They've made the playoffs 10 times and won seven of them, three of which came during their run in the 2008-09 NFL playoffs. They won their lone NFC Championship Game since the 1970 AFL-NFL merger and advanced to Super Bowl XLIII that season (losing 27-23 to the Pittsburgh Steelers). The Cardinals have been to six NFL Championships in their history. They've won three of them - 1947, 1948, and 2009. The other three were lost: 1920 (claimed by default due to the Federal League refusing to play postseason games), 1986 (lost to the Miami Dolphins), and 2012 (lost to the San Francisco 49ers). In World War II, the Cardinals played a series of eight games against top military teams. The Cardinals won five of those games (including two after the war had ended) to earn the title of world's best football team. During their playoff runs in 2008 and '09, head coach Ken Whisenhunt called his team the greatest he'd ever coached against. Both seasons ended in disappointment (with neither making it past the divisional round), but still, they're considered among the best campaigns in franchise history. The Cardinals have only missed the playoffs four times since 1949.
