Not sure what a Sr. Defensive Assistant does.
Seriously though. Outside of the Eagles and Bucs game, I can't think of one thing he did well. Couldn't stop the run. Couldn't slow down the passing game. Couldn't get off the field. He could have put eleven in the box to stop the run and I would have been happy that he did something. And he kept running fat arse Ellis out there until week 15 when Hicks was outplaying him. Hell, Thomas or whatever his name was out playing him.
