No, seriously. Would any BYU fan, anywhere on the planet, turn down an offer to play in the Big12 just because financially, it was a lateral move? They could pay half what our current deal pays and it would still make sense to go. People talk about TV money as though they personally get a cut and can't afford to make their house payments unless BYU signs a bigger TV deal.
BYU athletics aren't hurting for cash and if they are it's because they haven't been fun to watch for so long that donor money is drying up, not because of a TV deal. Sacrificing a couple million bucks a year to get into the Big12 would be a major coup.
