I think a lot has to happen to other teams now, since we have the one loss. We'd need to see many of those undefeateds ahead of us lose, and we must, MUST, win out. Seems pretty obvious, but look at the teams ahead and look at what they have left to do. I'm not sure anyone in the major conferences has as tough of a road schedule as we do. Essentially, outside of Duke, every road game we will have played will have been against top flite, top 10 schools. How often does that happen?
Boise isn't going to lose a game. TCU vs. Utah will leave the winner undefeated as well. Still, a one loss, SEC champ might get into the BCS title game before any of those. But what about Oregon, who doesn't play a conference championship game, has already beaten Stanford, and only has Arizona left to go. Perhaps Oregon State can get them. A one loss SEC champ like Alabama would likely get into the BCS championship before a one loss Pac 10 team.
So that leaves Ohio State (who is on it's way to Glendale), and guess who? Auburn. They are the only other one ranked ahead of us. And we play them head to head, at home. If this team has the strength to repeat, and I'm not sure it does, it goes through Auburn. We do play LSU before that, but they aren't ranked ahead of us. THAT game will likely be tougher than even Auburn, because of the road trip, and because they are defensively MUCH better than anyone else we have played. Better possibly than even South Carolina. Certainly better than Auburn.
It's a tough road to hold, but it can be done. Bama must win out, and some other things need to happen as well.
