Eagles running back Darren Sproles is spending a lot of time at wide receiver in training camp. Head coach Chip Kelly is confident that Sproles understands his role as a back and wants him to be even more versatile than he already is. "It's year two for him, so I think he feels really comfortable in terms of what our running backs are doing," Kelly said. "So we are just kind of cross-training him like we do some other guys in terms of how do we get our best players on the field and put them in different situations.
