I think its the D line and the linebackers. There is only one player on that line whose job is safe- JPP. No other player has proved that he is adding value on a consistent basis. The LBS are playing very poorly as well. Cincinnati ran the ball straight down our throats, right between the tackles. It was hard to watch. It's obvious we need to get some more stout run support, especailly up the middle at DT. All season they have been getting blown off the ball.
