When you factor pace and playing time, his numbers are still awesome, just not that awesome. However, some things must be factored: he's not such a good offensive rebounder, his defence is iffy, although I think he does a decent job when paired with players of his size, D'Antoni's system is great for a player with his skill-set.
Still, a very solid big, who hustles, finish well around the rim and is terrific running the pick'n'roll, being effective and efficient without stopping the ball or being the focal point of his team. Great player if you don't value shot creation and interior defence; otherwise just good. I do believe he'll get a bigger contract than he deserves though.
