The Colorado Buffaloes dropped to 1-1 in Pac-12 play following Saturday's 42-14 blowout loss to UCLA. The loss drops Colorado to fourth in the Pac-12 South division.

Colorado will have Week 6 off, before playing host to Arizona St. on Thursday, Oct. 11.

The Pac-12 standings received another shakeup in Week 5, as the Stanford Cardinal were upset by the Washington Huskies, dropping Stanford to fourth place in the Pac-12 North division.

Stanford had two weeks to prepare for last Thursday night's contest against Washington, but still lost to the Huskies, 17-13. The loss dropped Stanford behind Oregon, Oregon St. and Washington in the Pac-12 North.

As expected, the Oregon Ducks sit atop the Pac-12 North standings, tied with the Oregon St. Beavers at 2-0. Both the Ducks and Beavers are ranked in the top 15 of the latest AP Poll, and both teams clearly look like the class of the Pac-12 North to this point.

The Pac-12 South, however, is a bit messy. The Arizona St. Sun Devils are the only undefeated team within the Pac-12 South, but that is likely to change with games against Colorado, UCLA, Oregon St. and USC on the horizon.

With so many Pac-12 games left, a lot can, and will, change before we know who will be playing in the Pac-12 title game for the right to play in the Rose Bowl.
