The NFL introduced wild card entries into the NFL Playoffs in 1970. In 2020, three wild card teams will make the playoffs from each conference for the first time, up from two. That obviously increases the chances one such team will win the Super Bowl. Since 1970, 10 wild cards have advanced to the Super Bowl and six went on to win it, including the:
Oakland Raiders (1980)
Denver Broncos (1997)
Baltimore Ravens (2000)
Pittsburgh Steelers (2005)
New York Giants (2007)
Green Bay Packers (2010)
