The upsets in the last 4 Tourneys that I listed in my earlier post would seem to show otherwise with regards to talent gap in the NIL era. Other than this Tourney, the last 4 since NIL have featured major upsets where much lower seeds took down a big dog. And that was for 4 Tourneys straight leading to this year's which has been largely chalky.
I can't remember any Tournament stretch in the past where those types of upsets occurred that often in consecutive years. 1's, 2's & 3's losing used to be incredibly rare. Now it happens fairly often. That would seem to indicate more parity across all of college hoops.
And a bonus to more 15's beating 2's for ISU fans is that hopefully we'll never have to see the clip of the Hampton coach celebrating after that loss ever again!
