The Pacific-10 Conference season starts this weekend for the Oregon State football team with a home game against Arizona.

Some conference games have already been played by other teams, but now it really gets hot and heavy. Here’s the beginning of my weekly power poll, which is a look at how the rest conference is doing.

1. Cal: Bears keep rolling along. Beating Minnesota on the road was big last weekend. Could this be their year? Only as long as Jahvid Best stays healthy.

2. USC: Mighty Trojans had their once-a-year slip-up, this time against the Huskies. The Cougars are going to get hammered this week.

3. UCLA: Being 3-0 is impressive no matter the schedule, but the win at Tennessee was impressive. And there’s a good home win over Kansas State.

4. Washington: From low-level team to mid-pack with a win over USC. The Huskies have to do something at Stanford this week to not be a flash in the pan.

5. Arizona State: Two easy wins against lesser opponents is one thing, but the trip to Georgia this week will tell more about this team. Expect the Devils to drop next week.

6. Oregon:  Wins over Purdue and Utah were nice recoveries from the Boise State incident. This week’s Cal game should be interesting.

7. Oregon State: Game with Arizona this week is crucial to win and stay on track. Beavers need to take the next step or will be left behind.

8. Stanford: Co-leader of the conference with Washington after season opening victory over WSU, but hasn’t played anyone tough. The loss to Wake Forest was to a solid team but not an ACC power.

9. Arizona: The Wildcats beat low-level teams and couldn’t be a mid-level Big Ten team. They are solid but a win this week makes them a team to beat.

10. Washington State: That was good for the Cougars to take SMU. It’s not looking good this weekend and beyond.
