and 10 touchdowns.

Fantasy points come from rushing yards, rushing touchdowns, receptions, receiving yards, and receiving touchdowns. Since some of those variables are more consistent year to year than others, your starting fantasy projections should reflect that fact.

The Fine Print: How to Calculate Future Projections

There is a method that allows you to take certain metrics (such as rush attempts and yards per carry) to predict a separate variable (like future rushing yards). It’s called multivariate linear regression. If you’re a regression pro, great. If not, don’t sweat it — I won’t bore you with any details. Here’s the short version: I looked at the 600 running backs to finish in the top 40 in each season from 1997 to 2011. I then eliminated all players who did not play for the same team in the following season. I chose to use per-game statistics (pro-rated to 16 games) instead of year-end results to avoid having injuries complicated the data set (but I have removed from the sample every player who played in fewer than 10 games).

So what did the regression tell us about the five statistics that yield fantasy points? A regression informs you about both the “stickiness” of the projection — i.e., how easy it is to predict the future variable using the statistics we fed into the formula — and the best formula to make those projections. Loosely speaking, the R^2 number below tells us how easy that metric is to predict, and a higher number means that statistic is easier to predict. Without further ado, in ascending order of randomness, from least to most random, here is how to predict 2013 performance for each running back based on his 2012 statistics:

Why do you need to run the ball when you have this guy?

Why do you need to run the ball when you have this guy?

The Packers have gone 43 consecutive regular season games without having a 100-yard rusher. Not coincidentally, Green Bay drafted Alabama’s Eddie Lacy and UCLA’s Johnathan Franklin in the draft last weekend, hoping that one of those players can bolster the team’s rushing attack.

Brandon Jackson rushed for 115 yards in an overtime loss against the Redskins on October 10, 2010. How long ago was that? Washington’s quarterback that day was Donovan McNabb. Two months later, Jackson rushed for 99 yards in a loss in Foxboro, and Ryan Grant had 92 rushing yards in a September victory in Chicago in 2011, but no Packer has hit the century mark in a regular season game since October 10th, 2010. (It’s worth noting that James Starks rushed for 123 yards in a playoff victory against the Eagles in the 2010 playoffs, but NFL game streaks routinely exclude postseason performances.)

The table below lists all teams since 1960 to go at least 32 games without a 100-yard rusher. Here’s how the second row of the table reads: The Washington Redskins went 72 games without a 100-yard rusher. The team’s last 100-yard rusher came in a game on December 17, 1961, and the streak finally ended on September 24, 1967. The player to break the streak was Bobby Mitchell, and you can see the boxscore from that game in the final column.

Forgotten Stars: Hugh Taylor

Bones stretches for a touchdown

Bones stretches for a touchdown.

Only three players in NFL history have been responsible for half of their team’s receiving touchdowns over a six-year period: Don Hutson, Jerry Rice, and Hugh Taylor. You probably don’t know much about Taylor, the Washington Redskins star receiver who played from 1947 to 1954. In his first game in the NFL, he caught 8 passes for 212 yards and 3 touchdowns, giving him the record for receiving yards in a player’s first game that stood until 2003.  In his last game, he caught five passes for 106 yards and three touchdowns.  In between those games, he was a star receiver on one of the worst teams in the NFL.  Despite the short career, Taylor came in at #63 on my list of the best receivers of all time. His most impressive season came in 1952, when he was responsible for 45% of the Redskins’ receiving yards and produced the 52nd-best season ever by a wide receiver.

At 6’4, Taylor was one of the tallest receivers of his era, but at only 194 pounds, he was also very deserving of his nickname: Bones. Taylor made up for his skinny physique with a long stride that enabled him to get behind defenders.  I spoke with T.J. Troup, an NFL historian who has coached wide receivers at the college and high school levels, for his thoughts on Taylor. Troup owns a significant amount of NFL film from the late ’40s and ’50s, making him the perfect source for this subject.  He described Taylor to me as one of the best home-run threats of his day, with a playing style similar to other long-striders like Harlon Hill, Don Maynard, and Lance Alworth. The numbers certainly back that up.

