PULLMAN – After this week, we may have a new No. 1 atop these power rankings. If not, who knows when the Ducks will finally vacate their perch? The Cougars have this weekend off, but their next opponent, Arizona, will host UCLA in a surprisingly big game for both teams. The Bruins have looked great this season but have two Pac-12 losses, albeit to the conference’s two best teams. Arizona, on the other hand, is riding a three-game winning streak. Both teams will be looking for a win to show that their success wasn’t merely a facade.
