As a guy that loves baseball sabermetrics, I think football sabermetrics are foolish, if honest mistake, and aren't really the best way to look at football teams. I remember the Bears were still a negative DVOA team overall well into like week 14. Its a dumb stat. It's a great way to look at football teams. It's a sketchy way to look at individual performance, because so much of football performance is team-dependent. I'm not sure if you realize how awful the Bears were from weeks 4-7. And on week 14, for that matter. However, they've been so good since week 9, especially defensively (they've been second overall since then, 3rd against both the run and pass), and even slightly above average offensively. Thinking a stat is foolish because it doesn't reflect well on your favorite team is a foolish reason. No its stupid because each play is not equal, and there is so much context in each throw, every running play, every down that its impossible to take those things into account. I understand that there are contingencies and they try to see what plays are succesful based on what down it is, and all that, but its still impossible. Its a nice try, but its dumb. Its nothing at all like baseball where every at bat is basically the same for the batter no matter what. And I should simplify this even more: Baseball statisticians still aren't close on getting a consensus on baseball defense, and thats is one million times more simple and cut and dry than what goes on a football field.
