As everyone says, he has talent, so they're betting that he has upside. But I don't see it. I don't think he has the bball IQ to be anything more than a microwave scorer / defensive liability off the bench. Some scout labeled him something to the effect of "Worse awareness on both sides of the ball than Nick Young."
He could be a lateral move from Nunn, which is no good cause you gave up 3 picks AND are talking about tying some of your money up with him.
And his length is irrelevant if he has no clue what he's doing on defense.
@FAH1223, tell 'em what you think of Rui.
