I will be shocked and appalled if the 8 game conference schedule is retained beyond 2025. It would be truly absurd to see a chest-pounding so-called super conference that wants to play OOC 1/3 of the time.
Because not everyone has 3 true rivals that should be played every year, my format preference would be 2 permanent rivals for each team, with a third semi-permanent rival that is reviewed and potentially changed every decade or so. The review would be based on a considerations including performance trajectory (with the aim of avoiding anyone having 3 world-beater or cream-puff rivals) and whether both teams want to continue playing annually. Anyone who wants to maintain their semi-permanent rival (for instance because they're a true rival, such as Arky for us) could waive such review.
