The nickel defense originated as an innovation of Philadelphia Eagles defensive coach Jerry Williams in 1960 and used successfully in the Eagles' Championship victory over Vince Lombardi's Green Bay Packers that year. He later employed it effectively as a measure to defend against star tight end Mike Ditka of the Chicago Bears, holding Ditka to a single reception in the Eagles' 1961 victory over the Bears. The nickel defense was later used by then Chicago Bears assistant George Allen, who came up with the name "nickel" and later marketed the idea as his own. The nickel defense was popularized by head coach Don Shula and defensive coordinator Bill Arnsparger of the Miami Dolphins in the 1970s and is now commonly employed in obvious passing situations or against a team that frequently uses three+ wide receiver sets on offense.
