a late-bloomer.
He's not the monster yet that he's pretty surely gonna become. He shouldn't roll his dice with the NFL draft till the monster has begun to manifest itself a little more, I think. There's not a single college QB who was so talented as to presume that their early NFL career wasn't gonna require their utmost personal best effort (& more than a bit of good fortune) to ultimately translate into a long term starting role for a franchise. You don't go into something like that if you aren't yet fully grown, imo. Not if you really want to give yourself your best shot at succeeding.
