And every 5th year you could rotate the 3 permanent teams as well. It's so simple like someone posted it will never happen.
I wouldn't set it up like Alsacs did. Your 3 permanents should be 1 northern partner, 1 mid states, and 1 southern state partner so for SU it could be for first 4 years - BC, Wake & Miami. Second 4 years - Pitt, VT & GT. Etc, etc, etc.
The way I set it up wouldn't benefit us, but honestly our demands are low on the priority of the ACC and would likely be the template the ACC would follow.
UNC has to play UVA, NC State, Duke
UVA has to play UNC and VPI
NC State has to play Clemson, Wake, and UNC
Duke has to play Georgia Tech, UNC, and Wake
Clemson has to play Georgia Tech, Florida State, and NC State
Florida State has to play Miami, Clemson and wants Georgia Tech annually.
Miami has to play Virginia Tech and Florida State
Georgia Tech has to play Duke and Clemson
Wake has to play NC State and Duke
Virginia Tech has to play UVA and Miami
Pitt, BC, Syracuse, Louisville have no juice.
Most teams have two rivals easily. I just configured it in a way for TV matchups and what I think would happen. I would love SU to get Miami annually, but TV would likely want Louisville v. Miami if possible.
