A league source tells us that the Patriots have agreed to terms with safety John Lynch.

Lynch, a nine-time Pro Bowler, could assume the role that the team was exploring for Tank Williams, who recently landed on injured reserve with a knee injury.  Williams had been practicing at linebacker.

At this stage of his career, Lynch probably is a better fit playing closer to the line of scrimmage.  Besides, the team already has a Lynch-style safety in Rodney Harrison.

UPDATE:  Coach Bill Belichick opened his press conference by saying that Lynch is not yet under contract.  We still stand by our source.  Unless our source was wrong.  (Hey, it worked for Mort last year.)
