What about Mike Gandy?
Kerry Rhodes?
Richard Marshall?
We do ok in free agency, but I know what you mean. AZ really should stick to adding bit parts in FA because we have a history of "swinging and missing" when it comes to the big fish.
Mike Gandy was improved because of the quarterback playing behind him. Warner's presence likely added $5 million or more to Gandy's bank account.
Kerry Rhodes was a Pro Bowler in New York.
Richard Marshall was believed to be a rising star before the 2010 season when Peppers was gone and he became toast without much of a rush in front of him.
Jeff King was a great surprise. I think that Paris Lenon has been far more than we expected of him. Bertrand Berry was better for a year here before his injuries caught up to him. I'd argue that Chike Okeafor was better here than he was in Seattle before he suffered the pec tear.
