If we assume that the last at-large teams into the Big Dance are the 10, 11, and 12 seeds not to win their conference tourneys, we have the following teams (and their first round results):
Michigan (won over Clemson)
Maryland (won over Cal)
Minnesota (lost to Texas)
Dayton (won over West Virginia)
Zona (possibly the LAST team in, won over Utah)
Wisconsin (possibly the SECOND TO LAST team in, won over FSU)
So what we have here is 5 out of the last 6 at-large teams into the tourney advancing to the Second Round. Guess the committee got the lower at-large seeds right and over-valued some of the high at-large bids.
