San Francisco--7-0--Nothing especially noteworthy about the teams they've beaten
Gonzaga--8-1--Beat Oregon in OT, then got blown out by Michigan in preseason tournament
Santa Clara--7-1--Beat Washington State. Blown out by Stanford.
St Marys--7-1--Beat Wisconsin in OT at a neutral site. Beat Utah State at home. Lost to Winthrop at home (head-scratcher for sure)
Portland--5-1--Lost to Utah State by 10.
Pacific--7-3--Lost to South Dakota, at Hawaii, and to Boise State in triple OT
BYU--5-3--Lost to San Diego State (8-0 with wins over Iowa, Creighton, San Diego), Boise St in OT (4-2), and Kansas (6-1 lost by 2 vs Duke). Wins at Houston, and vs UCLA and Virginia Tech in Maui.
In my opinion, looks like Gonzaga and St Marys will, again, be very good. BYU looks to be improved, especially when Yoeli comes back. Some other WCC teams look to be improved, but I don't see them seriously challenging the Zags, SMC, or BYU.
