The Giants have signed 29-year old QB Jim Sorgi to a 1-year deal to replace David Carr as Eli Manning’s backup.  Sorgi did not play last season due to a shoulder problem but he has been cleared to return to action for 2010.  Sorgi has played in 14 games in his NFL career and he has completed 99 of 156 passes (63.5%) for 929 yards with 6 TD passes and 1 INT (89.9 QB Rating).  He also has carried the ball 31 times for 0 yards (0.0 ypc) in his NFL career.  Sorgi doesn’t have David Carr’s arm strength but he is a solid backup QB.
