The Miami Dolphins won Super Bowls VII and VIII. The Pittsburgh Steelers immediately followed as back-to back-winners when they won Super Bowls IX and X. Pittsburgh accomplished the feat again in Super Bowls XIII and XIV. The San Francisco 49ers won Super Bowls XXIII and XXIV. The Dallas Cowboys won Super Bowls XXVII and XXVIII.
