Pac-12 power rankings, Week 2

With one week’s worth of games behind us, here’s the debut of our weekly Pac-12 power rankings.

Ranking/Team (overall record, Pac-12 record, streak)

1. Southern California (1-0, 0-0, W1)

Last week: W, 55-6, vs. Arkansas State

This week: vs. Idaho, 5 p.m. Saturday (Pac-12 Networks)

Comment: Trojans picked up a lopsided win in Week 1, but gave up a bunch of yards (and sacks) in the process.

2. Oregon (1-0, 0-0, W1)

Last week: W, 61-42, vs. Eastern Washington

This week: at Michigan State, 5 p.m. Saturday (ABC)

Comment: EWU is a solid outfit, no doubt. But allowing 42 points to anybody the week before traveling to East Lansing has to be considered alarming. Ducks have much to prove.

3. UCLA (1-0, 0-0, W1)

Last week: W, 34-16, vs. Virginia

This week: at UNLV, 7:30 p.m. Saturday (CBS Sports Network)

Comment: Josh Rosen couldn’t have looked better in his collegiate debut. Bruins are in business.

4. Utah (1-0, 0-0, W1)

Last week: W, 24-17, vs. Michigan

This week: vs. Utah State, 6 p.m. Friday (ESPN2)

Comment: It remains to be seen how good Michigan will be under first-year coach Jim Harbaugh. Regardless, that was a big win for the Utes.

5. Arizona (1-0, 0-0, W1)

Last week: W, 42-32, vs. Texas-San Antonio

This week: at Nevada, 4 p.m. Saturday (CBS Sports Network)

Comment: Wildcats defense could be in serious trouble for as long as it takes LB Scooby Wright to get healthy.

6. California (1-0, 0-0, W1)

Last week: W, 73-14, vs. Grambling State

This week: vs. San Diego State, 2 p.m. Saturday (Pac-12 Networks)

Comment: After thrashing an overmatched opponent in Week 1, Bears still have something to prove this week against Aztecs.

7. Arizona State (0-1, 0-0, L1)

Last week: L, 38-17, vs. Texas A&M

This week: vs. Cal Poly, 8 p.m. Saturday (Pac-12 Networks)

Comment: Lots of talk from ASU at Pac-12 media day about a national championship. Well …

8. Stanford (0-1, 0-0, L1)

Last week: L, 16-6, at Northwestern

This week: vs. UCF, 7:30 p.m. Saturday (FOX Sports 1)

Comment: There was reason to think the Cardinal’s offense might take a step forward this year. Fifth-year senior quarterback. A few solid receiving options. Talented tailbacks. But none of that showed up at Northwestern.

9. Washington (0-1, 0-0, L1)

Last week: L, 16-13, at Boise State

This week: vs. Sacramento State, 11 a.m. Saturday (Pac-12 Networks)

Comment: Huskies need at least a solid offensive performance this week to cleanse themselves of ugly outing at Boise State.

10. Oregon State (1-0, 0-0, W1)

Last week: W, 26-7, vs. Weber State

This week: at Michigan, 9 a.m. Saturday (ABC)

Comment: Underwhelming debut for Gary Andersen and crew, though the Beavers might be on to something with freshman quarterback Seth Collins.

11. Colorado (0-1, 0-0, L1)

Last week: L, 28-20, at Hawaii

This week: vs. Massachusetts, 11 a.m. Saturday (Pac-12 Networks)

Comment: Seemed plausible that the Buffaloes could go 4-0 to start the season. 3-1 still isn’t bad, right?

12. Washington State (0-1, 0-0, L1)

Last week: L, 24-17, vs. Portland State

This week: at Rutgers, 12:30 p.m. Saturday (ESPNU)

Comment: Worst loss in school history = last place in the power rankings.
