The Steelers have re-signed 30-year old safety Ryan Clark to a 4-year, $17 million dollar deal.  Clark played in 15 games for the Steelers last season and he made 89 tackles, defensed 8 passes and he had 3 interceptions.  He has played in 48 games in his four years with the Steelers in which he has made 270 tackles, defensed 20 passes, has 1 sack, forced 1 fumble and he has 5 interceptions.  This was a smart move for the Steelers as Clark has really been a solid player for them the last few years.
