Those wins aren't worthless, and they didn't all come against Big East teams. Who cares about Loyola Marymount, true. But Butler beat UNC, PC beat Notre Dame, etc. Gonzaga and Nova were roughly equal. And the BE stuck 5 teams in between the next best WCC team.
I can take your point that they were probably the weakest 1 seed (I'd pick Duke/Wiscy/Virginia (pre-injury)/Arizona/UK) ahead of them. I'd put them ahead of the Zags and ahead of Kansas, and then all the 3 seeds.
The Big East was overrated in the metrics the selection committee uses. And even then, they found a way to over-seed a number of teams (Georgetown, PC). But as long as the metrics stay the same (they will) we'll see this yearly, and we need the AAC to start gaming the system the same way.
