Since the SEC is adopting a nine-game model, probably using a 3-6-6 format, the ACC will probably switch to a nine-game model as well. So let’s take a look at 9 game models. As we all know, there are two constraints: 1) The ACC has 17 football schools. 2) UNC needs to maintain three primary rivals. Here’s one solution I can think of: let every school have two primary rivals and play a 2-7-7 schedule, except for UNC and NC State, which will have three primary rivals and play 10 conference games every other year. For example, in odd years, UNC plays 10 conference games, and in even years, NC State plays 10 conference games. Does this make sense? Please let me know if the math doesn’t work. I’m a Pamplin graduate. Assuming the math works, here is my pairing for primary rivals: UNC: NC State, Duke, UVa NC State: UNC, WF, GT Duke: UNC, WF WF: Duke, NC State UVa: VT, UNC VT: UVa, Miami Miami: VT, FSU FSU: Miami, Clemson Clemson: FSU, GT GT: Clemson, NC State Stan: Cal, SMU Cal: Stan, SMU SMU: Stan, Cal Cuse: BC, Pitt Pitt: Cuse, Louisville BC: Cuse, Louisville Louisville: Pitt, BC What do you think? Everyone has at least two primary rivals and plays everyone else every other year.
