Florida will win.
You drastically overestimate Sam Bradford and the rest of the OU offense, especially because they (and their hurry-up) have not scored 60 on an SEC defense. Especially because they are without their leading rusher.
I wrote a much more comprehensive piece, but somehow, I managed to navigate elsewhere over it. (And, thus, I lost it.)
I expect your prediction that Oklahoma will win " big" to turn out much the same as your "lock" that Tebow would win the Heisman.
One other thing -- the reason the Big XII-hurryup worked so well (and by "so well", I mean Texas barely won) in the Fiesta Bowl is because the competitor was OSU. The SEC is not quite on par with the Big Ten. Sorry, Doyel. I think Florida will be ready.
A reiteration: 49-35 Florida.
