That's something that fair or not can't be a coincidence, especially when the ACC is doing the scheduling.
From an April 2019 SI article previously mentioned here:
Within the Power 5, two conferences have made FCS opponents a regular feature of their schedules. According to STATS Inc., since 2010, the ACC has played 131 FCS opponents, the SEC 130. Meanwhile, Pac-12 teams have played 74 FCS teams, followed by the Big 12 with 69 and the Big Ten with 65. In 2014, the Big Ten tried to remove FCS games from its teams’ schedules, only to reverse course two years later when no other conferences followed suit and filling out a full slate proved difficult. The Big Ten still has the most restrictive rules pertaining to FCS scheduling, and commissioner Jim Delany’s experiment earlier this decade proves how tough it would be to completely remove those games from the ledger.
