Dons always seem to give the Zags a tough game. We've been snakebit several times at USF over the past fifteen years.
WCC looks to have 4-5 solid teams in addition to Gonzaga this year: USF, BYU, St. Mary's, Pepperdine, Pacific...off the top of my head.
After watching the Zags' first two games, I just don't see how they don't go undefeated in WCC. Main reason is there won't be any "road games", it'll be like every game is on a neutral court. Last year, the BYU home crowd willed their team to victory...18,000 crazy fans. They won't have that home court advantage this year.
Zags are stacked this year. Depth could be a problem, maybe.
