He was impressive, but I'll always take his young-star-at-forward Suns predecessor, Antonio McDyess, over him. I trust *his* defense, and he was no Amare Stoudemire no slouch in scoring. I'm not sure whether he was that athletic overall, but he probably could jump at least as well.
As for the prospect of a defensive coach teaching Stoudemire to play defense: a question occurs that I think I had thought of before. Why did he never absorb good defense from his equally athletic frontcourt mate, Shawn Marion? Since I'm no fanboy of Shawn Marion, I have no problem entertaining the idea that Marion was over-rated; but to claim Marion wasn't a good defender is difficult to believe.
