We also played a FCS team, two of the worst FBS teams, and a 6-6 ACC team.
Also when you look at our SEC opponents, Vandy lost to Georgia State, Kentucky lost to Louisville, Florida lost to Miami, Arkansas lost to Oklahoma State, Mississippi State lost to both Arizona State and Toledo. So it’s not like we played a bunch of teams that beat up on everyone else and just got cannibalized in the SEC.
According to the SOS metric on Sports Reference, we had the 68th strongest schedule, which sounds a bit more realistic than whatever metric you are using.
