Eight teams have won back-to-back Super Bowl titles, but no team has pulled off the feat in 19 years, since Tom Brady and the New England Patriots defeated the Carolina Panthers 32-29 in Super Bowl XXXVIII following the 2003 season, then knocked off the Philadelphia Eagles 24-21 in Super Bowl XXXIX a year later.
A handful of teams have had a chance at consecutive titles in the ensuing years but couldn't pull it off.
Last year, Kansas City beat Philadelphia 38-35 in Super Bowl XLII, setting the Chiefs up for another chance to become back-to-back champs — but first they'll have to pull off another win over the 49ers in Super Bowl LVIII.
The other teams to have won Super Bowl titles in consecutive years are the Green Packers (Super Bowls I and II), Miami Dolphins (Super Bowls VII and VIII), Pittsburgh Steelers (Super Bowls IX and X, and Super Bowls XIII and XIV), the 49ers (Super Bowls XXIII and XXIV), Dallas Cowboys (Super Bowls XXVII and XXVIII) and the Broncos (Super Bowls XXXII and XXXIII).
