I'm afraid AZ is marginal but your point stands. Killing the Pac doesn't matter if we take the worst. Hell, it could help! Lose OSU and Wazzu and pick up the SD rockstar!The goal of adding Pac12 teams is to keep payouts per school equal to better than projected based on the new Big12 (w Cincy, UCF, Hou & BYU).
Adding CU, UA, WSU & OSU would not accomplish that. WSU & OSU are probably the 2 least valuable properties in the Pac12. CU & UA might be around the Big12 breakeven payout per school. Adding Pac12 schools only makes sense if 2 of 4 teams added by the Big12 are among: ASU, UU, OR, UW.
Destabilizing the Pac12 doesn't do any good if it destabilizes the Big12!
