Cards say they won't trade Dockett
Dockett told the Cardinals after the Super Bowl that he felt he had outperformed the five-year, $22.010 million contract he signed in 2006, the source said.
The team told him then they would not trade him but might consider discussing his contract. No talks on a new deal have occurred this offseason, so Dockett restated his trade request.
Top defensive tackles are making $8 million a year or more, and Dockett, according to the source, would like to be traded in order to receive a top defensive line contract.
His agent, Drew Rosenhaus, declined comment.
Coming off a loss to the Steelers in Super Bowl XLIII, Cardinals coach Ken Whisenhunt looks ahead to the 2009 season.
Boldin and Dockett both cited hamstring injuries in missing post-draft practices. Rosenhaus represents both players.
