@sack,
first of all, you are letting your personal feelings interfere with your judgment. if ut leaves the b12, our tv money is going to be hugely diminished. that's bad for CU. this is all about tv markets. this is a fact and no matter how many times you complain about ut the conference-killer (and i happen to agree with that, for the most part), the fact won't change.
second, you are presuming that ut in the p10 would be as powerful as it is in the b12 and was in the swc. there is no guarantee of that. for one thing, the way the voting is set up in the p10, ut would be less powerful. also, the center of gravity for the conference is the west coast, even with the weight that ut brings to the table. usc, ucla, stan, and cal, among others, can hold their own against ut, politically and economically (at least, relatively). it would not be my preference to have ut join the p10 for the same reasons you don't want them there, but i am worried that we could be the ones left without a chair when the music stops if the p10 decides to first expand with ut and atm.
if ut leaves, the b12 is not going to be the place you want to be if you want to try to remain competitive in big time football.
