I'm in the process of constructing a database of every NFL game played between 1997-2007, including preseason and postseason (separated, of course). The information I'll be including is:
Teams (obviously)
Score
Spread
Total Points
O/U
Game in relation to bye week
Whether in division, and whether 1st or 2nd game
Consecutive home and away games
Starting QB (difficult, I may drop this one, unless I hit the microfiche)
Head coach
Building
I'm also considering doing weather as well, but I'm not sure about whether I want the undertaking. My question is whether there's anything I'm forgetting that would be potentially helpful information. I may extend the database to before 1997 as well once I'm done with what I've set out to do. I've got 20 teams so far, and I hope to be done by around February.
