The only coach from Riley's staff who will be retained is offensive coordinator Norv Turner, who has three years left on his contract. Butler was noncommittal when asked if Turner would be considered for head coach.
Butler, Buffalo's GM from 1993-2000, has surrounded himself with former Bills players and front-office personnel. A possible replacement for Riley is Ted Cottrell, the New York Jets' defensive coordinator-assistant head coach. He was with the Bills from 1994-2000, the last three seasons as defensive coordinator.
