You don't want him, trust me. I suppose it is possible that he regains some form of productivity, but one thing that stood out to me with the Eagles were his incredibly poor ball skills. When a ball is thrown up for grabs and he is in coverage he gets totally lost. He has no idea how to adjust and make a play on the ball, he gets out-muscled by receivers, and gets turned around and confused. He was always out of position to make a play. Letting a receiver post him up and you see him make a futile effort to try to knock the ball away. He was oafy as all get out.
To make matters worse, he looks like he is running in mud when the receivers are running on turf. He looks a step slow on every play, and even his tackling left much to be desired. He whiffed on too many tackles for my liking, and even let the ball carrier drag him yards down field when he did wrap up.
I personally think he is totally shot, but stranger things have happened than a player regaining success.
