And the better team, IMO. I also agree that USC should play the SEC Champ should Oklahoma fall to Mizzou. For that to happen, they'll have to jump them in the Harris and USA Today polls. Right now, Texas holds about a 6% lead in the Harris and Coaches' polls. They are up 21% in the computer average. It will be strange if two teams flip flop in the BCS while both are idle.
EDIT: Since they are idle, the computer averages won't change (not much at least). If you assume the percentages in the other two are fairly consistent for the slot, then you can approximate what the rankings would have to be (assuming equal amounts gained in each). To wipe out the 21%, they need a 22% gain in the other two, 11% each. Assuming USC gets ranked #2, about 91%, then Texas will have to fall to #6 (#5 is about 84%, #6 is about 75%). I don't see that happening. Can you put 5 teams ahead of Texas if Oklahoma loses?
