Man this thing was close. Very close. And it came down to the human vote. OSU had the edge in SOS (#9 versus #42 for Bama). So the BCS computers liked OSU more than Alabama: The computer rankings for OSU: Anderson/Hester #2, Jeff Sagarin #3, Richard Billingsley #2, Colley Matrix #2, Kenneth Massey#2, and Dr. Peter Wolfe #3.

But Alabama beat OSU in both human polls. The Coaches Poll was very tight: Alabama = 1399, OSU = 1367. The Harris Poll was also close: Alabama = 2723. OSU = 2654. LINK (AP Poll is no longer used.)
In the end, it would have taken a very small number of people—I'm guessing 50 or so—to sway the outcome. Frankly, I would have rather seen OSU in the game than give Bama a second crack at it.
