The 2009 season was the team's most successful season, which culminated in the franchise's first league championship win against the Indianapolis Colts in Super Bowl XLIV. After achieving a record of 13–0 with their win over the Atlanta Falcons, it marked the Saints' best start to a season in its franchise history. The result clinched an NFC playoff berth, a bye in the first round of the playoffs. By winning their first 13 games, the Saints also set the record for the longest undefeated season opening (13–0) by an NFC team since the AFL–NFL merger, surpassing the previous record (12–0) held by the 1985 Chicago Bears. However, they would fall victim to the Dallas Cowboys in week 14, going on to end the season with a three-game losing streak. The Saints became the first team to win a Super Bowl after losing its last three regular season games.
