The Oregon Ducks and Utah Utes are in a comfortable position with regards to Pac-12 tournament seeding. They have already clinched their first round byes as neither team can finish with no more than six losses, and all but four teams have six losses already. They'll avoid having to play an extra game.
So that leaves three teams vying for two spots: The California Golden Bears, Arizona Wildcats and the Colorado Buffaloes.
Colorado must beat Utah to have a chance. A loss, and Cal and Arizona immediately clinch first round byes regardless of how their weekends go.
