"Also this afternoon, former Redskins starting safety Ryan Clark agreed to a four-year contract with Pittsburgh, according to his agent, Joel Turner. Clark, who went from obscurity to become a regular contributor on one of the NFL's premier defenses, spoke with Washington for the better part of a year about a contract extension, but a deal could never be reached.
Clark's first visit was with Pittsburgh yesterday -- he was the first free agent entertained by the Super Bowl champion Steelers as well -- and final details of the contract were settled around 2:30 this afternoon. Clark came to Washington in 2004 after being cut by the New York Giants and was not expected to make the team but ended up getting a starting spot.".
