The good news for the Utes is that ASU and UW lost yesterday. I believe they are now both out. That leaves 5 teams for 3 slots. UA and USC will make it IMO. That leaves UCLA, Standord and the Utes. I think the team which performs best in the PAC12 tourney will be that third team. If two of those three play for the PAC12 championship, they both might make it in.
Of course Colorado, Oregon and OSU could make it in, but they would need to win the PAC12 tourney to do so.
