A good one at several positions if the Giants lose Mannigham, Ross, and McKenzie, also if Ballard and Beckum are not ready for the season start.

WR Vincent Jackson would make a great target for Eli in this offense, Visanthe Shiancoe would be a good addition, and Carlos Rogers, coming off a great year for the Niners is available along with S Dashon Goldson.
The Giants may take a hit losing free agents this coming year, they can't pay everyone, but they may be able to sign some very good free agents who are looking for a playoff/Super Bowl type of team.
