Towards a better understanding of pressure rates and offensive line play

This all got started by an interesting comment by skepticismissurvival on the NFL subreddit, who made an observation that, like most good observations, seems obvious in hindsight: the pressure rate allowed by an offensive line is not a great measure of pass protection because it depends in part on how long their QB holds the ball. There is wide variation in release time, which varied from Alex Smith at 2.38 seconds to Tyrod Taylor at 3.12 seconds in 2016. We should not expect the Chiefs and…

Is there a relationship between passing volume and efficiency?

Arguing on the internet A common argument on the internet (e.g. Twitter, where I spent too much time) is that the efficiency of players like Prescott and Wilson in their rookie seasons (and subsequent seasons, for Wilson) was not impressive because they were not asked to throw the ball as much. Once they are asked to throw more often, the argument goes, we can expect their efficiency to fall off. Here is one of many, many examples: This stat is misleading. Seahawks were ranked 32nd,…

How strong is the relationship between offensive line play and team strength?

In recent years, the Seattle Seahawks have had a notoriously poor offensive line. In the past 5 years, Pro Football Focus (PFF) has ranked their line as 20, 27, 19, 30, and 32 out of the 32 teams in the league. At the same time, the team finished #1 in Football Outsiders’ DVOA metric in 4 of those 5 years, and #9 in the other year. On the other hand, there are the Cleveland Browns, whose line has been a consistent strength of the team.…

Thoughts After Week 10 2015

With 57% of the season in the rear view mirror, here are a few thoughts… A few weeks ago, I went on the Numbers Game Podcast with Matthew Freedman and Kevin Cole. When asked about mid-season MVPs, I named Tom Brady, Andy Dalton, Carson Palmer, and Aaron Rodgers as prime candidates (with a hat tip to Ben Roethlisberger, who has played incredibly when healthy-ish). Well, just a few short weeks later and it is now a two man contest. Sure, Cam Newton manufactures some incredible…

Thoughts After Week 8 2015

I haven’t had time to do much more than update stats recently, so I figured I’d write a little something to prove I’m still alive. Here are some thoughts and statistical curiosities so far this season. Tom Brady is the clear frontrunner for MVP. I don’t think I am going out on a limb when I say that; I’m not even climbing the tree. He’s leading the best team in the league, and he’s doing it with a great set of box scores; voters love…

Offense to Defend the Planet

I’ve been traveling a lot over the past few weeks and haven’t had much time for research and writing, so the history of offense series has been stalled. I apologize for that. I planned on finishing my promised piece on AFL offenses last week, but Matt Waldman of the Rookie Scouting Portfolio unexpectedly invited me to participate in his RSP Writer’s Project. When a man I respect tremendously offers me an opportunity to contribute to his site, I jump at it. So no AFL post…

NFL Champions Under the Original Title Format: Tiebreakers

Earlier this week, I looked at the would-be NFL champions if the league never changed its 1920 rules for awarding titles. There were 74 years in league history that produced an undisputed champion. However, there have been 21 seasons that require some tiebreakers. Tiebreaker Champions Under the Original Title Format The next table shows every year in which at least two teams tied for the league’s best record. They are ordered, left to right, by SRS score. The champions (as explained below) are in bold. In 1941,…

Undisputed NFL Champions Under the Original Title Format

Depending on your perspective, the use of a playoff system to crown a league champion is either a great idea or a terrible idea. If you are of the belief that the title should go to the best team, you may not like the playoffs. After all, the more playoff games a number one seed has to play before the Super Bowl, the lower that team’s chances are of hoisting the Lombardi Trophy at season’s end. Alternatively, you may pull for underdogs and love dramatic…

All Time 53 Man NFL Roster

Sometimes when I am bored, I make football lists or rosters in my head (what is the all-time Steelers team, what is the current all-NFC South team, what is the all-time Hispanic team, etc.). Of all the whimsical thought experiments in which I have engaged, the one with the most decisions and revisions has been my all time 53 man NFL roster (with coaching staff). The purpose of building an all time 53 man NFL roster is not to simply pluck the best 53 players…
