Are you serious? Imagine a conference that existed outside the NCAA that contained the likes of, say, Texas, Alabama, Notre Dame, Penn State, Ohio State, Southern Cal, Florida, LSU, Oklahoma and Nebraska.
You want to pay players? No problem. Scholarship limit? None. You want to have a TV contract that rivals the NFL? Great. You want to ensure that there’s no revenue sharing with crap bottom-feeder schools like Minnesota or Baylor? Check.
The NFL-sized revenues would be a pretty nice benefit.
You have to ask yourself, why haven’t they done that? The reason is that there must be a financial benefit for being a member of the NCAA. What you are proposing is in effect an alternative professional league. What is the track record of those leagues? Not good. The NFL would see you as competition and either crush you or assimilate you as a professional minor league and eliminate your school affiliation.
