7. Jacquian Williams
A teammate of Jason Pierre-Paul's at both Fort Scott Community College and the University of South Florida, Williams made what is perhaps one of the Giants' most pivotal plays of the last decade when he stripped 49ers punt returner Kyle Williams in overtime of the NFC Championship game. His forced fumble led to a Devin Thomas recovery and, a few plays later, a Lawrence Tynes field goal that catapulted the Giants to their Super Bowl title.
Williams had a decent 2012 season at linebacker, but his presence has mostly been felt on special teams. His quickness and agility bodes well for him at a particularly weak position for the Giants: a position where they are desperate for some kind of spark.
