To be fair he is pretty much right, if he had normal PG size it would help one of his weaknesses(being able to see the floor better), he would be a nightmare with his quickness(even more than he already is because he would be a more explosive finisher around the basket), shooting ability(he would actually be a better shooter if he was taller, being able to elevate and shoot over defenders more comfortably, he's already a very good shooter as is), but he isn't so that is why his market value is expected to be the same or similar to guys like Jodie Meeks, Grievis Vasquez, Carl Landry, Jason Thomspon etc.
If I was taller and male, I might have been a fighter pilot...
He is who he is. He really needs to find a way to be comfortable with the things he cannot change.
