You don't blame Utah fans (or other PAC team fans) for being condescending? It's just human nature to be condescending when threatened? Sorry, but I disagree.
The Big 12 survivors all have one thing in common. We're all pretty humble because, unlike any other power conference, we've been poached 3 times over the last few decades. We're finally at a point where all the prima-donnas in our conference have exited.
I realize the wisdom of adding PAC teams to our conference, and I definitely think we should move in that direction, but I'd suggest adding only 2 (probably AU and ASU) to begin with. That will be enough to eliminate the PAC as a competitor. Then we offer UO and UW, but with no special privileges. Then only as a last step do we offer UU and UC.
Letting Utah and Colorado twist in the wind and experience some humility would do them good. The last thing we need is to beg other prima-donnas to join our league.
