To the bolded, and I am not saying I think this would happen. I am just saying how it would have to be done.Yeah they're not adding cannon fodder because they already have cannon fodder. Of course it's about money and adding the big brands. But they're also not losing the middle and lower tier programs, because they're needed to prop the big guys up.
What I'm saying is that I don't see any kind of "superconference" happening where it's comprised entirely of bluebloods and elite brands, because once that happens, over half of those programs will no longer be bluebloods or elite brands. There are just as many L's to go around in conference play as there are W's.
It would have to be set up like the NFL, with a commissioner, player's union, CBA, equal everything, etc. The NFL is set up for every team to be .500, and yes it doesn't work that way because franchise's can't get out of their own way with poor leadership, drafting, trades, contracts, etc. But that's the crux of it. They try and make it so the teams that finish poorly get better draft opportunities and schedules to improve their team and situation.
With the legal stuff around athlete's being paid and all of that, it's not like it isn't feasible. Not sure what happens, but there is a way to keep everyone a brand of some sort.
