About Buddy Ryan
James David "Buddy" Ryan (February 17, 1931 – June 28, 2016) was an American football coach in the National Football League (NFL) and American Football League (AFL). During his 35-season coaching career, Ryan served as the head coach of the Philadelphia Eagles from 1986 to 1990, and of the Arizona Cardinals from 1994 to 1995. Ryan also served as the defensive coordinator of the Chicago Bears from 1978 to 1985, and of the Houston Oilers in 1993. Coaching multiple Hall of Fame defensive players throughout his career, Ryan is considered by many to be one of the greatest defensive minds in the history of American football. Ryan began his professional coaching career as the defensive line coach for the New York Jets of the AFL for the team's Super Bowl III victory. He became the defensive line coach for the Minnesota Vikings, overseeing the Purple People Eaters. He then became the defensive coordinator of the Chicago Bears, who won Super Bowl XX. As defensive coordinator of the Bears, he is credited with creating the 46 defense, and the 1985 team led the league in nearly all defensive statistical categories. Ryan then coached the Eagles, served as defensive coordinator of the Oilers, and coached the Cardinals. He was the father of NFL coaches Rex Ryan and Rob Ryan. He and Walt Michaels' defensive game plan was instrumental in holding the NFL's Baltimore Colts to seven points in Super Bowl III and earning Ryan his first Super Bowl ring. The 1976 Vikings won the NFC Championship and appeared in Super Bowl XI. When Wooten became head coach at Marshall High School in 1959, Ryan was promoted to head coach at Gainesville where he was also the athletic director.
