The roots of the Tampa 2 system actually come from the Pittsburgh Steelers and their Steel Curtain defense of the 1970s. "My philosophy is really out of the 1975 Pittsburgh Steelers playbook," said Dungy (who played for the Steelers early in his career) during media interviews while at Super Bowl XLI. "That is why I have to laugh when I hear 'Tampa 2'. Chuck Noll and Bud Carson—that is where it came from, I changed very little." Lovie Smith mentions having played the system in junior high school during the 1970s, though Carson introduced the idea of moving the middle linebacker into coverage. Carson's system became especially effective with the Steelers' addition of aggressive and athletic middle linebacker Jack Lambert.
