The NCAA may expand the NCAA tournament to over 90 schools by 24/25

[Hi-Low]

With the current system, where conference tourney Champs get an automatic bid, essentially no team is eliminated until they lose in their conference tournament. Kind of makes the regular season irrelevant.

Not really...you could make that argument for 1 bid conferences but not for multi-bid confernces. Especially the top 8 or 9 conferences where most of the at-large bids come from, the regular season is very important. In the power confernces it's rare for a school that has a lousy regular season to win 4 or 5 games in the conference tourney...it happens (G'Town) but rare. You're also going to get a better seed if you have a good regular season, conference tournies don't have great impact on seeding.
