His coaches have been Brian Hill and Stan Van Gundy.
Orlando's defensive ratings since 2006/07:
06/07 6th
07/08 6th
08/09 1st
09/10 3rd

Do you really think that KG could have lead the Magic to those types of Dr-ratings with the teammates Dwight has had?....
I get where you come from. You see a bunch of guys on both player's teams with meh defensive reputations, and think "How can the difference between them really be that huge?"
Where am I coming from? Start with a realistic assessment of how much impact players have in the NBA.
1) What's the gap between the very best teams and the very worst teams in the NBA? Average difference over the last 3 years:
Offense: 12.3 (points per 100 possessions)
Defense: 11.9
That includes the dream teams and the tankers. One would certainly think that the impact of any one player was only a fraction of that, right? What would you guess?
2) What's the best indicator we have of the order of magnitude of stars? Gotta be APM leaderboards. To be clear there is a weakness with using APM to judge a particular player because of lack of sample size which leads to relatively high variance. But using a leaderboard from a multi-year sample basically fixes all of that and gives us a ballpark for star impact.
So what do we see? Well, Ilardi's 6 year sample from '03-04 to '08-09 yields these numbers for the Top 10 big minute players:
Offense: Top 10 average: +6.82. Std Dev: +1.14.
Defense: Top 10 average: +5.11. Std Dev: +1.04.
So about half the team number, which seems utterly reasonable to me. Again, if the offense can pass the ball to an open man, your defense is screwed. One defender cannot keep that from happening, he needs help. All of this seems to me to be about the only rational way to go about estimating this stuff, and I feel a lot more comfortable with that that looking at sets of teammates and saying "Eh, looks about the same."
