the CFP committee will already be working against non-P2 teams. An Iowa state loss also increases our chances at making the CCG.
The higher we're ranked, the more we can potentially absorb a loss and get into the CFP as a non-conference winner.
Sure, an undefeated Iowa State CCG matchup could help us, but better to climb the rankings now. For a subjective playoff, the more our BYU logo is showing up on projection graphics the better.
