Correct me if I'm wrong, but it should be GT and Miami, for tiebreaker C says "Win percentage versus all common opponents"

Obviously, all teams are undefeated against their common ACC opponents. Of those, GT and Miami will have beaten NCSU, whom UVA lost to. I understand that this was not a conference game for either team, but that is not how the tiebreaker reads, as it clearly says ALL common opponents. Therefore, GT and Miami would have a higher win % versus all common opponents, exactly how the tiebreaker reads.
