Not really a surprise IMO - Greg is probably the second or third strongest big man in the league outside of Shaq and Yao, and now that he's added some non-clumsy and good footwork to his repertoire his strength is even more dangerous. I still remember last year in I believe the first Phoenix game in Portland when BRoy had 52 points and Shaq tried to move Greg in the post.. only he couldn't and he traveled because of it. It made me smile so much.
