Giants beat writer Dan Graziano gives his take on the Giants backfield:
The Giants signed Rashad Jennings to be their starting running back. They believe he's ready at this stage of his career, after backing up guys like Maurice Jones-Drew in Jacksonville and Darren McFadden in Oakland, to handle a starter's workload. They believe he can catch the ball for them out of the backfield, that he can grind out yards between the tackles and that he's capable of delivering a big play. Assuming he picks up the blocking schemes and can help in pass protection, he's their guy.
That said, Wilson is still on the team, and if the 2012 first-round draft pick shows he's recovered from neck surgery, there is surely going to be a role for a player with his skills. The Giants are hearing good things about Wilson's recovery, but they know they can't count on him, so they signed Jennings and brought back Peyton Hillis in order to construct a backfield in case Wilson can't be a part of it.
I think their plan is for Jennings to get the bulk of the carries with Hillis as his backup, and if they are pleasantly surprised by Wilson's health and availability, they will find ways to work him into the offense. If healthy, he offers a lot.
Jennings was the #6 RB from Week 9 to Week 15 (when he was playing starter’s snaps for the Raiders) and that included a missed game against the Jets in Week 14. The team still believes in David Wilson, but Jennings is fully capable of winning the RB1 job outright. The Giants had a very difficult time running the ball in 2013, so they need to sort out the offensive line as well. Still, Jennings is a three-down back and has a relatively clear path to a starting gig. For a closer look at Jennings' potential workload and production, click here.
