You guys, after the next realignment, the playoff will be Big Ten vs. SEC. It'll be the NFL model. 6 or 8 teams from each conference make the playoff. The conference champions play for the natty.
The writing is clearly on the wall. The Big 12 and ACC schools, along with Notre Dame, are figuring out how to get accepted by either the Big Ten or SEC.
The leftovers will be completely left out. They won't have the money to compete or pay players like the Big Ten and SEC.
I actually think the SEC and Big Ten will stop at 20, not 24 teams. The ACC and Big 12 don't have enough schools that grow the pie for the rest of the conference.
The Big Ten will take Norte Dame and one of Miami, FSU, or UNC. The hardest pick of those 3 would be UNC due to state politics with their universities. I suppose you could look at SMU, Houston, and GT, but some of those schools will head to the SEC. To get to 24 you'd add Norte Dame, plus 5 of the other 6. Plausible because of their markets and their need to join a Power 2 conference but unlikely to get 6 of those 7.
They won't add just to add. They'll want helmet schools, big markets, and schools where the conference doesn't have a flag planted like Texas and Florida in order to grow the pie and per school payout.
You play your full division, another division, plus the same place teams that finished in your school's position the previous year. That's an 11 game conference schedule. The division winners plus 2 wildcards go to the Big Ten playoff. The winner plays the SEC champ for the natty.
That hypothetical conference with 11 conference game seasons and a full slate of Big Ten playoff games would probably be worth at least $3 billion per year by the next agreement. That's $150 million per school at 20 teams.
