that's whats holding them back.
i'll take this a step further saying that for the good of the game, they should get rid of all the AQs, except the Ivy leage and ACC.
This will force teams like Navy, Towson, and all other teams who are on the brink, but in weak leagues, to get harder opponents and step up their game. Also, the quality of teams in the tournament will go up, leading to closer games and more upsets.
