Whenever the Cardinals struggled, Sun Devil Stadium was frequently one of the quietest stadiums in the league. Cardinals home games often did not sell out in time for them to be aired locally, in compliance with NFL blackout policy at the time. The few fans who did show up for games were most often rooting for the visiting team, creating what amounted to "home games" on the road for many opposing teams, a situation most prevalent with the fans of the Dallas Cowboys, who were in the same division with the Cardinals (the NFC East, an artifact of their former St. Louis home) until the Cardinals moved to the NFC West in the 2002 season and often "de facto" had a home-field advantage for their yearly road game in Tempe. A significant percentage of the state's residents only live there during the winter and live elsewhere for the rest of the year, and many of Arizona's permanent residents either grew up in other states or have roots outside the state. In 2005, for instance, all home games (except for the 49ers game which was held at Estadio Azteca in Mexico City) failed to sell out and could not be broadcast on local television.
