Even if they win they are not likely going to the BCS games. They need UCLA to beat Stanford, Florida St to beat Georgia Tech and Nebraska to win the B1G.
It would be cleaner if TCU just beats them though.
If they (OU) win and somehow Texas beats KSU they win the conference and go to Fiesta Bowl.
FSU is going to kill GT (who is 6-6) so I wouldn't worry about that but if FSU did lose, thats 3 losses and they are out.
Doesn't matter who wins between UCLA and Stanford--the winner goes to the Rose and Oregon goes to Fiesta probably.
Doesn't matter with NE and WS either. The winner goes to the Rose and the other is out. NE would have 3 losses.
OU is solidly ahead of Clemson (who doesn't play) now. If OU beats TCU they probably end up vs Florida in Sugar. Did you forget that a conference gets no more than two BCS slots.
The one wrench in the equation (other than losing to TCU) that could screw over OU is Kent State. They are sitting at #17. A few weird bounces of the ball and they could find themselves in an AQ position.
