Good luck to him if he is to be named a NFL head coach. Only 32 such positions. Can remember years ago had friend drafted and made starting roster of the Kansas City Scouts. Recall him telling me he had made the NHL , it only the Kansas City Scouts, my response , he had made the big show, he having a position millions would kill for. I believe it so with Pettine. Seems to many when a player coach leave team the process begins to beat him down. Unfortunate. Good luck to him.
(that a man on Bills staff considered for head coaching position does speak well for Bills selecting such people)
