I wouldn't mind seeing a re-shuffle akin to how the MWC was formed out of the dysfunctional WAC in 1999.
Even with the long history of the PAC, if some of those programs put that aside and decided to scrap it to discard some weaklings (Wazzu, Ore State, Cal) while some of the Big 12 did the same and melded a league of TCU, OSU, WVU, Baylor, Tech, KSU USC, UCLA, Stanford, Washington, Oregon, Utah and Cal with possibly holding their nose and taking BYU, this could be a very stable and competitive league.
