Through 2012, only Arizona (1997) won the championship as a #4 seed. (There were no seeds prior to the 1979 tournament.)
As of now, there are 65 teams in the tournament. Two teams (generally considered to be the worst in the tournament) play an "opening round" game. The winner gets the fourth 16 seed in the first round of the tournament.
They have made it to the tournament 43 times. And they have won 11 of the NCAA tournament championships.
