I think it is possible the Pac-12 or 10 wasn't financially viable, especially when other conferences started shifting, but I think ideally back in 2012 or when it was the conference blends with the Big 12 and possibly let the Arizona schools go to a Big 12 division, leaving the 8 actual west coast schools to play each other and then 2-3 from the Big 12 each year and then have a championship game. That's still a bit shifty though and I wouldn't be surprised if Texas would have been drawn the SEC at some point anyway and blown everything up.
