Here is a quick look at some Pac-12 numbers and how they stack up nationally.

You can see Week 4 numbers here.

Number to the left is national rank.

Rushing offense

7. Oregon, 303.75

14. UCLA, 251.5

Note: UCLA and Arizona State's numbers took a big hit over the weekend, though the Sun Devils probably aren't fretting things after a blowout win.

Total offense

3. UCLA, 577.5

5. Oregon, 571.0

12. Arizona, 536.5

Note: None of these three is likely thrilled with its offensive performance from over the weekend.

Total defense

10. Arizona State, 274 yards per game

24. Stanford, 317.67 ypg

Note: ASU's number improved after holding Utah to just 209 total yards, the fewest the Sun Devils have allowed in a conference game since giving up 181 at Washington State on Oct. 10, 2009, according to the Arizona Republic.

Scoring defense

14. Arizona State, 12.75 points per game

18. Oregon State, 13 ppg

21. Stanord, 14.67 ppg

Note: Toss in USC and Oregon, and five Pac-12 teams are giving up fewer than 20 ppg.

Rushing defense

1. Stanford, 41.33 yards per game

2. Oregon State, 53.5 ypg

Note: Yep, the Cardinal and Beavers are the top two teams in the nation against the run. And neither can be accused of stacking an easy early schedule.

Penalty yards

30. Arizona State, 35.0 yards per game

32. Arizona, 42. ypg

Note: Arizona State ranked last -- 120th -- in the nation in penalty yards in 2011 with 79.77.

Sacks

7. USC, 3.75 sacks per game

10. Washington State, 3.5

10. Arizona State, 3.5

15. UCLA, 3.25

23. Utah, 2.75

Note: USC's big question mark was supposed to be its defensive line. It's exceeded expectations thus far.

Tackles for a loss

1. Arizona State, 9.75 per game

3. Stanford, 9.67

13. USC, 8.25

16. Washington State, 8.0

Note: Obviously, the Sun Devils, Cardinal and Trojans are getting better results from attacking than the Cougars.

Pass efficiency (number is national rank)

9. Taylor Kelly, Arizona State

17. Marcus Mariota, Oregon

Note: Big fall-off after these two. UCLA's Brett Hundley is 33rd, Oregon State's Sean Mannion is 50th and USC's Matt Barkley is 51st.

Rushing

4. Johnathan Franklin, UCLA, 146.45 yards per game

14. Stepfan Taylor, Stanford, 112.67 ypg

22. Ka'Deem Carey, Arizona, 105.75

26. Kenjon Barner, Oregon, 102.5

Note: Franklin came back down to earth against Oregon State, demonstrating the Beavers' run defense is for real.

Receiving yards

2. Marqise Lee, USC, 130.33 yards per game

3. Brandin Cooks, Oregon State, 127.5 ypg

5. Markus Wheaton, Oregon State, 118.5

24. Austin Hill, Arizona, 92.25

Note: Some big names -- Marquess Wilson, Keenan Allen, Robert Woods -- are missing. But both starting Oregon State receivers are here.

Sacks

2. Travis Long, Washington State, 6/1.63 per game

10. Anthony Barr, UCLA, 5/1.25 per game

10. Morgan Breslin, USC, 5/1.25 per game

10. Chidera Uzo-Diribe, Colorado, 5/1.25 per game

20. Leonard Williams, USC, 4/1.0 per game

Note: Williams is a true freshman defensive tackle and Breslin is a JC transfer. Barr converted to outside linebacker from running back/F-back in the spring. Appears to be a good move.
