up for games were most often rooting for the away team, creating "home games" on the road for many opposing teams—a phenomenon most noticeable when teams with great national followings, such as the Packers, Bears, 49ers, Raiders, Redskins, Steelers and Cowboys, came into town. 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 2002, the addition of the Houston Texans caused the NFL to realign into eight divisions of four teams each. After 32 years of being in the NFC East, the Cardinals were finally moved to the NFC West with the 49ers, Seahawks, and Rams, which made far more sense from a geographical standpoint. Green era (2004–2006) In 2004, the Cardinals hired former Vikings coach Dennis Green as their head coach. Prior to his signing with the Cardinals, he compiled a 97–62 record in ten seasons with Minnesota (1992–2001), leading that franchise to four NFC Central Division titles and two NFC Championship games. The Cardinals continued their mediocre ways, going 6–10 in 2004 and 5–11 in 2005, the final two seasons for the team in Sun Devil Stadium. Tragedy struck the team on April 22, 2004, when former safety Pat Tillman, a popular player who was an All-American at Arizona State, was killed in Afghanistan while serving in the United States Army. Tillman left professional football following the 2001 season to serve in the military in the wake of the September 11 terrorist attacks. Tillman became the first NFL player to lose his life in war since Buffalo Bills offensive tackle Bob Kalsu died in 1970 during the Vietnam War. Tillman's jersey number 40 was retired at the Cardinals' first home game of 2004. In early 2005, Cardinals signed Kurt Warner to a one-year, $4 million contract and later extending it to six years. Warner retired on January 29, 2010. Matt Leinart was drafted tenth overall in the 2006 NFL draft. After four seasons, Leinart was released on September 4, 2010, and signed a one-year contract with the Houston Texans two days later. New stadium (2006) In 2000, Maricopa County voters passed a ballot initiative by a margin of 51% to 49%, providing funding for a new Cardinals stadium (as well as for improvements to Major League
