Fact is we only had one win against a tournament team. Every team that made the tournament had at least a handful of them. It sucks that our opportunities against Purdue, Michigan State, and Ohio State didn't come at home, but most every at-large team has a win of that caliber on their resume. 13-5 is nice and all, but we racked up wins against average to below average teams.
My only gripe is that teams that have faltered down the stretch (Oklahoma, Arizona State) maybe shouldn't get in. But actually, if you look back at past tournaments, how you finish your season really doesn't have any correlation with how you do in the NCAA tournament. And to be honest, if we played Oklahoma's schedule, we might not have done any better. The Big XII isn't full of world beaters, but everyone but Iowa State is at the very least a solid team. We'd be underdogs if we played any of them on the road.
