 The Bears' iconic 46 defense (Named after former Bears' safety, Doug Plank), led by mercurial Defensive Coordinator Buddy Ryan, was an "attack from all angles" scheme that resulted in, arguably, one of the greatest overall team defenses in league history.With future Hall of Famer Mike Singletary (#50) flanked by the supremely athletic Wilber Marshall (#58) and Otis Wilson (#55), the linebacking unit ranked in at #5 of the greatest linebacking corps in NFL history in NFL Top 10.Coupled with a solid backfield anchored by safeties Gary Fencik (FS) and Dave Duerson (22), and a defensive line that included future Hall of Famers Richard Dent (#95) and Dan "Danimal" Hampton (#99), along with the gritty Steve McMichael (#76) and breakout media superstar rookie, William "The Refrigerator" Perry (#72), the Bears were famous (or infamous) for getting to the quarterback early and often and completely disrupting their opponent's offensive game plans.
