Here is is my fundamental point. I don't want weaker teams getting in simply because they won their conference. Obviously that is not an issue with the B10 and SEC. If you go to 16 that won't be an issue with the B12 and ACC champ either. Where I have the issue are all the other conferences and this G5 requirement. Bogus. That is why it is cleaner in my mind instead of saying the conf champs from the Power 4 are auto qualifiers and no one else just say no one is an auto qualifier and they are all "invited" in.
College basketball is unique. If they went to just a 16 team format with no auto qualifiers it would end up being whatever your top 16 are today in the rankings or at the end of the season. That would be a terrible model to adopt for college basketball. I get that. College football is different. You can't have 68 teams or whatever it is. The # of playoff spots is limited or "precious". So you need to get to the top 16 in the country.
With all due respect, your fundamental point sucks, and is the antithesis of true athletic competition. You want a beauty pageant that works in an exclusionary way, to increase the barriers to competition for all but a select few.
If you want that, then formally break free from the rest of the teams.
