The problem with the super conference idea is that a lot of schools that think they should be in the club are either going to get left out or traditional relationships are going to make it too bloated to ever be effective.
The pro model is based on having teams in the largest metropolitan areas to maximize local revenue. The college model is going to have to ignore schools in those cities in favor of traditional powers in the general vicinity. It also has to hope that oversaturation in certain areas while ignoring large swaths of the country doesn’t kill any goodwill that has been built up over the last century plus.
I can come up with 18 sure things for the super conference and probably another dozen that consider themselves blue bloods but would just be duplication in a national model. i.e., if you’ve got Michigan, Michigan State becomes superfluous. If you’ve got Georgia, Florida State and Alabama, do you really need Auburn? Not to mention that Clemson, Georgia, Alabama and Florida State essentially all have Atlanta as their hub city so why include all 4 other than they’ve been ranked a lot in the past while Georgia Tech is located in Atlanta?
There’s going to be a lot of schools that feel like Oregon State and Washington State do right now. Been part of the club for decades and realize too late that they were only there as long as they were necessary for the cool kids advancement.
