To make such a list, you have to first decide what will prompt the much speculate move to four 16-team super conferences. I think it will happen because Texas decides to become an independent or because another team, like Texas A&M, leaves the Big 12. Either way, the Big 12 will crumble and other conferences will feast on what’s left.
It’s my belief that the end of the Big 12 signals the end of the Big East. The SEC, Big Ten and Pac-12 will gobble up the best teams from the Big 12 quickly. The ACC will struggle to keep up. Most of the conferences will have to look outside the Big 12 to get to 16 teams, so they’ll pick apart the next weakest conference, the Big East. However, I don’t believe the SEC, Big Ten, Pac-12 or ACC will raid one another.
