2006 Arizona Cardinals season

The 2006 season was the Arizona Cardinals' 87th in the National Football League (NFL) and their 19th in Arizona. The season began with the team trying to improve on their 5–11 record in 2005. They also moved into the Cardinals Stadium in Glendale, Arizona (one of the western suburbs of Phoenix), the first-ever stadium in the United States with a retractable playing surface. The stadium was christened University of Phoenix Stadium on September 26, and managed to sell out every home game. Despite a somewhat promising start, the team suffered a few setbacks, including key losses to the Dallas Cowboys and most memorably the eventual NFC Champion Chicago Bears, and ended the season (again) at a disappointing 5–11 record. Head coach Dennis Green was fired after the season, replaced by Ken Whisenhunt.
