Whoa, Nellie! Empirical Tests of College Football's Conventional Wisdom

I'm not enough of a sports fan to want to spend the $5 it costs to read it, but this academic paper sounds intriguing and the kind of thing -- in theory -- statistics-oriented newspaper reporters could do, if so inclined. It's by an economist at Ohio State who specializes in economic history, economic demography, and biodemography:

College football fans, coaches, and observers have adopted a set of beliefs about how college football poll voters behave. I document three pieces of conventional wisdom in college football regarding the timing of wins and losses, the value of playing strong opponents, and the value of winning by wide margins. Using a unique data set with 25 years of AP poll results, I test college football's conventional wisdom. In particular, I test (1) whether it is better to lose early or late in the season, (2) whether teams benefit from playing stronger opponents, and (3) whether teams are rewarded for winning by large margins. Contrary to conventional wisdom, I find that (1) it is better to lose later in the season than earlier, (2) AP voters do not pay attention to the strength of a defeated opponent, and (3) the benefit of winning by a large margin is negligible. I conclude by noting how these results inform debates about a potential playoff in college football.

I just have a hard time believing that, universally, it is better to lost late in the season than earlier. That might be true for Kansas this season, but it wasn't the case for Ohio State. If the Buckeyes had lost to Illinois in week 4, they be bucking for a #1 right now. But I'm sure the guy is still pretty smart
