Can't swear it, but I think Pete Carroll had a total of 3 seasons in 2 failed stints before USC and then the SeaChickens.
He made the playoffs twice with the Pats and had a 33-31 record as head coach in 4 seasons before heading to USC.
But Rodgers leads the league in frumpy expressions and negative body language on the sideline, which makes him, like Josh Allen, a unique double threat.
