I thought he progressed really nicely for a rookie. I really didn't expect anything from him at WR, so I was very impressed by his hands, and even a bit by his route running. He still needs to bulk up and work on being more elusive in tight space, but he is off to a decent start there considering how spotty the QB play was. He just missed having at least 3 more receiving TD's, be it because of overthrows or whatever.
I was not impressed early on with his returns at all. He looked beyond tentative, and even though he did have a kickoff return for 6 against Philly, and another two called back on stupid penalties, I just didn't see any consistency. I don't expect him to bust one every time he touches the ball, but so many times he would almost just go down on his own when a defender came within reach. This is where hopefully he can also become a bit more shifty instead of being just a straight line burner.
The potential is definitely there with the guy, but so far, I would say he surpassed my expectations at WR, but fell a little short of them in the return game.
