One can argue about the point of models, but their general purpose is predictive. Again, are they more to approximate scores or identify which team will win? Many here likely feel that winning by 1, while less satisfying than by 21, is still winning. They likely take exception to the philosophy strongly implied by Herman's statement that "you only need to win by one," namely that shooting for marginal success is not an unnecessarily risky proposition. That said, the difference between winning by 1 and losing by 1 is much bigger than the difference between winning by 1 and winning by 11. People go crazy when a last-second FG lifts them from, say, down 24-25 to up 27-25. A lot of models don't much care. Going 6-6 with 6 comfortable wins and 6 razor-thin losses is not remotely as good an outcome as squeaking out an undefeated season. If those models seek to predict, e.g., whether Texas will play in (and perhaps win) important post-season games, then they were objectively failures in that regard last year. They appear on track to fail similarly this year.
I don't think anyone here is arguing that Texas was as good as Clemson or Alabama last year (or now for that matter). Nor are people arguing that the models bear no relation to the system they seek to model and predict. Rather, especially with respect to SP+, the case has been made that (1) sound empirical scientific and statistical technique has not been used to develop the models, (2) this (or something) has resulted in some peculiar failings of the model-- of interest here because Texas is one of the teams whose winning it seems to predict least accurately, and (3) the author and advocate of the model has behaved in a manner to suggest that he both senses to a degree the need to improve his creation as well as that he refuses to concede publicly any of its deficiencies. To the contrary, he makes statements to suggest that the reality he tried to model was somehow failing to conform to his model rather than the converse. I think virtually all here would agree that to look like a title contender, Texas needs to stop losing to the Marylands of the world and to stop letting the Tulsas get back in the game; to suggest otherwise is to miss the point of the criticism leveled at BC and his SP+. Nota bene, however: more important than looking like a title contender is becoming one-- if Texas wins every game one the schedule by 1 point, they will be one.
Who will bet me straight up on his predicted W/L total for Texas if I get the over? Any takers?
