WSU is going to go a long way in this tournament because of their defensive style and team play. The Pac Ten figured out the Cougars as the season went on, but the rest of the country is just getting their first look at the group from Pullman which gives them a significant advantage as the tourney shrinks to 16 remaining teams next week. The Cougars have been dominating in their first two games dispatching Winthrop, and Notre Dame by healthy margins.
UCLA, and Stanford will join the Coug's next week, and both of those teams have figured out how to handle WSU. I think it is conceivable that all three could make the final four since each team is in a different bracket.
