Buddy Ryan was one of the best defensive coaches in the NFL of all time, known for creating some of footballs best defenses. He is well known as the architect of the 46 defense which helped the Bears win their Super Bowl in 1986. Buddy Ryan was a defensive genius in the history of NFL.
The scene was remarkable not just because it was poignant but also because it was so unusual. The 1985 Chicago Bears had just finished off a 46–10 deconstruction of the overmatched New England Patriots to win Super Bowl XX in the Louisiana Superdome, and the giddy celebrations had begun on the field. Chicago coach Mike Ditka, beloved by these Bears, was lifted onto the shoulders of some of his players—this came as no surprise. But then the strangest thing happened: Suddenly there was Bears defensive coordinator Buddy Ryan being hoisted by linebacker Otis Wilson and defensive end Richard Dent, Ryan’s right leg over Wilson’s left shoulder pad and his left leg on Dent’s right pad, both men laughing, while the rumpled old coach, stuffed into his Bears sweater, awkwardly tried to keep his balance. A defensive coordinator getting a victory ride?
It shouldn't even be debated whether Buddy Ryan was one of the best defensive coaches of all time. His defenses dominated every statistic on the defensive side of the ball. The defense is the sole reason for his teams making three super bowls. Everyone remembers the Chicago Bears defense of 1985.
I do not think that defensive coach Buddy Ryan was the greatest of all time in the NFL. There are many defensive coaches that work in the NFL, both past and present, that have very different coaching styles. It is nearly impossible to compare them to each other. Therefore, it would be hard to chose who was the best.
