I am not saying you're wrong, I'm just not sure why you believe that.
And are you saying, that, since it'd be worse for Utah if BYU was in the Big12, then Utah should be proactive and get BYU in the Pac12?
I just think that if the roles were reversed and BYU was in the Pac12, most of us would say NO to having Utah in the Pac12. And in that scenario, I also think that I would rather have Utah join the Big12.
