The New York Giants have some depth this season at running back. They have three options at the running back position and they all have a chance to get some playing time. Rashad Jennings should get the most carries at running back. Shane Vereen should get the most passing action.
Of course the Giants also have second year player Andre Williams. Williams was pretty effective as a starter when Jennings went down with an injury. Williams was actually more effective as a starter than as the Giants back up running back.
When it comes to Fantasy Football it can be extremely difficult to feel comfortable starting running backs when they do not have a defined role.
