I think Colorado was the only first-round (real style, not newspeak) team to win.
As it turned out, the only team that truly bombed out of the NCAAs was UCLA, and they suffered a major injury in the conference tournament. The Pac 12 did much better than the Mountain West, in particular.
but slotted them down to 12s for geography or bracketing principles or something. Looks like 11 was way too low as well.
