I really like him, but at the moment all I can see is a backup. He really needs to add weight and keep it on. Maybe now that he's a pro he can hire someone to do this, or work with the team. His biggest issues are in pass-pro, which is an issue for this offense...but most of it comes back to his inability to anchor down in pass-pro because of his lack of weight.
When you watch him he almost gets straight up and down and is nearly "hopping" on his feet as defenders drive him back. He needs to be able to anchor down and sit down in his spot and hold - and without any weight (or unusual strength) he's going to struggle.
I like him - and I think he is a good backup option, and can move in space and in the run game...but he's got a lot of work to do in the passing game.
