Some Pac-12 numbers for your review.

Number to the left is national rank.

Scoring offense

2. Oregon, 55.6 points per game

6. Arizona State, 46.6

25. UCLA, 37.3

Total offense

2. Oregon, 632.1 yards per game

10. Arizona State, 515.1

15. Washington, 501.9

26. Oregon State, 474.2

8. California, 351.1

17. Arizona State, 324.7

20. Oregon, 300.6

23. Washington, 283.8

Note: It's becoming clear that Oregon and Arizona State have the two best offenses in the Pac-12. It's also clear that Pac-12 offenses, on the whole, aren't terribly efficient. Oregon ranks second in the nation in yards per play at 8.09. The next conference team is Arizona State, way down at No. 27 (6.28 yards per play).

Scoring defense

7. Oregon, 16.9 points per game

T19. USC, 4.92

26. Washington, 5.0

Pass-efficiency defense

6. Oregon

14. Washington

15. Arizona

20. USC

26. Arizona State

Note: Arizona's improvement on defense has been remarkable, but that improvement will be strenuously tested by the upcoming schedule, starting with a visit from UCLA on Saturday. Also ahead: Washington State, Oregon and Arizona State. If the Wildcats maintain a top-25 defensive ranking by season's end, coordinator Jeff Casteel should be Assistant Coach of the Year.

Rushing

1. Ka'Deem Carey, Arizona, 153.1 yards per game

3. Bishop Sankey, Washington, 145.3

17. Tyler Gaffney, Stanford, 110.8

18. Byron Marshall, Oregon, 109.9

Note: Stanford will need Gaffney to hit this number if it hopes to beat Oregon on Thursday. And it needs to keep Marshall off his average, too. Carey will be challenged by a UCLA run defense that yields only 3.9 yards per carry.

Pass efficiency

5. Marcus Mariota, Oregon

16. Sean Mannion, Oregon State

21. Brett Hundley, UCLA

25. Keith Price, Washington

27. Kevin Hogan, Stanford

28. Taylor Kelly, Arizona State

Note: Mariota fell to No. 2 in the nation in ESPN.com's Total QBR behind Baylor's Bryce Petty. Arizona State's Taylor Kelly has surged to eighth in the nation in QBR. Eight Pac-12 QBs rank among the top 43 in the nation in QBR.

Receiving yards per game

1. Brandin Cooks, Oregon State, 149.3

5. Paul Richardson, Colorado, 123.0

30. Chris Harper, California, 91.2

31. Jaelen Strong, Arizona State, 90.0

Sacks

2. Trent Murphy, Stanford, 1.2 sacks per game

T10. Tony Washington, Oregon, 0.9

T21. Devon Kennard, 0.8 (in 9 games)

T27. Anthony Barr, UCLA, 0.9

T27. Hau'oli Kikaha, Washington, 0.9

Note: Murphy has labored in Barr's shadow, but he can make a name for himself on Thursday if he can take down Marcus Mariota. Barr will be chasing Ka'Deem Carey and B.J. Denker on Saturday. Murphy is fifth and Barr tied for seventh in the nation in tackles for a loss (1.7 and 1.6 per game, respectively).