The table below shows all receivers who were responsible for at least 39% of a team’s receiving touchdowns over a six-year period.  Note that several receivers would show up multiple times on this list, so for players like Hutson, I’ve limited them to their single best six-year stretch. Taylor’s stretch from ’49 to ’54 ranks second on the list:

Is Arian Foster declining?

[House-keeping note: I’ve added the Salary Cap Calculator to the gray header tabs at the top of each page, so you can now easily get there no matter what page you’re on at Football Perspective.]

A quick look at Arian Foster‘s statistics over the last three years paints a picture of a player in decline:

Year G Rsh RshYd RTD YPC YPG C/G Rec RecYd YPR TD YScm RRTD
2010*+ 16 327 1616 16 4.9 101.0 20.4 66 604 9.2 2 2220 18
2011* 13 278 1224 10 4.4 94.2 21.4 53 617 11.6 2 1841 12
2012* 16 351 1424 15 4.1 89.0 21.9 40 217 5.4 2 1641 17

 

Foster’s declined in rushing yards per game and yards per carry over the last two years, while his value in the receiving game fell off a cliff in 2012. One could reasonably conclude that Foster simply isn’t the same player he used to be, and that he could drop off even more in 2013.  But while the traditional statistics tell one story, what do the advanced metrics say?

Good bit of trivia from my buddy Scott Kacsmar: there were 71 interceptions returned for touchdowns in 2012, the highest number in NFL history. Another interesting fact about the 2012 season: just 2.6 interceptions were thrown per 100 attempts, the lowest figure in NFL history.

We already know that the league-wide interception rate has been rapidly decreasing for years, but the significant increase in interceptions returned for touchdowns per interception is an under-reported story. Last year was the year of the Pick Six, but the Pick Six rate (INTs returned for touchdowns per interception) has been on the rise for several years. The graph below shows both the interception rate (100*INTs/Att) in blue (and measured against the left vertical axis) and the Pick Six rate (100*INT TDs/INT) in red (and measured against the right vertical axis):

A closer look at Danny Amendola

Amendola in his element

Amendola in his element.

Few get the statheads talking like Danny Amendola. Bill Barnwell wrote a free-agent book on Amendola in March, where he presented Amendola in the best possible light. Barnwell noted that over the last four years, Bradford has completed 66.5% of his passes aimed at Amendola compared to just 56.8% to all other targets. Barnwell further argued that since Amendola was much more productive in St. Louis than Wes Welker was in Miami, there is a good chance Amendola sees a big, Tom Brady-induced spike when he moves to New England, too.

Scott Kacsmar takes a slightly different view. First, the pro-Amendola argument: since 2010, the Rams are 12-15-1 (.446) when Amendola plays and 4-16 (.200) when he is out. Kacsmar also shows that the Rams averaged 18.9 PPG, 5.8 yards per pass attempt, and 312 yards per game, along with a 5.9% sack rate, in games with Amendola, versus averages of just 12.6, 5.6, 296, and 8.1%, respectively, in games that St. Louis played without Amendola. On the negative side, Kacsmar focused on Amendola’s miserable 8.81 yards-per-reception average, the lowest in history by a wide receiver with at least 100 receptions (by a pretty large margin). Another reason not to be impressed with Amendola’s high catch rate is that 29% of his receptions were “failed completions” [1]These are plays where the player fails to gain a minimum percentage of yards towards a first down (45 percent on first down, 60 percent on second down and 100 percent on third/fourth down. according to Kacsmar.

