It makes perfect sense for the B1G to grab Notre Dame, GT, UNC, Duke, Virginia, Stanford, Oregon, and Washington and get to 24 teams.
It makes sense for Miami, FSU, Clemson, Va Tech, and NC State to go to the SEC. That's 21 teams so one of them may get left out or more may be added depending on our love for round numbers.
It makes sense for Arizona, ASU, Utah, and Colorado to join the rest of the Big 12 and become the Big 16.
That would leave Cal, Washington State, Oregon State, BC, Syracuse, Pittsburgh, Louisville, and Wake Forest possibly begging the Big 12 to become the Big 24.
Notre Dame can get permanent conference opponents from the group of USC, Stanford, Georgia Tech, Michigan, Michigan State, and Purdue. Navy is the only game they would need to save for out of conference.
