Until last night, only one team in the Big-12 had a quality win on the road: Ok State beat Missouri in Columbia. Oklahoma went on the road last night and beat #12 Ok State, in a game that was closer than the final score would indicate. OU showed heart in not crumbling under an offensive juggernaut on the road.
Don't let anyone kid you: playing Texas in Dallas is a road game for Oklahoma. Even so, if their defensive captain hadn't been knocked out for the season in the first half, the final score might have been much different. OU has been compensating for that with more offense ever since.
Oklahoma has a win against the Big East champion. Texas has a win against Arkansas.
The BCS will do whatever it does, and OU will either play in the Big-12 championship next week or they won't. But it's obvious to me that Oklahoma is playing the best football right now. Not Florida, not Texas, not Alabama, not USC.