Amendola is a unique player in the same sense that Darren Sproles isn’t a traditional running back or Tim Tebow isn’t a traditional quarterback. Amendola’s a wide receiver, but he doesn’t operate the way wide receivers have for much of NFL history. According to Pro Football Focus, Amendola was in the slot on 85% of his routes over the last four years; that’s an enormous number, as even Wes Welker ran routes out of the slot on “only” 73.8% of his routes over that time period.

Welker won't have any more "rare" drops in New England.

Welker won't have any more 'rare' drops in New England.

The craziness continues, with Wes Welker signing with the Denver Broncos being the big story of day two of the league year. The Patriots responded by signing Danny Amendola, the least surprising move since Brandon Lloyd joined Josh McDaniels in New England last year. Arguably the biggest move so far this week has been Mike Wallace joining Dolphins, while Greg Jennings still seems likely to move on from Green Bay. Throw in Percy Harvin to Seattle and Anquan Boldin to San Francisco, and we’re seeing a lot of movement among the top receivers this year. Which gives me an opportunity to do a quick data dump on the best receivers to ever switch teams.

In some ways, it’s hard to find a comparable receiver to Welker. He’s been so productive for so long that it’s easy to be unimpressed with the 118 catches, 1,354 yards, and six touchdowns he had last year, but no receiver had ever switched teams after catching more than 101 catches in a season. Only two receivers — Muhsin Muhammad and Yancey Thigpen — gained more receiving yards in a season than Welker did in 2012 and then played for a new team the next year.

But Welker’s amazingly unique numbers are a product of playing in a very pass-friendly environment on a team that threw 641 passes last year. To compare players across systems and eras, I came up with a wide receiver ranking system last month. That will allow us to look at the best receivers to switch teams and not just the ones from the last couple of decades. For some perspective, Welker ranked 8th among wide receivers last season, although that’s without any Tom Brady-adjustment.

The table below contains a lot of information. It shows receivers who added over 200 yards of value over average in Year N and then played for a new team in Year N+1. For each player, I’ve listed his old team, his age in Year N, some traditional statistics, the amount of value added by the receiver, and his rank among wide receivers. Then starting in the “N+1 tm” category, we see his new team, his statistics in the new season, how much value he added in Year N+1 and his rank in that season.

The predictive value of target data, part II

On Monday, I argued that target data has some predictive value. I wanted to update that post with a few observations.

Wide Receiver Targets

In the original post, I looked at year-to-year data for all players with at least 500 receiving yards in Year N and at least 8 games played for the same team in Years N and N+1. But it makes more sense to limit the sample to only wide receivers if we want to predict how wide receivers project in the next season.

There are 554 pairs of wide receiver seasons that meet the above criteria. [1]I have again pro-rated all seasons to sixteen games. The best fit formula to project future receptions based on prior receptions and prior targets is:

Year N+1 Receptions = 14.0 + 0.547 * Yr_N_Rec + 0.124 * Yr_N_Tar

The R^2 is 0.39, and while the receptions variable is statistically significant by any measure, the targets variable just barely qualifies (p = 0.044) as such. Still, this tells us that for every 8 additional targets a receiver sees in Year N, we can expect one more reception in Year N+1, holding his number of receptions equal.

If we want to project receiving yards instead of receptions, we get:

Year N+1 Receiving Yards = 180.3 + 0.434 * Yr_N_RecYd + 2.55 * Yr_N_Tar

The R^2 is 0.33, implying a slightly less strong relationships, which makes sense: yards are more variable to large outliers than receptions, so you would expect receiving yards to be slightly harder to predict. Another interesting note: the targets variable here is statistically significant at the p = 0.0003 level, and as expected, the receiving yards variable is statistically significant at all levels. Holding receiving yards equal, a receiver would need an additional 19 targets to increase his projected number of receiving yards by 50, so the practical effect may not be all that large.

Analyzing the leaders in targets in 2012

Reggie Wayne led the NFL in targets last year, but that’s a little misleading since the Colts ranked 6th in pass attempts. As a percentage of team targets, Wayne ranked second in the league, but he was a distant number two to Brandon Marshall, who saw two out of every five Bears passes in 2013.

