This is the same man who turned one of the last ranked offenses (Dallas 1990) into a show time dynasty starring Troy Aikman, Emmitt Smith, Michael Irvin that won three Super Bowls in four years (’92, ’93, ’95). Though successful as an offensive coordinator, head coaching did not suit his fancy. As the head coach for the Redskins, Raiders, and Chargers he did nothing ingenious. He's proven time and time again that he's better suited as a coordinator.
