The Doomsday Defense was the defense of the Dallas Cowboys American football team during the dynasty years of the late 1960s – 1970s. This defense was the backbone of the Cowboys’ dynasty, which won two Super Bowls (VI, XII) and played in three more (V, X, and XIII). The Doomsday Defense is often recognized as having two different “generations,” but different listings of players and time periods exist. The original “Doomsday Defense” can generally be identified as the Cowboys’ defenses from 1966 to 1974.
