When did the Cardinals move to AZ? Last I heard they were still in St. Louis!
The team was established in Chicago in 1898 and was a charter member of the NFL in 1920. Along with the Chicago Bears, the club is one of two franchises still in operation since the league's founding. The club moved to St. Louis, Missouri, in 1960 and played in that city through 1987 (sometimes referred to as the "football Cardinals", "Big Red" or "Cardiac Cards" to avoid confusion with the baseball St. Louis Cardinals). Before the 1988 NFL season, the team moved to Tempe, Arizona, an eastern suburb of Phoenix, and played their home games for the next 18 years at Arizona State University's Sun Devil Stadium. In 2006 the club began playing all home games at the newly constructed University of Phoenix Stadium in the northwestern suburb of Glendale.
