(I originally posted this at the S-R Blog, but I thought it would be very appropriate here as well.)

Here is a google doc containing every team-season in our database since 1957, including the Head Coach and offensive & defensive coordinators. It also specifies those coaches’ preferred offensive or defensive schemes (depending on which side of the ball they specialize in), and attempts to figure out the general offensive family (i.e. Air Coryell, Erhardt-Perkins, etc) each team-season fell into.

THIS IS BY NO MEANS COMPLETE. In fact, it’s very much incomplete at this stage — and that’s where you come in. In the comments of this post, or in an email, we’d love to hear corrections and/or additions to the data, if you see an entry about which you know more than we do (and it’s a good bet you do). Thanks in advance for your help, and hopefully we can assemble a more complete listing of teams’ systems/schemes, which will let us do things like compute splits vs. a certain type of offense or defense, analyze whether 4-3 or 3-4 defenses were better in a given season, etc.

So let those corrections/additions pour in!
