What do you do with him as a pro to get him on the field? Make him a running back? A receiver? See if he can be a kick/punt returner? Wildcat guy like Brad Smith? His athletic ability translates to the next level with ease but as what? What part of the draft would you risk taking a college QB with his athletic skills that will need a position change?
Not enough info yet, teams will have to see his pro day and workouts before they guess what can be done with him. But one thing that needs to be abandoned is "Wildcat QBs." When you send a guy out there that everyone knows only runs the football so that he can run "trick" plays that fool no one it just stalls the offense and hurts the rhythm of your real quarterback. The Wildcat is only going to succeed consistently in college and high school where team have overwhelming athletic advantages and all they need to do to move the football is give a good athlete a little blocking. NFL defenders are generally too good for this kind of play to work. Wildcat had a brief boom a few years ago after Miami used it to surprise the Patriots for a win. But with the novelty gone there's no surprise to it so it's not going to work. So either decide that Robinson can be taught quarterbacking at the NFL level and put in the time to make him one or turn him into an RB, WR, or just kick returner. But don't waste everyone's time with the Wildcrap offense.
Coming out of high school, Michigan initially recruited him as a defensive back. Scout.com even ranked him the 16th best CB in the nation. Be a cool story if he made that switch. With his speed and height (6'1") it may be worth the try if you take him in a later round.
