Its quite possible. Just very, very rare for someone who is a competitive athlete. Hes got to have a pretty lean frame, would be suprised if his bone structure isn't also pretty narrow. If thats his current size I wouldnt use a first rounder on him, he may naturally gain weight/strength, but its not a garuntee. And I would be SHOCKED if he has enough strength for the pro game if thats his current weight. Regardless of his current weight, if that was ever accurate I would also looking into things like Marfan's syndrome in his case, as that could potentionally cut his career short. As a tall (not quite that) skinny guy when I was that age I wouldnt right him off, but I would be very cautious approaching him if I were a team. Do a thorough physical, collect as much family history info as possible, that sort of thing.
