I watch St. Mary's play quite a bit since I'm a Gonzaga alum and fan, but also a huge Gophers fan and their main players are definitely their big guy Brad Waldow and guard Stephen Holt. Waldow is a big physical player who has a nice touch around the basket, but he is not overly athletic. Holt is a really solid player all-around and is a good shooter, but I think our guards can definitely give him trouble. Beyond that it is basically James Walker III, Beau Levesque and Kerry Carter who provide any scoring, they can all hit the 3 ball but they have struggled for the most part when playing the top WCC teams like BYU and Gonzaga.
Like damueller99 mentioned this is definitely not the St. Mary's team from last year, it is a rebuilding year for them after losing their star Matthew Dellavadova whose now playing for the Cleveland Cavaliers. Next year they should be better with Waldow returning, a Stanford graduate transfer available in PG Aaron Bright, a could solid freshman and I expect Joe Coleman to play well for them. The Gophers should win, but SMC could give them trouble if they don't bring their A game.
