With all the talk of Pettine being interviewed by the Browns, has anyone noticed that the Bills have hired a defensive asst.? Is there some hidden agenda or impending departure being written on the walls? Or is the organization trying to find an apprentice for when Pettine eventually leaves? Or better yet: am I just paranoid and the asst. will pan out as an insignificant low level coach? Anyone have a theory? Am I the only one who has noticed?