But that doesn’t make him the best receiver. It was easier for Marshall to receive a high number of targets because the rest of the Chicago supporting cast was weak, so Jay Cutler consistently looked Marshall’s way. Chicago ranked 25th last year in Adjusted Net Yards per Attempt, so essentially we have a player on a bad passing offense receiving a ton of targets. It’s not all that obvious how you compare a player like that to Roddy White, who deserves credit for being in a great passing offense but loses targets because of the presence of Julio Jones and Tony Gonzalez (of course, without them, would Matt Ryan start looking like Jay Cutler?)

I identified the leader in targets for each team, and then calculated the percentage of team targets each leading receiver had in 2012. The table below lists that percentage on the Y-Axis; the X-Axis represents the number of ANY/A that player’s team averaged. Someone like Marshall (represented by the first four letters of his last name and the first two letters of his first name, MarsBr) will therefore be high and to the left, while Randall Cobb is low and to the right:

The predictive value of target data

Demaryius Thomas made the most of his targets in 2012.

Demaryius Thomas made the most of his targets in 2012.

In 2007, Doug Drinen and I wrote a pair of articles discussing our views on targets. I’m working on a wide receiver project this off-season, and a complete discussion of receiving statistics includes a discussion of targets.

Let me start with the prevailing few: targets are important, and if two receivers have the same production on a different number of targets, the one who produced on fewer targets is better/more valuable. Similarly, if all else is equal, the receiver with a higher catch rate — calculated as catches/target — is the better/more valuable one.

There are some problems with the prevailing view. By placing targets in the denominator of a formula, we’re implying that targets are a bad thing, or at a minimum, an opportunity wasted. But targets aren’t like pass attempts. Pro Football Focus has a stat called yards per pass route run, and that actually is the receiver version of yards per pass attempt. [1]Unfortunately, yards per pass route run is not going to help us if we want to grade receivers on a historical basis.

But targets don’t help identify the player who deserves blame: on a random incomplete pass, assume three receivers are running routes, and one of them is targeted. Absent a drop, I have a hard time saying that of the three wide receivers, the targeted one did the worst of the three. If we grade a receiver by his yards per route run, each receiver is equally penalized with one route run on the play; if we grade a receiver by yards per target, the two wide receivers that did not get open are not penalized, while the one that was targeted is penalized. That seems fundamentally wrong to me.

Here’s another problem: In a broad sense, the player with more targets (or percentage of his team’s targets) is in a very real sense a bigger part of his team’s offense. Either he’s open more often, or the quarterback is throwing in his direction even when he’s not open (whether because the coaches call more plays for him or because he’s earned the quarterback’s trust). In any event, the target itself is an indicator of quality, and penalizing a player — which is what you do when you place targets in the denominator — for an event that is highly correlated with quality is not something I’m comfortable doing.

Does pre-season strength of schedule matter?

NFL.com posted an article yesterday looking at the strength of schedule for each team in 2013. We have known each team’s opponents since the end of the regular season, and while the full schedule won’t come out until April, it’s simple to calculate a team’s strength of schedule for 2013. Usually, the media reports this by looking at the win-loss record of each opponent from the prior season. Here are the projected SOSs for each team next season:

Is Joe Flacco elite?

Just a guess, but I think that question will be asked quite a few times over the next couple of weeks. While the inanity of the discussion that usually follows that question is not something I wish to emulate, there’s no particular reason not to take an in-depth look at Flacco’s career. The table below shows Flacco’s performance in six key metrics — all relative to league average (1.00) — for each season of his career:

Flacco career

As you can see, with the exception of his great interception rate — which justifies its own post during this pre-Super Bowl period — Flacco’s career performance has been rather average. His touchdown rate, like those of many quarterbacks, has bounced up and down throughout his career. His sack rate was below average during his first three years, improved significantly in 2011, and landed right at the league average in 2012.

