The Arizona Cardinals are a professional American football team based in the Phoenix metropolitan area. The Cardinals compete in the National Football League as a member club of the National Football Conference West division. The Cardinals are the oldest team in the National Football League (NFL), but they are also one of the least successful franchises in league history, having won just two NFL championships (1925 and 1947) since the team’s founding in 1898.In 2013 the Cardinals won 10 games for the second time since the franchise relocated to Arizona, but the team did not qualify for the postseason. The team won 11 games in 2014 to earn a play-off spot, but the injury-plagued Cardinals—who were starting a third-string quarterback by the postseason—lost their opening play-off contest. The following season saw Arizona win 13 games (the highest total in the team’s 96 years of existence up to that point) and a division title. The Cardinals won their opening play-off contest over the Green Bay Packers in dramatic fashion by rallying from a last-second hail-mary touchdown that had tied the game to win the game just three plays into overtime.
