He's got incredible speed. He gets to the basket with incredible ease a lot of the times, and he has a great shooting touch.
I disagree with this. Last night he got to the basket, but that is because the Knick's were not even trying to keep him in front of them, and they had no help defense. Even Sasha and Troy Murphy were getting to the hoop. However, he has not showed any kind of first step against normal defenses.
That is one of the biggest things he needs to work on. His handle is just not strong enough, and his footwork needs a lot of work before he is able to take advantage of that speed to consistently beat guys off the dribble.
As for the shooting touch, he does seem to have a decent one, but again, he needs to get more consistent. Right now he is VERY streaky, and when he is not locked in, he is liable to miss by 4 feet. While some of that is confidence, a lot of it is his footwork. Particularly when he is facing real pressure, his feet are all over the place, and he doesn't get good balance when shooting. Last night he looked better because the Knicks never closed out on him, so he could shoot as if it were practice.
Basically, he is just a work in progress. Unlike a guy like Giddens, he is still very young, and seems willing to learn. But until he can work out some of those real, fundamental problems, he is not going to be anything more than a D-leaguer.
