While Larry Fitzgerald remains quite capable of making a big play every time the ball is thrown his way, we're told it might take a little while before the Cardinals' star wideout has his act 100 percent together again, both physically and mentally. Fitzgerald clearly did not have his usual big-play burst in Arizona's season opener and still looked like he was feeling the effects of the sprained knee ligament he suffered in the first preseason game. In addition, he openly acknowledges the need to develop a much better chemistry with starting QB Derek Anderson after missing valuable practice time when he was sidelined with the injury from mid-August through the first week in September. "Fitzgerald and (Kurt) Warner both knew exactly where the ball was going all the time," one insider said. "He and Anderson just don't know each other nearly as well, and Anderson's throwing issues don't help."
