One thing I've noticed is that he seems to be a little over taken with his touch, which is very good. He has great touch and anticipates throwing to different levels well, but he struggles at times, when he needs to rip it, instead throwing a touchy pass.
Could be footwork could be a mental thing, dunno yet. Does seem when his footwork is right, he has a plus arm. Its not Stafford, but really, who is? Dude could throw a tennis ball thru a brick wall.
