Gonzaga actually had as many Quad 1 victories last year as Baylor.
Also, the WCC isn't that bad this year. Currently 4 teams in the top 50. That's 8 games against top 50 opponents right there (counting 2 WCC Tourney games). Don't forget about Texas Tech. So, 13/32 games are top 50 matchups (40.6%). 12 of the 18 WCC games are against top 100 opponents.
Yes, it obviously isn't as challenging as the Big Ten or Big 12. But given they're playing against small Jesuit schools, it's about as good as a schedule as they could hope for. I personally think they lose at least 1 WCC games this year.
