Inevitably, a new division of CFB is created, with two conferences. It's the NFC and AFC. The BIG10 and SEC might continue to poach a few additional programs (Washington, Oregon, etc.) but the majority of leftovers from the BIG12 and ACC will be relegated to join the MWC, CUSA, MAC in "Division 1B".
They are gonna milk this cash cow dry. People in power are short-sighted if they can't recognize WHY CFB is so popular, and throw all that aside for the immediate money that will diminish over time.
