Well who from the Big East would you have not allowed in the tournament this year? Marquette is the only one that probably didn't deserve to go and they ended up making the Sweet 16.
Since 2003...
SEC-has 2 National Champs and 4 Final Four Teams during that span
BIG TEN-has 0 National Champs and 5 Final Four Teams
ACC-has 3 National Champs and 5 Final Four Teams (only one team wasn't UNC or Duke)
PAC 10-has 0 National Champs and 3 Final Four Teams (all UCLA)
BIG 12-has 1 National Champ and 4 Final Four Teams
BIG EAST-has 3 National Champs 9 Final Four Teams
I don't question that they have a few good teams year in and year out. My point is that they didn't deserve 11 teams this year. I would have left out the last 6.
