I don't quite understand this criticism that he's getting by only on his athleticism. A lot of NBA players rely on athleticism. Until this "career changing injury" or the actual decline in his athleticism actual happens, so what? Yes, he uses his athleticism. It's that athleticism that helps make him dominate as a rebounder and shot blocker and finisher at the rim. "Oh but wait until he's 33 and his athleticism declines." Well , seems like he has another 10 years to use that great athleticism then.
It's not like he's too old to develop and improve those skills. And, in the meantime, he's still going to pull down 15 rebounds a game and block 3 shots a game and still get anywhere between 15-25 points a game. For someone who relies mostly on his athleticism, that's pretty damn good.
