It was pretty clear after last week that there were three teams separating themselves from the rest of the conference.
One week later, and zero losses between those three teams, that gap feels a bit larger, even if the actual standings don't show that just yet.
With six voters this week, and giving one point for 1st place votes, two points for 2nd and so on, here are our Pac-12 Power Rankings with just four weeks left in the regular season:
| Rank (change from last week's ranking) | Team (Pac-12 record) | Points |
| 1 (0) | Oregon Ducks (9-2) | 7 |
| 2 (+1) | Arizona Wildcats (7-4) | 12 |
| 3 (-1) | USC Trojans (7-3) | 17 |
| 4 (0) | Utah Utes (6-5) | 32 |
| 5 (0) | Colorado Buffaloes (6-5) | 33 |
| 6 (0) | Washington Huskies (7-4) | 35 |
| 7 (-1) | California Golden Bears (5-5) | 39 |
| 8 (0) | UCLA Bruins (4-6) | 47 |
| 9 (0) | Oregon State Beavers (5-6) | 49 |
| 10 (-1) | Stanford Cardinal (4-6) | 60 |
| 11 (0) | Arizona State Sun Devils (3-8) | 65 |
| 12 (0) | Washington State Cougars (1-10) | 72 |
As you can see, the middle of the group is pretty much interchangeable, with just seven points separating 4-7.
