Super Bowl LI was the first Super Bowl to go into overtime with a 28-all tie between the Atlanta Falcons and New England Patriots, which the Patriots eventually won with James White scoring a touchdown on the Patriots' first drive.
History of the Green Bay Packers
By winning the 1967 NFL Championship Game, the Packers achieved a "three-peat" (three consecutive league championships) for only the second time in franchise history and the first time since they were named league champions following the 1929–31 seasons. To this day, no other NFL team has matched or surpassed this record. The Packers' back-to-back wins in the first two Super Bowls remains a Super Bowl record, and has since been tied seven times by six other franchises: the Miami Dolphins won Super Bowls VII and VIII following the 1972 and 1973 seasons, the Pittsburgh Steelers won Super Bowls IX and X following the 1974 and 1975 seasons as well as Super Bowls XIII and XIV following the 1978 and 1979 seasons and remain, to date, the only team to win back-to-back Super Bowl titles more than once, the San Francisco 49ers won Super Bowls XXIII and XXIV following the 1988 and 1989 seasons, the Dallas Cowboys won Super Bowls XXVII and XXVIII following the 1992 and 1993 seasons, the Denver Broncos won Super Bowls XXXII and XXXIII following the 1997 and 1998 seasons, and most recently, the New England Patriots won Super Bowls XXXVIII and XXXIX following the 2003 and 2004 seasons.
