Hard to say if he's feeling healthier or just simply playing better. Early in the year, he wasn't getting many minutes even though he started. He'd have some 4-point, 3-rebound games in under 20 minutes as the Wizards let their younger bigs play in blowout losses (Seraphin and Blatche, primarily).
The pairing with Nene at the 4 seems to have been effective, and now he's a crunch time guy getting 35 minutes a night.
His shot blocking isn't what we remember, but he's still every bit the rebounder. And sometimes now he shows that feathery touch again that he left here with -- that hasn't always been there in the pros.
