Agreed. Its 3 weekends of absolutely captivating sports drama.
With that said, I wouldn't be against the tourney re-seeding after each weekend. I don't think you could re-seed each round as it would require the whole region to be playing in the same location that weekend. That would probably be a nightmare trying to organize that many teams/games, and tickets for each program, and also practice accommodations as well.
Pod system as is now. The bracket would hold true for field of 64 and 32 games.....then re-seed and send them to their next regional destination.
Just for the hell of it the sweet 16 match-ups this year would have been....
South: Florida vs Dayton. UCLA vs Stanford
East: Virginia vs UCONN. ISU vs MSU
West: Arizona vs Baylor. Wisconsin vs San Diego St
Midwest: Michigan vs Kentucky. Louisville vs Tennessee
You decide if that's any better or worse than what we had.
