pretend like they're above the rivalry and don't care about BYU anymore, which you seem to be suggesting we do ourselves. BYU-Utah is an awesome rivalry, and rivalries are one of the coolest things about college sports. I will continue to embrace the rivalry and will readily admit that I care about it, and part of that, for me, is cheering against Utah and wanting them to lose every single game.
I think the whole "let's try to be cool by pretending like we don't care" crap is pathetic, whichever side it's coming from.
