Mike Lombardi Cracks the Code to Winning in the NFL

June 19, 2013 History

Yesterday, Joe Fortenbaugh canonized Mike Lombardi for discovering and emphasizing one of the game’s great hidden stats: the number of rushing attempts plus completions a team has in a game. If you hit 50, you’re in great shape. Fortenbaugh reminds us that Lombardi, whose last team went 2-14, “possesses a vast range of knowledge spanning [...]

Are Air Yards Consistent From Year to Year?

June 17, 2013 Passing

Consider the following example. The Colts gain possession at the 20-yard line. Andrew Luck is in shotgun and throws a strike to Reggie Wayne, who catches it at the 30, runs 15 yards, and gets tackled at the 45-yard line. Luck gets credited with 25 passing yards and Wayne records 25 receiving yards. Wayne is [...]

Fantasy Football: How to Project Receiving Yards (FBG)

June 16, 2013 Fantasy

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 [...]

NFL Average Plays per Team Since 1950

June 8, 2013 History

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 [...]

Analyzing Interceptions: 2000 to 2012

June 3, 2013 History

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 [...]

Fantasy Football: Regression to the Mean (FBG)

June 2, 2013 Fantasy

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 [...]

Fantasy Football: Which QB Stats are Most Repeatable? (FBG)

May 26, 2013 Fantasy

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 [...]

Ranking wide receivers by percentage of team yards

May 25, 2013 Receiving

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 [...]

Fantasy Football: Yearly Trends in VBD (FBG)

May 19, 2013 Fantasy

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 [...]

Tempo in the NFL

May 13, 2013 Statistics

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 [...]

Time spent leading, tied, or trailing

May 12, 2013 Statistics

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 [...]

Game Scripts – The Best Teams of 2012

May 6, 2013 Statistics

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 [...]

Longest streaks without a 100-yard rusher

May 4, 2013 Checkdowns

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 [...]

Forgotten Stars: Hugh Taylor

April 8, 2013 History

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 [...]

[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: [...]

Interceptions are much more likely to be returned for touchdowns now

March 28, 2013 History

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 [...]

A closer look at Danny Amendola

March 27, 2013 Receiving

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 [...]

A look at the best receivers to change teams

March 14, 2013 Checkdowns

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 [...]

The predictive value of target data, part II

February 15, 2013 Fantasy

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 [...]

Analyzing the leaders in targets in 2012

February 12, 2013 Receiving

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. [...]

The predictive value of target data

February 11, 2013 Passing

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 [...]

Does pre-season strength of schedule matter?

February 8, 2013 SRS

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 [...]

Is Joe Flacco elite?

January 22, 2013 History

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 [...]

Checkdowns: Career receiving stats in wins and losses

January 6, 2013 Checkdowns

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 [...]

Examining the seasons of Calvin Johnson and Brandon Marshall in a different light

January 1, 2013 History

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 [...]

Checkdowns: Broncos complete 4th largest improvement ever

December 30, 2012 History

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 [...]

Checkdowns: Career rushing stats in wins and losses

December 30, 2012 History

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 [...]

Seattle’s HFA

As usual, Aaron Schatz provided some interesting information in his weekly DVOA recap.
