He plays as hard as ever, but sadly, he has lost a step. I haven't seen him face his man up and power into the lane for a dunk since he's been with the Nets, and he's not the shot blocking force that he was. I'm not sure how much is due to his kidney condition, how much is due to his long lay off, and how much is due to the fact that he is 33 - all he I know is that he is not the same Zo. That being said, come playoff time, there is still no other center in the east that I would rather throw in against Shaq... Zo can still bang.
