Super Bowl XLII featured the National Football Conference (NFC) champion New York Giants and the American Football Conference (AFC) champion New England Patriots in an American football game to decide the National Football League (NFL) champion for the 2007 season. In one of the most significant upsets in Super Bowl history, the Giants (14-6) won 17-14, preventing the Patriots (18-1) from becoming the first undefeated team since the 1972 Miami Dolphins went 17-0. Instead, the Giants became the first NFC wild card team to win a Super Bowl, the fifth wild card team to win overall, and the fourth in eleven years. The win was also their first title in 17 years and their third overall.
