If we are dreaming about four teams coming the the B12, screw anyone that is currently available. Give me FSU, Clemson, Louisville and Notre Dame. FSU and Clemson can't get in the SEC, as they don't help the SEC much as the SEC already has South Carolina and Florida. Notre Dame probably would never go to either the SEC or B1G if it was forced to join a conference. Louisville really should be the B12 already we were stupid not to grab TCU in my opinion. Should have added Louisville to be a travel partner with WVU, also boosted our Eastern reach.
Those are just Four I would want, and the only one I can really say that is questionable is Louisville. But Virginia would rather been in the B1G, VA Tech Seems more SEC, Pitt doesn't do anything for me. UNC, Duke and NC State probably all stay together because they care more about basketball than football. I suppose you could make an argument about Georgia Tech but my guess is the B1G would want them. Maybe you if you can you grab Miami and GT Or one of the North Carolina schools if they don't want to stay in a basketball conference, and get 6 additional teams.
Anyway this will never happen. I am pretty sure OU and Texas have decided they will hold the B12 hostage until the grant of rights runs out or doesn't hold any weight and they will either run together somewhere or run their separate ways.
Really, I wish we would just all figure out that College sports are on their last legs, and more than likely within my lifetime, they will ceases to exist like they currently do. A move that makes major college athletics a minor league system for the NFL and NBA is probably more likely than the B12 surviving past 2024.
