Bama's best wins are at Penn State, Arkansas, and at Florida. PSU has no offense whatsoever and UF turned out to be way down this year. Arky is a nice win. On the other hand, the Tide managed to avoid USCe and UGA, the east's two best teams. Their non-conference schedule consisted of Kent State, North Texas, and an FCS school. Bama has played 4 teams with a winning record if you include Georgia Southern, and lost one (to LSU at home).
While U-LaLa and Tulsa might not be worldbeaters, they've proven to be quality teams in their conferences. KSU is having a nice year, and we went on the road and beat Aggy, UT, and Mizzou. We curbstomped both Baylor and Tech, two teams that our defense was supposed to struggle defending. Even if you think the Big 12 is overrated (and I agree that they are in the computer rankings), you can't seriously argue that top-to-bottom our schedule wasn't way tougher than Bama's.
Bama's schedule is quite shockingly weak. It's not necessarily their fault, but when you combine our resume (assuming we get a win over OU) and the fact that LSU already beat Bama at home, I think a lot of pollsters will be sympathetic to our cause.
