Tiebreaker Procedures - Big 12 Conference - Official Athletic Site Assuming Oklahoma, Texas, and Texas Tech all win next week (Oklahoma is the only one with a real challenge), they will be in a 3 way tie for the Big 12 South. So, it looks like it will come down to the BCS ranking, which gives the edge to Texas. Unless the thumping Oklahoma's giving Tech boosts them over Texas, which isn't all that unlikely. If Oklahoma loses to Oklahoma St next week, Tech goes to the Big 12 Championship. And, of course, if one of those three teams wins the Big 12 Championship, they'll be in the national championship against the winner of Alabama/Florida (my guess is Florida). If, somehow, Missouri pulls out an upset win in the Big 12 Championship, USC sneaks into the BCS championship (assuming they win their last two games...which isn't a given). Let's say Missouri DOES win the Big 12 and USC loses another game, who goes to the BCS championship? Utah? Or would they put the highest ranked Big 12 team left, who didn't even win their own conference, in the championship? It's gonna get interesting.
