The "tell" will be who the #1s play in Round of 64
If they expand to 96, the thing I'll be most curious about is who the #1 seeds will get in their first game (Round of 64). Will it be the winner of a #16 vs. #17 game (as it should be), or will they simply lump together the bottom 8 teams in the field (#23 & #24s) and have them play for the right to play the #1s in each region? So each region would have a #1 vs. #23-24 winner, #2 vs. #21-22 winner, #3 vs. #19-20 winner, and so on, all the way down to #8 vs. #9-10 winner.
If they do that, instead of feeding into the Round of 64 the way they should (#9 vs. #24, #10 vs. #23, #11 vs. #22, etc.), then we'll know the expansion was all about the big boys in every single way, shape & form. The big boys (top seeds) will want their "gimme'" in their first game. They certainly won't want to play a #16 or #17 in their first game (Round of 64). Odds are a #16 or #17 would be a reasonably decent opponent, someone the likes of a UConn, Dayton, Illinois or North Carolina from this season. ... underachievers, but a lot more talented and dangerous than the Arkansas-Pine Bluffs, Winthrops and Lehighs of the world.
