If BYU gets to the CC game undefeated and loses, the committee would have to choose between BYU or a 2-loss Miami or 2-loss SMU both of which BYU would have a leg up on.
I don't see a 3-loss SEC or BIG team taking a 4th spot over 1-loss BYU.
So, win the conf. Championship game or at worst get there undefeated and if we lose we should still get in.
