If BYUTV is standing in the way of Big 12 membership, then throw it away. The replays are not worth very much and BYU would be just as likely to be on national TV in the Big 12 as they are Indy. The only BYUTV football games are against silly opponents like Idaho State.
BYUTV may have some value, but being left out of P5 in the current environment could kill the entire football program in a decade or two. Hawaii is talking about killing its program just a few years after being in a BCS bowl.
