The Saints have signed 33-year old free safety Darren Sharper.  Sharper played in all 16 games for the Vikings last season and he made 69 tackles, defensed 5 passes and intercepted a pass.  He has now played in 183 games in his NFL career and he has made 856 tackles, defensed 118 passes, has 7 sacks, has forced 9 fumbles and he has intercepted 54 passes (8 of which he has returned for TDs).  This was a outstanding move for the Saints who need a playmaker at the back end of the defense.
