I don't think there is anyway that Oklahoma can go undefeated. They play down in too many games, and they play lots of teams who can beat a "down" OU team. The biggest chances at losses being,
KU right after Texas, TT usually does good against OU, and at Washington. That's right I am calling it now, OU will lose to Washington.
I would be happy though if the records would turn out like that though.
