I don't think beating us 60-0 would impress any voters. They would be thinking "Who hasn't". It doesn't matter who is ahead in the polls when they meet, undefeated or not, it will matter who wins their game.
If Wyo luck were to infect the MWC; Utah beats BYU, BYU beats TCU, TCU beats Utah, noone from MWC goes to BCS game, but Boise freaking St beats some pathetic Big East or ACC team, ugh.
