The PAC 12 has backed itself into a corner when it comes to bringing in new schools. The conference requires all members to be Tier 1 research universities, and schools like Boise and San Diego St don't qualify. There are Tier 1 schools in the MWC (Colo St, New Mexico, UNLV, Utah St), but they don't offer much sports wise. There are also some Big 12 schools who are Tier 1 (Baylor, K-St. Texas Tech), but I can't see them leaving the B12 for an unstable league like the P12.
I bet the B12 is spanking themselves for admitting the four mids (UCF, Cincinnati, Houston. BYU) they accepted last year. Had they known the PAC 12 was going to be in trouble after losing USC and UCLA, they could have grabbed established Power 5 programs like Utah, Arizona St, Washington, Oregon etc. BYU is a solid get, but even schools like Wash St, Cal, or Ore St would have been better than UCF, Houston, and Cincinnati.
I still don't believe both the Pac 12 and Big 12 can survive as P5 conferences. I think there will be some type of merger, or even schools from both leagues joining together to start a new conference. The left overs could either join the MWC, join the WAC and revitalize it as a football conference, or start a new mid major league.
I will say going to see a game at San Jose St is a lot more fun than going to see Cal or Stanford.
I like the college atmosphere much more than the pros, and for me SJS is just a lot more fun. Cal and Stanford: too serious.
Come to think of it, those are the only college FB stadiums I've been to, and none of them have much of a parking lot so no real pre-game atmosphere either. At Stanford I've always parked on campus on grass between trees and bushes, sort of a free for all and a zoo trying to find your car and get out. In Berkeley it's free street parking but you have to walk a ways, at SJS its nearby side streets with mostly warehouses and ancient business parks, all closed on Sat.
