Indeed they would cream. But the only problem is Oklahoma has no chance in hell of making it there. OU will lose to Texas.
Baylor looks decent so far, I wouldn't consider them a walk for OU, and Tech looks no worse than Oklahoma does this year. And as you said Oregon, A&M, and Mizzou will be tough, I'm calling OU loses to at least two of those five teams, along with Texas.
Nebraska is in a similar situation,(USC, Texas, Mizzou, A&M) but the weak North is to their advantage.
