I would give DJ a C for this year. I think he did a pretty good job and the team as a whole exeded expectations and were competetive. He does need to improve on his decision making and time management though. One negative decision that really sticks out, is the 4th down against Tennessee. Not that he didn't decide to attempt a FG, but that he had to ask RL if he was comfortable from that distance after the 3rd down play while the play clock was ticking. If I am the head coach, I approach RL before the Titans even kick off to see where RL is comfortabe and manage that drive to at least get to that spot. By the time the decision not to kick was made the play clock was winding down and JP had to rush the snap and throw up a prayer. Hopefully he will continue to grow with this team and impove along with them, obviously the Bills cannot afford to start over again. I am fairly confident that he can make the improvements and adjustments that are necessary to some day be a very good coach.
Go Bills....
