Kevin Durant, really? He is nowhere near as skilled, and certainly not as good a shooter as Durant. In the videos I have seen he has looked like he doesn't have much of a first step, and his handle is VERY loose (he makes Jeff Green look like Rondo). He has a long way to go.
You really think his handle is loose? Are you just going off of highlights? There are full games of his available and his handle looks really good. He actually brings the ball up a lot, which doesn't mean anything if he's not pressured but he looks really comfortable dribbling in all scenarios, including going full speed and changing directions. He doesn't fight the ball and is equally dexterous with his right and left hand.
The guy is such a gamble because he hasn't been exposed to a high level of competition but at least he's not a rail-thin 22 year old playing against subpar competition and just getting discovered. For a 18 year old, he's got a very good feel for the game, a pretty high skill level and promising physical gifts. From what I can tell, he looks like he's been coached well and has a knack for the game. He is what he is, a skilled 18 year old prospect who could be a bust or could turn out to be a solid player or maybe more, maybe much more.
