Random postseason thought with the discussion of expanding the tourney.
32 conferences. Change all conference tournaments to top 4 only, at the home court of the #1 seed. 4 day tournament, with best of 3 semifinals, and a single game elimination.
Then the NCAA tournament is a 48 team tournament of the 16 best conference champions, plus the 16 other conference champions and the 16 best runners up. First weekend is a best of 3 series of those 16 runners up at the 16 worst conference champs. That gets you to 48.
4, 12 team, single elimination regionals to get a Final 4
