The NABC has discussed it. And I don't think it's just a ploy to get Mizzou in. How would 80 teams work, you ask?
80 - 64 = 16 extra teams.
There are four brackets, so I would assume there would be 4 new teams per bracket, the 17th, 18th, 19th and 20th seeds. I don't think it would be at all fair to have these guys battle it out in two games each to make the actual tourney, so I'm guessing that they would do battle with the 16, 15, 14 and 13 seeds respectively for the honor of getting to play one of the top 4 seeds in what used to be the first round.
They might play all of the games at one location, effectively adding four new first round locations.
I'm all for more excitement, but this just seems a little paunchy to me.
Anybody else have any thoughts? Am I putting this thing together wrong?
