I actually think GK gets too much heat. No one watches Pac12 sports, what kind of deal was he supposed to get? GK lying to everyone and being overly optimistic about how much money he though they could get was a terrible approach, but I don't think another commissioner would have magically saved the conference. Once it was clear they were only going to get like 60-70% of the Big 12, the Pac12 was doomed.
As for the Pac12 ADs. It seemed they've just been sitting on their hand for 1-2 decades doing nothing to drum up fan support. Pollard spent 20 years promoting football, touring the state, etc.. to get the Iowa State fanbase to where it is now, mostly on the backs of losing seasons too.
