Just thought about it, what a beautiful weapon to have.
After reading into him a bunch I'm beginning to feel for me personally he's the gem of the draft. It used to be Garoppolo but I've changed my mind. He's much alike with Tavon Austin I feel even though quite honestly I think he may be a knotch under him simply(I think it's unfair to say so so early). By all means however they're very much alike. To me Tavon will become an incredible player much in the ilk of Steve Smith.
(Here's gang green's profile on him http://www.ganggreennation.com/2014/1/17/5319944/scouting-the-draft-dri-archer-rb-kent-state)
He's a cheaper and more easy to obtain Tavon. I wouldn't use him as RB but I would think that using him at WR to run the wrap around play we do with Alshon would be super impactful.
