We need to play FSU every year, the ACC needs us to play FSU every year, and FSU, with their attendance issues, pretty much needs us to play every year. So we can put this **** to bed right now.
However, 'Cuse raises a valid point, and the elephant in the room remains schedule inequality in these new bigger conferences. Basically, because of these cross divisional 'rivalries', you're gonna make the path to the championship game much more difficult for one school than another, all in the name of 'rivalries', some of which are forced.
Easy thing to do would be to go to a 9 game conference schedule with one set 'rival' and 2 rotating opponents, or make cross-divisional games not count unless in need if a tie breaker. In other words, if we go 6-0 in division but lose to Clemson and FSU, and Virginia Tech goes 5-1 in the division but beats B.C. and Wake Forest, we'd still win 'the division'.
Either that, or arrange the god**** divisions in a better way, and keep the teams you want to play 'together' (unfortunately, you probably couldn't do North/South, as cool as it would be). Maybe something like:
Miami, FSU, GA Tech, Louisville, Pitt, Syracuse, BC
Clemson, Virginia Tech, North Carolina, NC State, Wake, Duke, Virginia
For example, the only regional 'rivalry' you'd lose on a yearly basis here is Clemson-GT and your divisions would remain sort of balanced.
