The ACC should have 2 divisions of 8 teams and require that you play the other 7 teams in your division (with each division champion based solely off these 7 games). Your other 5 games can be against any school you want. If you want to schedule teams from the other division, go ahead. If you want to schedule teams from outside the ACC, go ahead. Essentially this would make 2 mini conferences for ACC football and a 16 team conference for all other sports.
