IMO, Muschamp meddled too much in the offensive schemes and identities too much, for the sake of his defenses. I think he did this while HC at Florida - this was a huge gripe from the Gator fanbase when Muschamp left. I always gave him the benefit of the doubt due to having different OCs almost every year at UF, and then they had a rash of OL injuries as well. But the UF fanbase always said "no", that he pushed the offenses to having 3 yards and a cloud of dust, to stay on the field and own the time of possession every game, to keep his defenses off the field as much as possible. He felt that as long as his defenses can keep scores down, then they'd win games, often to an extreme of one-dimensioning his offense's ability to move the ball, attack the red zone and score points.They even developed while here during CWM era. The problem was that Muschamp could not make in-game adjustment and his coordinators did not believe in counter plays or pre-snap deception on either side of the ball. He got outcoached nearly every week and once teams figured out what we would try to do and what we could do, they adjusted while our coaches just shrugged.
When our own offense struggled every season under Muschamp, those UF fans said, "See? Just like with us!". Only, our own defenses never did much either during CWM's time here, so it was doubly bad for us.......
