You also realize that they are getting more and more pressure to only schedule P5 teams in the future right?
So yeah, BYU could probably schedule 2-3 P5 teams as a member of the MWC over the next 4-5 years, but that will eventually go away and it will become more and more difficult to do so and eventually they won't be able to do it at all.
But that shouldn't matter to you MWC guys though. As long as we're beating up on the little sisters of the poor, all is well right?
