A founding member of the NFL.
One of three remaining original teams in the NFL. (Green Bay Packers and Chicago Bears are the other two)
Between 1960 and 1987 they played in St. Louis. Causing some confusion, as the Major League Baseball team of the same name played in the same city.
They have not won a championship in the Modern era, their last championship was in 1947 (they also won in 1925). They were the NFC Champions following the 2008 season.
