Oregon's precipitous slide and Washington's rise highlighted the opening half of the Pac-12 season. Colorado and Utah could shape the finish.

The Ducks and the No. 5 Huskies had last week off but the last time they played it was against each other, and undefeated Washington romped 70-21 at Autzen Stadium. The victory ended Washington's 12-game losing streak to rival Oregon.

The game illustrated the rise of the Huskies, off to their best start (6-0, 3-0 Pac-12) since 1992, and the quick fall of the Ducks, who played for the national championship two seasons ago but have dropped four straight to sit at the bottom of the Pac-12 North (2-4, 0-3.).

With a nine-game winning streak dating back to last season, the Huskies host Oregon State on Saturday. The Ducks will visit Cal on Friday night.
