Here's how the five Pac-12 teams in the top 25 fared in this week's blogpoll.
The Oregon Ducks stayed in second place after routing Washington State. Their position is likely secure as long as they win.
The Oregon St. Beavers moved up from 19th to 13th after a convincing road win over Arizona. It remains to be seen how strong Arizona actually is, but the resume for the Beavers has never looked stronger.
The USC Trojans couldn't handle bye week well enough. They dropped a spot.
The Stanford Cardinal plummeted ten spots from 8th to 18th after their tough loss to the Washington Huskies.
The UCLA Bruins rose all the way from 28th to 24th after taking care of business against the Colorado Buffaloes.
The Washington Huskies are hanging around the top 25 at 28th, and would probably leap up with an improbable upset of Oregon this week. Arizona State is also close by at 34th after an impressive road win against Cal, and Washington State inexplicably has a vote.
