Right now we are in a pause about the future of college football, the powers that be are trying to figure out which way to go.
Do they go with 30 to 40 team super conference built around the SEC and Big 10, if they go down that path, they start with 30 teams, add ND, USC, Clemson, Florida St., Oregon and you are at 35 and still have Washington, NC, Stanford, UCLA and many other teams wanting those last 5 spots. No way if they chose this path are they going to take a every team in both the Big 10 and SEC. Way to many Rutgers, Maryland and Illinois get their way into the league, leaving out better teams.
The other path, the one I think they will chose is to bring all the conferences up to 16, adding the best of the rest to the current conferences and then breaking away from the NCAA.
If they go down the first path, they run the issue with leaving large blocks of the country not caring about college football because their team is not in the highest level.
I guess we will find out in the next 2 to 4 years. Which is fine.
