You remember when the AAC almost added SDSU and Boise and became a truly Nation-wide, Best of the Rest conference?
That is now the Big-12. The blue bloods of the Big-12 have to be looking towards the PAC-12 as their savior. I think the PAC will eventually take most, if not all of the original public Big-12 schools. No way they take any Christian schools.
And, the Big-12 will continue to be the Best of the Rest Conference.
