Interesting comment on the refs. The Pac 12 refs enter any game with a committment to facilitating an event in which things spiral out of control until there is a culminating assault and major injury (and then usually call a foul against the player who's most unconscious). At that point they retreat to ticky-tack calls--until the final minute, where it again becomes a free-for-all.
We're anxious to escape Pac 12 officiating as well.
It's a little bit that we're the new guys. Pac-12 refs are the western guys who do P12, WCC, WAC & MWC so they're not as familiar with us as the Big 12 refs were. That can influence things like getting the 50/50 calls on the home court.
But this year I think the big deal is that P12 refs got embarrassed nationally by the shot clock call at the end of our game at Arizona. Tad piled on with his post-game comments. Since then, I don't think they've been in the mood to do us any favors.
