According to Brett McMurphy, it sounds like B1G teams will no longer have to play a P5 OOC opponent every season starting in 2024. That also happens to be when USC and UCLA join the league and the playoffs get expanded to 12 teams. Will be interesting to see if Maryland adjusts any future OOC games accordingly. They have OOC P5 games on the books through 2031.
