Some things I noticed in this video and other videos of his I've watched:
-Excellent vision, sees things happening that are not directly in his line of vision.
-Doesn't often lose yardage.
-Very efficient in movement, doesn't make a lot of unnecessary cuts that hurt momentum.
-Patience, willing to let the blocking develop and see what the play is giving him.
-Needs space to operate, has trouble when the defense is on top of him.
Soooo... Darren Sproles 2.0?
