The obvious question is, if you're going to expand it, why stop at 76?
It's only going to hold for a mere handful of years until it inevitably gets expanded yet again, right? So what's all this pussyfooting around? Just open the floodgates, already. The ultimate goal is always to make more and more money by letting more teams in.....right? Go big or go home.
Make every double digit seed(10-16) play a play-in game. That's 28 extra teams to a field of 64 for 92 total teams. You're not in the top 92(essentially Top 100) you shouldn't be playing past the conference tournaments anyway.
That way, the dreaded 8/9 match-up really isn't so bad because at least you don't have to do a play-in.
Of course, if i had it my way, they would have realized it was absolutely perfect with 64 and never messed with it.
