Cross-division rivalries are a mess. In addition to the imbalance of playing Clemson every year vs. playing Wake Forest every year, it also results in a scenario where rarely play other ACC teams. There's only 1 slot for non-rival Atlantic teams, so you play them once every 6 years. That means you visit them once every 12 years. So if you're a Tech Alumni who just moved to Louisville, and really want to go to a GT game in Louisville, the next game will be in 2030. There's a better chance that the ACC will disband, realign, reschedule, or add teams before that game takes place.
