Deep range does not mean from 3, he states 3 point or NBA 3 point range for that. It refers to his ability to shot from outside the paint and knock down jump shots, which he can and does.
Also, have you watched him this year? How many people on this board have? I have, a number of times, he is a much better and more aggressive player then he was 2 years go at UConn.
EDIT: To note, I do not think he will be a first round pick this year and I doubt next year unless there is an improvement in his game, but I do think he can play in the league because of his ability to rebound, defend, stretch the floor and score from 16 feet.
