Here's my bracket. Because of matchups, some of my surprise teams (up or down) don't really show up.
Belmont over Wisconsin killed me, but I went with the numbers and picked Belmont, even though I think the numbers are anomalous.
Reconsideration: That whole region troubles me. By the numbers I had BYU #8 overall but I kept pushing them down because of Davies' suspension. I had Belmont #7 and Pitt #9 - the former unexpectedly high, the latter much lower than most folks have them. So I chickened out and shaded both of those a few places. But I barely have the courage to keep Belmont at #11 (Wisconsin I have at #12). I could do half a dozen brackets with those variations, I suppose.
By the numbers, I have Belmont beating Wisconsin, Utah State, Pittsburgh, and BYU and going to the Final Four. Yet I am not convinced they could beat any of those teams, never mind all of them. The Southeast region is the weakest by far - or, if you prefer, the most equally competitive.
