Another thing that's clear is Cignetti runs a conservative, ball-control offense, or at least he did at Rutgers. He's not running the offense in St. Louis, but he working for an offensive coordinator who is on the record as stating a preference for the running game and making the play action a big part of the offensive game plan.
At Rutgers, Cignetti worked with the quarterbacks, but he also ran the entire offense, something else to consider when looking at his track record there.
