With a league-most six Super Bowl titles, the Steelers have plenty of great teams to choose from. The 1975 team gets our nod by the slimmest of margins. The Steelers had the highest point differential (plus-211) in the league, thanks largely to a dominant defense. Cornerback Mel Blount won the Defensive Player of the Year Award, and the team defeated the Cowboys, 21-17, in Super Bowl X, in a game highlighted by an MVP performance from Hall of Fame receiver Lynn Swann.