ELITE

That is an elite Fu Manchu.

In the three main statistics — Y/A, NY/A, and ANY/A — Flacco has consistently finished in a tight window around the league average. His ANY/A has been slightly better than his NY/A thanks to that lofty interception rate, but suffice it to say Joe Flacco is, and has been for years, a league average quarterback.

If we look at ESPN’s Total QBR, Flacco ranked 27th as a rookie in 2008, 15th in 2009, and 12th in 2010, signaling a young quarterback improving and on the rise. In 2011, he ranked 14th, perhaps signaling a leveling off, and then this past season, he finished 25th. The positive spin would be that he’s a league-average quarterback, and the negative one (at least prior to this post-season) would have been that he was regressing.

On the other hand, here is how Flacco has performed in the playoffs in each game, as measured by AY/A:

Moss makes turkeys out of the Cowboys

Moss was very good when his teams won.

Last weekend, I looked at career rushing stats in wins and losses, and yesterday, I did the same for quarterbacks. Today we will check out the splits for receivers.

I looked at all games, including playoffs, from 1960 to 2011, for all players with at least 4,000 receiving yards over that time period. The table below lists the following information for each player:

– His first year (or 1960, if he played before 1960) and his last year (or 2011, if still active)
– All the franchises he played for (which you can search for in the search box)
– His number of career wins, and his career receptions, receiving yards, yards per reception, and receiving yards per game in wins
– His number of career losses, and his career receptions, receiving yards, yards per reception, and receiving yards per game in losses

You might be surprised to see Andre Johnson at the top of the list, but his career average should decline the longer he plays; that said, 2012 didn’t drop his numbers. On the flip side, Calvin Johnson moves up into the #2 slot; part of that was due to a great season (although Detroit didn’t get many wins) and part of that was due to Randy Moss slipping. Larry Fitzgerald comes up high on the list for the same reason as both Johnsons, although it’s often easy to forget how great Fitzgerald can be thanks to his current situation.

The table is sorted by receiving yards per game in wins:

Three weeks ago, I set forth the argument that perhaps Calvin Johnson was not even the most productive receiver in his own division. While Megatron racked up the numbers, I argued that you have to account for the situation. The relevant situation here is that the Lions ran an incredible 1,160 plays compared to just 999 for the Bears, and Detroit attempted 740 passes while Chicago threw only 485 times.

When one team throws 255 more passes than the other, I don’t think it’s appropriate to compare the receivers based on their raw receiving yards. One thing we could look at is yards per team attempt. The table below lists the number of team attempts for each wide receiver, his raw receiving statistics, and also his yards per attempt. The table is sorted by yards per team passing attempt. And while it is not relevant when discussing Marshall and Megatron, I have also included a Pro-rated Yards per Attempt column, which pro-rates the number of team attempts for the number of games played by the receiver (this helps Percy Harvin, of course).

Why can't we throw it like the Lions do??

Why can't we throw it like the Lions do??


As it turns out, Calvin Johnson was neither the best Johnson nor the best receiver in his division, at least as measured by this metric. I’m not convinced or even arguing that yards/attempt is the best way to rank receivers, but I do think the statistic represents an improvement on just receiving yards. Since receiving yards are so highly correlated with attempts, some adjustment needs to be made, and I plan on providing more analysis on how to grade wide receivers this off-season.

In 2011, the Broncos scored 309 points and allowed 390 points. Despite being outscored by 81 points, the Tim Tebow express still made it into the post-season. In June, I speculated that the 2012 Broncos might set the record for the largest increase in pass completions in one year, and they did just that on Sunday. They also moved into fourth place on another list.

With 481 points and 289 points allowed, Denver outscored its opponents by 192 points in 2012. Peyton Manning and Von Miller have turned the Broncos into one of the best teams in the league a year after they were one of the worst (at least, as measured by points differential). Denver improving their points differential by a whopping 273 points this year relative to 2011, the fourth largest increase in football history.

