It would be easier to say with a straight face that we deserved a 4 seed if I had any idea what they were basing the seeds on. According to KenPom, yes we were better. Sure, we lost to Butler, but Iowa State has a better KenPom ranking than us, we beat them on the road, and they got a 5 and we got a 6, so they must not have paid too much attention to head to head.
Duke's OOC SOS was 102, FSU was 120, UCLA was 286(!). Those teams got a 2 seed and a 3 seed. Purdue was 163, WVU was 261, Notre Dame was 189 and those are 4 and 5 seeds. UC's was 34.
Looking at those numbers, what, realistically, could UC have done to get a higher seed? Give them a perfect conference record and tournament title and that makes them 32-2, but doesn't change their overall SOS and adds two top 25 wins and one top 100 win (assuming 3 losses to SMU wouldn't drop them from the top 25 RPI). Would 4 top 25 RPI wins be enough to get a top 4 seed? I really don't know.
This probably sounds more whiny than intended, but my biggest issue with the committee is they seemingly used different metrics for different teams based on where they wanted to put them and what would generate the most interest.
