At 13-0, we'd be behind 1 loss teams with names like tOSU, USC, LSU - any school that started the season in the top 10. Probably would be behind a 1 loss hawaii too.
We'd get the guaranteed BCS bowl, but not the title game.
Like Kansas was last year?
All they had to do was win out, and they were playing in the BCS championship.
If we go 13-0, we would be a lock for the BCS championship PROVIDED there were not two other undefeated teams from BCS conferences. The Big 12 is a tough conference. The north may be tougher this year than the south. And we would have to beat every team in the north and the best team in the south to go undefeated.
