From Pullman — Washington State was out of action of Thursday, so we took another look at the overtime loss to No. 15 Colorado. I also put out my power rankings, which were quickly and thoroughly made worthless by a slate of Pac-12 games. No. 17 Oregon continued to slide, falling to Cal, which is looking like one of the conference's best teams despite having a few key players out with injuries … Oregon State picked up a conference win against Stanford, which is surprisingly struggling so far in Pac-12 play … Arizona edged UCLA in the night's marquee matchup … And USC proved to be an easy outing for the Sun Devils.
