Look at who GU schedules in their OOC, especially this year. They don't avoid competition.
And the Pac 12 hasn't come calling so it doesn't really matter. And they play and beat the PAC in OOC games anyway. Last year they beat Oregon, Arizona and Washington. This year they were supposed to play UW, Arizona and USC in OOC.
Would I like to see them play in the PAC? Yes. I'm a huge PAC fan and would love to see GU add some relevance to that conference. Is the in conference play boring? Yes and I think it does hurt them come tournament time. The teams that hurt Gonzaga are the teams that are super athletic and you don't get that in the WCC.
But like I said, the WCC is improving. I think it is safe to say that St. Mary's and BYU will be tournament contenders most years. USF has been a very solid mid-major team and good things are happening at LMU and Pepperdine. Again, not saying that the WCC is a great conference. But it's a mid major conference that was going to get 3 teams in last year.
Gonzaga has made the most out of what has been offered them at this point, and that's all that you can ask for.
