I’m guessing USC/UCLA would be a package deal, neither of them would come unless they both do. I also like the idea of adding Cal/Stanford - both having good/great athletics (at least outside the revenue sports) and high-level academics. I’d add Washington if they wanted in, same with Colorado. That’s a 20-team league if they all want in. I’m indifferent about the Oregon and Arizona schools and probably just don’t know enough about them to form an opinion one way or another (outside the OU/Nike relationship).
But add the LA, Bay Area, Seattle, and Denver markets, plus the high-level academics they add, that’s a juggernaut of a conference that I’m not sure even the SEC can match from a revenue perspective.
