I could see a scenario where the two Arizona schools + Utah look into playing their OOC games outside of PAC 12 control. I would've put USC into this as well but it looks like they're already backing out of the Alabama game. It might not be a battle worth fighting, though, since obviously PAC 12 authorities dictate conference play.
Both Arizona schools are more business-savvy (in a practical sense) than the rest of the conference. Both have announced hybrid classes (mix of online, on-campus) for the Fall semester, with the decision upgrading back to fulltime classes expected sometime later this summer.
Like Florida, I can definitely see the state of Arizona looking to profit on the hesitation and caution of California. LA County's decision to remain closed for opener three months (!) was a big eye-opener earlier this week. As someone who lives in Southern California, I can tell you that a lot of us, looking down the barrel of a shut-down summer, are already talking about going where the pools, spas, sports bars, and golf courses dare open.
