There's absolutely no upside to playing BYU anymore.
In light of everything Max Hall said, the rivalry probably needs to take a break anyway.
Just look at it from Utah's point of view. If Utah wins, it's no big deal. Just a BCS team beating a Non BCS team.
However, if BYU wins, Utah looks like garbage and the fans all freak out because Utah should never lose to BYU.
It's a no-win situation for Utah.
