Those philosophical differences between the SEC and the alliance could be huge. We'll see as we go along. This could lead to a split between the SEC and everyone else. It probably won't happen, but if it did, that could split college athletics int two factions, and the lesser schools, not in these four conferences, would have to decide which way they want to go.
Just guessing here, but the vast majority would probably have to side with the alliance, because they would never be anything but patsies to the SEC if they played them, and never financially capable of competing against the alliance.
All just conjecture. Shooting from the hip.
