Go watch some of his high school tape and you should see the difference in athletic ability. Granted I am not sure how tough the competition was, but he was pretty smooth. He made quick decisions and even extended his range out to 10-15 feet.extremely fair assessment. I remember saying to myself "Oh shit" as Ralvao checked in. and then saying "oh Shit" after he blocked a shot and got a steal.
Everyone keeps saying "his knees", but when I watch Relvao his mistakes seem to be mental, and he needs better hands. I never noticed an athletic issue. And I think that's a good thing, mental mistakes are coachable. It is going to be interesting to see how he progresses.
