The genesis of the defensive system that Carolina football and coordinator John Papuchis use today dates to the mid-1990s and a frustrated coach trying to prepare his Cleveland Browns to face the Pittsburgh Steelers. The Steelers at the time had the ability to play smash-mouth inside the tackles and pound you to a pulp, but they also had some good receivers and were playing at times with four-wides—one of the early NFL teams to flirt with a spread attack. The Browns favored a Cover-3 base (three deep defensive backs playing thirds of the field), which was soft if the Steelers sent four receivers deep on "go" routes.
