The Big12 is like the MLB and P2 is like the NFL. It's a good conference that will have strong regional fans but nationally wont move the needle. Plus from a conference map, they have flagship universities and built in rivalries. The ACC has a few power names, but when they leave, the ACC wont have those same regional fans for football (they will for basketball), and no in-state rivalries. So once FSU/UNC say good bye, the ACC will be in 4th place by a mile.
