The sad day in the world of sports continues as we learn of the passing of former football coach Buddy Ryan at the age of 82.

Ryan was the head coach of the Philadelphia Eagles and Arizona Cardinals while also serving as the defensive coordinator of the Chicago bears and the Houston Oilers. Ryan went 55-55 in his head coaching career, but was unable to win in the playoffs.

Ryan is most famous for being the architect of the '46 Defense' that culminated to a Chicago Bears Super Bowl XX win over the New England Patriots 46-10. Ryan was carried off the field by some of his defensive players after the game, including Mike Singletary and Ron Rivera, the current head coach of the Carolina Panthers.

Ryan was the head coach for the Eagles from 1986-1991 as he went 43-38-1. In 1994 he became the head coach of the Arizona Cardinals.

Ryan's sons, Rex and Rob, are now the head coach and defensive coordinator of the Buffalo Bills respectively.
