With the news of USC and UCLA joining the Big 10 it raises a lot of questions regarding the future of the PAC 12 and the remaining schools. But what about all the schools who are scheduled to change conferences next year? The Big 12, the American, the MAC, the Sun Belt, and C-USA are all expecting new members. But is all that locked in at this point since no one has actually joined yet? I could see the Big 12 wishing they could go after some PAC 12 schools rather than some of the American conference schools they are scheduled to get. Or maybe a school sees an opportunity to join a better conference. So, is there a possibility that someone will back out of one of these agreements or is it set in stone at this point?
