I've actually wondered this, but he made the call to be the play caller/D coordinator. He should know as well as anyone the time and energy it takes to do that. Frankly, he is out of excuses. This whole operation is of his design, he has had plenty of time to get the coaches he wants/needs. He makes the hiring decisions, he makes the game day roster, he designs the gameplans. This team should be humming and walking into the playoffs year after year and right now, the way this team is playing, I'm not sure they win another game
