I think Parker might be a very dangerous NBA prospect. He's a 6'8" wing/PF. A tweener. Lacks the explosiveness that wings must have yet lacks the size for a PF. Is he D-Will 2.0? Is he Thomas (who went to Kansas and who cannot seem to get any PT in the association)? Or Beasley? Is he that Ohio St tweener drafted by the celtics whose name is escaping me? Is he Jeff Green? None have set the world on fire. Or (best case) is he Melo? Who... Again, hasn't set the world on fire.
Honest question. Have you ever seen Jabari Parker play? He's a true small forward. He lacks explosiveness? That's news to me. I honestly laugh at people like you because you're literally a boxscore scout. Please actually watch a player before you start making judgements? Parker is a very good athlete and is very good at handling the ball. See below.
