The Giants have signed 31-year old strong safety Deon Grant to a 1-year deal.  Grant played in all 16 games for the Seahawks last season and he finished up with 78 tackles, 2 tackles for a loss, 1 forced fumble, he defensed 8 passes and he had 3 interceptions.  Grant has now played in 144 games in his NFL career and he has made 640 tackles, defensed 92 passes, he had 4.5 sacks, forced 2 fumbles and he had 26 interceptions.  This was a excellent move for the Giants as Grant will team with Antrel Rolle to give them a very nice set of safeties for 2010.
