When it came to building his staff of assistants, Chiefs coach Andy Reid went mostly with guys he knew. But for a most important hire, defensive coordinator, Reid went with a veteran coach he has never worked with.

Bob Sutton, 61, is the new defensive coordinator. Sutton was for nine seasons the head coach at Army, where he had a record of 44-55-1, and spent the last 13 seasons with the New York Jets, including three as defensive coordinator.

The Chiefs will probably continue to use the 3-4 system, though Sutton has also coached the 4-3.

Otherwise, six coaches hired by the Chiefs on Friday have ties to Reid from his 14 seasons as head coach of the Philadelphia Eagles. Offensive coordinator Doug Pederson both played quarterback and coached for Reid with the Eagles. Running backs coach Eric Bieniemy, a former University of Colorado star rusher, played for Reid.
