The franchise's lone NFL championship game victory came in 1947 while they were based in Chicago, and came two decades before the first Super Bowl game was ever played. The club's other NFL championship occurred in 1925, eight years before the league began holding a championship game, and is a controversial title to this day. The much contested title was believed to belong to the Pottsville Maroons but was given to the Cardinals instead in what is called the 1925 NFL Championship controversy. In the six-plus decades since winning the championship in 1947, the team has qualified for the playoffs only six times and has won only five playoff games, three of which were achieved during their ongoing run in the 2008-09 NFL Playoffs.
