The Most Pass-Happy Coaches in NFL History

Yesterday, I looked at the most pass-happy active head coaches and offensive coordinators in the NFL. If you’ve been a loyal reader of my previous posts on Game Scripts, you understand the methodology I’ve used today to grade each coaches. The quick summary is I’ve come up with the term “Game Scripts” to determine the average points margin over each of the 3600 seconds in each game; from there, I also came up with Game Scripts scores for each season.  If you then take each coach’s pass/run ratio, adjust for the league average pass/run ratio, and then adjust for Game Scripts, then you can determine each coach’s passing identity.  I’ve done this for every season since 1940.

The table below lists the 252 coaches I have in my database who have been either a head coach or an offensive coordinator for at least four seasons. I suggest using the search box to find your favorite coaches, but as always, all columns are sortable, too. In the table below, the number of HC/OC seasons includes all seasons, but the games, wins, losses, ties, winning percentage, and wins over .500 columns all include only the coach’s records as a head coach. The Game Script column shows each coach’s average Game Scripts average over each season, while the “P/R” column does the same for pass/run ratio.  The next three columns are all indexes centered around 100. The “SCRIPT” column is the Game Scripts rating, the “PASS” column is the Pass/Run Ratio rating, and the Pass Identity column is a combination of the two columns. (You can read some of the other Game Scripts articles for more explanation).  Based on his time in Green Bay with Aaron Rodgers, Joe Philbin comes in as the most pass-happy coach, but that number seems likely to decline the longer he coaches. George Seifert built his reputation as the defensive coordinator for the 49ers, but having Joe Montana, Steve Young, and Jerry Rice turned him into a pass-friendly coach. As for the next two men on the list, modern NFL fans need no further explanation.

The Schottenheimer Index

Marty checking to make sure the pilot light is out.

Marty inquires as to whether Felix Wright's pilot light is out.

Last week, Neil brought us the latest iteration of the Manning Index, showing which quarterbacks have overachieved in the playoffs relative to expectation (based off of the Vegas line). I’m going to do the same today for coaches. A couple of introductory notes:

Neil described the exact methodology in his quarterbacks post, so I won’t waste time repeating it. However, I wanted to look at coaches over an even longer period, and 1950 sounded like a good cut-off.1 Since we don’t have point-spread data for games from 1950 to 19772, I simply used the projected point spread based on the differential between each team’s SRS ratings and by awarding the home team three points. So for pre-1977 games, coaches are credited with wins over expectation based on the SRS, and for post-1977, for wins over expectation based on the Vegas line. Here are the results.

  1. Note that coaches, like Paul Brown, who coached before 1950 are included, but their pre-1950 stats are not. []
  2. One other piece of fine print: for the Super Bowls, I used the actual Vegas lines, since those are readily available. []