Trent Richardson thinks this guy was an average running back in losses.

Trent Richardson thinks this guy was an average running back in losses.

Yesterday, I noted that Adrian Peterson is averaging nearly two more yards per rush in losses than wins. He’s also averaging a nearly identical number of rushing yards per game in wins and losses.

As you’re about to see, that’s pretty rare. We all know that wins are correlated with rushing yards, so it should come as no surprise that running backs generally gain more rushing yards in wins than in losses.

I looked at all games, including playoffs, from 1960 to 2011, for all players with at least 3,000 rushing yards over that time period. The table below lists the following information for each player:

— His first year (or 1960, if he played before 1960) and his last year (or 2011, if still active)
— All the franchises he played for (which you can search for in the search box)
— His number of career wins, and his career rush attempts, rushing yards, rushing yards per carry, and rushing yards per game in wins
— His number of career losses, and his career rush attempts, rushing yards, rushing yards per carry, and rushing yards per game in losses

The table is sorted by rushing yards per game in wins. Again, for players like Jim Brown or Peterson, they are included but only their stats from 1960 to 2011 are shown. The table only shows the top 50 players, but the search feature works for the entire table, which includes 281 players. In addition, you can click on the drop arrow and change the number of rows shown.

As always, the table is fully sortable. If you click twice on the far right column, you see the career leaders in rushing yards per game in losses. You probably aren’t surprised to see Barry Sanders at the top, but the presence of the running back formerly known as Dom Davis up there is a bit surprising. Steven Jackson is one of the few players who have averaged over 70 rushing yards per game in losses, which jives with the sixth post in Football Perspective history. In addition, Jackson (at least through 2011) and LaDainian Tomlinson form an interesting example of Simpson’s Paradox: Jackson has a higher career rushing yards per game average in both wins (93.9 to 89.9) and losses (71.1 to 63.2), while Tomlinson has the higher career average overall (78.6 to 78.3).

Seattle’s HFA

As usual, Aaron Schatz provided some interesting information in his weekly DVOA recap. He was looking into Seattle’s home/road splits, and found that the data support what you already know:

[W]hen you look closer at home-field advantage over a period of several years, almost every team generally has the same home-field advantage, which in DVOA works out to about 8.5% on offense and 8.5% on defense. Teams will see their home-field advantage bounce up and down if you only look at things in eight-game periods that coincide with specific seasons, but if you put together six or seven years of data you are going to end up close to 8.5% difference most of the time. The biggest exception seems to be the four NFC West teams, which over the last decade have enjoyed the four largest home-field advantages in the league. And of those four teams, the biggest exception by far is Seattle.

I don’t doubt that Seattle is a much better team at home than on the road. But here’s the question on my mind today: is Seattle much better at home because, well, they’re much better at home…. or because they simply get more favorable home games than the average team? That might sound like the same thing, but Jason Lisk has done a bunch of research on home field advantage as it relates to climate and distance between the teams.

The table below shows the distance each team has traveled this season. The “road” column represents how many miles the team has traveled when they were the road team while the “home” column shows how many miles their opponents had to travel. Note that I excluded the Patriots/Rams game in London, but instead pro-rated their half-seasons to eight games.

Seattle is the most isolated team in the NFL. Now if an expansion team was place in Vancouver or Portland, my guess is that such a team would fare no worse against Seattle than the Giants do against the Eagles or the Jets against the Patriots. But right now, no one is all that close to the Seahawks:

NFL Map

There are also climate issues at play here. Think of the coldest NFL cities — Green Bay, Chicago, Pittsburgh, Cleveland, Buffalo, New England, Denver, Kansas City. They all play in divisions with other cold-weather teams. Meanwhile, the Seahawks are playing teams from California, Arizona, or Missouri in their division. The climates are significantly different. Climate effects are very real but also very complicated, so that’s best left for another day.

