If that is correct, then it's because they played Clemson in the ACCCG. Take out Clemson, and you don't have much. That's a legit argument because they play in a division that isn't very strong, and that's how they got to play Clemson.
They got to play Syracuse and BC from the other division and avoided Clemson, FSU, and Louisville in the regular season. They played ND, who was terrible. Use the eye test.
And the only reason our strength of schedule was close to theirs is because we played Alabama. You said the schedules weren't comparable, when in fact, they very much were.
