After beating SMC on 2/13, the 3rd spot was clearly Pepperdine's to lose...they were 3-0 against other contenders and had the win over BYU. But, I think they lose it to SMC or LMU.

But, regardless of the WCC tournament seeding, the games to see who plays Gonzaga and BYU will be exciting and competitive. Any of the contenders could make it into the semifinals.
