In some ways I'm more worried BYU would lose to a 2-9 Utah team than an undefeated one. Too easy to take a 2-9 opponent lightly, even though it's a huge rivalry game. It also might be easier for a 2-9 Utah team to get up for their "bowl" game.
That being said, regardless of their respective records at the end of the regular season, I hope the Cougars rename Rice-Eccles. Let's call it LES North.
