The 1947 Chicago Cardinals season was the franchise's 28th season in the National Football League. The Cardinals won the second NFL championship in team history against the Philadelphia Eagles. The team was led by its "Million Dollar Backfield" of Elmer Angsman, Charley Trippi, Paul Christman, and Pat Harder. The Cardinals, however, wouldn't win another playoff game for an NFL record 51 years. As of the end of 2021, this is the team's last league championship. This championship drought is currently the longest active one in American professional sports. Until the 2018 season 71 years later, this and 1949 also marked the last time the Cardinals beat the Green Bay Packers on the road.