Rankings the kickers, from Tucker to Crosby

Mack Brown knows kicker.

Mack Brown knows kickers.

In the summer of 2009, I wrote a three-part series analyzing every kicker of the last half-century (here are the links to Part I, Part II, Part III). What I did there was analyzed field goal attempts by distance, and then credited a kicker for how many field goals he made over the expected number of successful field goals from each distance.

For example, field goal kickers this year have made 15 of 23 attempts from exactly 50 yards. [1]There is some bias in the data in that only the best distance kickers attempts long field goals, but dealing with that is best left for another day. If we assume that 50-yard kicks are successful 65% of the time, then a made 50-yarder will be worth +0.35 field goals and a missed 50-yarder will be worth -0.65 field goals.

To smooth the data, I used kicks from 2005 to 2011, and I also grouped field goals into four-yard increments. In the off-season, I plan to incorporate stadium, temperature, and other weather effects, but for now, I’ve ignored the (often large) role such elements can play.

The table below shows how many field goals over expectation each kicker made through week 15. I also included a column for extra points, and the final column shows how many points over average each kicker provided, giving them 3 points for each field goal and one point for each extra point over average:

So Justin Tucker and Sebastian Janikowski have been the most valuable kickers this year — no surprise there, although Tucker is far from a household name. The worst two kickers won’t shock anyone who has watched much of the Packers or 49ers this year, as David Akers and especially Mason Crosby have been constant sources of frustration for their fans.

I’ll note that I am counting blocked field goals just like a regular miss. When I previewed the list to my brother, he was surprised to see Folk ranking 32nd, since he only missed five field goals. Well, two of them were blocked; if you removed those (and blamed them on the line instead of a low trajectory), he would be 17th (although in this one, I am only removing blocks for Folk). I’d also note that two of his other 3 misses hit the uprights, so I’m not surprised to see my brother (or any Jets fan) surprised to see Folk 32nd.

What if we look at expected field goals over average by distance?

Greg Zuerlein — or Greg the Leg, Young GZ, or Legatron, if you prefer — has cooled off since his hot start. He’s hit 3 of the successful field goals from 56+ yards this season, but all three came in September. Mason Crosby comes out as the worst kicker, and some have defended him because he’s mostly missed long field goals. While that’s somewhat true, this metric adjusts for distance, so he’s struggling even when you consider the difficulty of the kick.

Crosby is 1 for 8 when attempting field goals from 50+ yards, but the average kicker would have been successful on 4.2 field goals. He’s also missed from 32, 38, 42, 43, and 44 yards, and comes out as the worst kicker in the 43-to-46 range. David Akers tied an NFL record with a 63-yarder this year, but otherwise, he’s had a rough season. He’s missed six field goals from inside of 43 yards.

You’re probably hearing a lot right now about how Matt Schaub is not a primetime player — literally. Schaub and the Texans struggled in embarassing losses on Sunday Night Football to the Packers earlier in the season and on Monday Night Football two days ago to the Patriots. Schaub posted terrible numbers in a defensively-driven 13-6 win over the Jay Cutler/Jason Campbell Bears.

For his career, Schaub is 2-5 (0.286 winning percentage) in night games and 41-31 (0.569) in day games. Among the 24 quarterbacks studied (more on that below), that drop in winning percentage is the largest such decline. You might think this is due to facing better defenses in night games, but that’s not really the case.

Schaub has averaged 7.8 Adjusted Yards per Attempt during day games and 6.0 AY/A during night games; that difference of 1.8 AY/A is the second largest among the twenty-four quarterbacks.

So yes, there is no debate: Schaub has been noticeably worse during night games in his career.

The table below shows all quarterbacks who have started a game this season and that have started at least five night games in their career. The data consist of all games throughout their career in which they were the starter. To make it a little easier to read, I’ve shaded the day and night categories differently:
