Nice hands, long arms, and moves well for a big guy. Shot looks good and he is relentless on the boards, although he was at least 4 or 5" taller than any opponent. Playing "above the rim" is overrated. It looks good on highlights, but it seldom wins games.
Yeah.....that's hard to teach. That's work ethic and character. Those are traits that will take natural talent a long long way.
