I'm cautiously optimistic on him right now. He's on a team that's under the radar, has a fragile RB working directly in front of him and an offense that's starting to shape up nicely. He feels kind of like a mix of Chris Johnson and Maurice Jones-Drew, although I believe he needs to work on his receiving skills.
He could also be the next Darren Sproles, where he's got value but will never be seen as a true #1 if Caddy goes down. However the release of Ward seems to make me think the coaching staff believes in him enough to at least try it.
