Utah dropped 8 spots in the AP poll after their loss in Corvallis (9 in the Coaches poll), but they stayed in the top-25. They are joined by UW, Oregon, USC, WSU, and Oregon State. (If you hadn’t noticed, that is all 4 of the Pac-12 teams from the Pacific Northwest in the top 15.) UCLA is still getting votes in both the AP and the Coaches poll. And Colorado got a vote in the AP poll (but not the Coaches).
