I think Bo Ryan has said all teams should be in, though I'm not sure how he'd swing it. I'm all in favor of 96, as DH pointed out, many solid teams win conference and then lose in the tourney, finish 27-5, and somehow get left out. The ACC, Big Ten, and Big East's 9th and 10th place teams are usually better than many small conferences top team, and as George Mason proved, you can be a very good team getting hot at the right time, and make it a long way. It would also allow teams who had injuries, academic troubles, and such to sneak in as well.
