Pac-12 quarterbacks in the middle of the board made moves in Week 6. Now, a top-10 showdown in Seattle this weekend (plus a top-25 battle in South Bend) creates a massive opportunity for the top of the board to completely change.

Here’s Saturday Out West’s Pac-12 quarterback power rankings entering Week 7. These will be updated weekly throughout the season.

12. Ashton Daniels/Justin Lamson, Stanford

Last week: 12

The Stanford duo was off last week, so this section is taking a week off as well.

11. Jaden Rashada/Trenton Bourguet/Drew Pyne, Arizona State

Last week: 10

Bourguet moved the ball throughout, but there was just too much inconsistency. ASU scored on its opening drive, then went three-and-out on the next three possessions. Then it scored another touchdown. Then it went three-and-out again. Bourguet threw for 335 yards and a touchdown. He was under duress. It was a meh performance for me.

10. Sam Jackson V/Ben Finley/Fernando Mendoza, Cal

Last week: 11

Utah’s Kyle Whittingham said he wasn’t expecting to see Mendoza when he turned on the Oregon State tape. That move happened on the fly, but not without merit. Jackson has struggled and Finley hasn’t been able to find wins. Mendoza emerged as the third quarterback to play this year and put 40 points on Oregon State. After a scoreless first quarter, Cal scored 32 in the second and third to head into the fourth trailing by just three. The defense let Cal down, but the pass game showed some signs of life.

9. Bryson Barnes/Nate Johnson, Utah

Last week: 9

Utah was off last week, so this section is taking a week off as well.

8. Dante Moore, UCLA

Last week: 7

In a 25-17 win over the No. 13 team in the country, Moore cost UCLA points. He had two more interceptions, one of them returned for a pick-six. That’s back-to-back outings with an interception taken back on him. I trust Chip Kelly here when he says this is simply a case of a young quarterback going through growing pains. Moore shouldn’t have a quick hook; the ceiling on this team is far higher with Moore than Garbers or Schlee, and if you can ride out some of this now, you’re much better positioned to face USC in November. Moore faces a huge moment in Corvallis. A win could set the table for a special UCLA season. UCLA needs him to be cleaner.

7. Jayden de Laura/Noah Fifita, Arizona

Last week: 8

I agree with Jake Dickert. I don’t know how you don’t roll with the young guy. Fifita went up against another top-10 team in his second career start and threw for 302 yards and five touchdowns while completing 71% of his passes. I kind of think Jedd Fisch’s messaging this week — that de Laura will back up Fifita if he’s anything less than 100% — is more about wanting to continue riding with the hot hand without losing his options.

6. Cameron Ward, Washington State

Last week: T-3

You are just going to be in for a horrible day when you face the UCLA defense. Ward entered the game as one of the nation’s top passers, piloting one of the nation’s most prolific offenses. That all came to a screeching halt in Pasadena. Ward was picked off twice, held to a 49% completion rate, and managed just 197 yards through the air.

5. Shedeur Sanders, Colorado

Last week: 5

Arizona State has a top-30 pass defense by efficiency. They haven’t been able to take the football away, but they’re making life tougher on opposing quarterbacks. Sanders had just 239 yards on 26-for-42 passing. He threw only one touchdown pass — in the fourth quarter as CU began its comeback. I love the watch flex. Keep doing it. I also think it was hilarious to see it after winning that game the way Colorado did. Sanders had an OK game by his standards; he made plays late, but it took him a bit to unlock things.

4. DJ Uiagalelei, Oregon State

Last week: 6

Uiagalelei showed again in Week 6 why he’s the guy Jonathan Smith needed to complete this puzzle. DJ U threw for 275 yards and five touchdowns. He completed 76% of his passes and didn’t turn the ball over. Oregon State scored 52 points and won a shootout. Now can he do it again against a much better defense?

3. Bo Nix, Oregon

Last week: T-3

2. Michael Penix Jr., Washington

Last week: 2

Nothing changed here with Nix or Penix as both Oregon and Washington were on a bye week. But the stage is all theirs in Week 7 to make a move in the Heisman race and, more importantly, take Caleb Williams’ spot atop these rankings.

Penix currently leads the Pac-12 in Total QBR. Nix is 13th nationally. When folks look at these teams, Penix jumps out as the guy leading UW while Nix fits into a more complete team. At least, that’s the national perspective. Nix will have a chance against a gettable UW defense to prove his Heisman campaign is one to take seriously. Penix will have a chance to create some distance between himself and the field.

We don’t usually get Heisman moments in October, but a big game here for one of these quarterbacks will lead the résumé later in the year.

1. Caleb Williams, USC

Last week: 1

What would happen if Williams had a top-25 defense? Or even a top-50 defense? They might be the No. 1 team in college football right now. But USC ranks 80th in scoring defense and 83rd in defensive efficiency. I get the sense Williams is starting to feel some of that pressure. The 43-41 win over Arizona saw USC open the game with some sloppy play on offense as early third-downs felt way more “all or nothing” than they should have. Williams finished with just 14 completions. Yet he scored four total touchdowns and converted the game-winning two-pointer in triple-OT to drag USC across the finish. Williams is third nationally in EPA. He’s the most valuable man in college football. Imagine where USC would be if it didn’t have him.
