Arizonans are accustomed to seeing old bands that have reunited. Chances are there is one playing this weekend at a neighborhood casino.

There also will be a reunion, of sorts, at University of Phoenix Stadium on Sunday. Four members of the Cardinals’ 2004 draft class, the best in the team’s history in Arizona, will be playing.

Two of them, receiver Larry Fitzgerald (first round) and defensive end Darnell Dockett (third) have never played for another team.

One, inside linebacker Karlos Dansby (second), is back with the Cardinals after spending three seasons with Dolphins. The fourth player, end Antonio Smith (fifth), is in his fifth season with the Texans after signing as a free agent in 2009.

Dockett credits Dennis Green, who was in his first year as Cardinals coach in 2004.

“We always talk about that,” Dockett said. “Even to this day, we’re thankful to him to come get us and giving us the opportunity to play early. A lot of teams would get young guys and they’d have to sit on the bench for two, three years. But he put us right in and let us play.”

Green didn’t have much choice since he inherited a team depleted of talent and emerging from salary-cap purgatory. And while Fitzgerald and Dockett made an immediate impact, it took Dansby and Smith a couple of years to fulfill potential.

That class bolstered Green’s reputation as an astute judge of talent, but Green didn’t come close to duplicating it in the next two years. Only one player from the 2005 draft, safety Antrel Rolle, made a significant contribution. The 2006 draft, headlined by Matt Leinart, didn’t produce much, either.

Few draft classes compare with the Cardinals’ in 2004. Together, Fitzgerald, Dansby, Dockett and Smith have played in 590 games, starting 554, and been selected to 11 Pro Bowls, led by Fitzgerald at seven.
