because Torvik makes it easy, here are the teams sorted by NCAA tourney wins from 2000 until now...
MSU: 46 wins (also 12 Sweet 16, 7 FF, 1 title)
Wisconsin: 33 wins (10 Sweet 16, 3 FF)
OSU: 22 wins (5 Sweet 16, 2 FF)
Maryland: 21 wins (4 Sweet 16, 1 FF, 1 title)
Michigan: 19 wins (5 Sweet 16, 2 FF)
Purdue: 19 wins (6 Sweet 16)
Illinois: 17 wins (4 Sweet 16, 1 FF)
Indiana: 14 wins (4 Sweet 16, 1 FF)
No other conference team with more than 4 wins over that time frame and only 1 other S16 appearance (PSU) combined.
Those same schools with their number of conference titles
MSU: 8
Wisconsin: 5
OSU: 5
Maryland: 1
Michigan: 2
Purdue: 3
Illinois: 4
Indiana: 3
The other schools have 0 combined titles in that time frame.
If you ask me...
#1 MSU
#2 Wisconsin
#3 OSU
then gets a little jumbled with some others. Where Maryland fits exactly depends on if you give them any credit for ACC accomplishments in that time frame including their 2002 national title.
