Buddy Nix will do personnel. The Bills have to move on from Fitz. I like him, but he just can't hit any med-deep routes, and all DC's are aware of it. If they get Andy Reid, a new QB, and a size receiver, then Chandler will be a great sleeper fantasy TE. Defense just needs a new coach and LB'ers.
The problem is that he may want to be in charge of personnel. He has had it here with the Eagles for over 10 years (he isnt very good at evaluating talent in the draft either). He seems to be a control freak. So I assume one of the factors in where he will go is if he would be in charge of player personnel.
