Aaron Williams is among several starting Bills defenders that are playing for a defensive-minded head coach for the first time at the NFL level.
Any Buffalo Bills defender that has joined the team since the end of the 2010 season has yet to enjoy consecutive years in Buffalo in which they have played for the same defensive coordinator, nor with a head coach that cut his teeth on the defensive side of the ball.
Starting safety Aaron Williams is among that group; he has played for head coaches Chan Gailey and Doug Marrone, and defensive coordinators George Edwards, Dave Wannstedt, Mike Pettine, and Jim Schwartz in his four seasons with the Bills.
