05 Spurs: -7.3
99 Spurs: -7.2
11 Celtics/Bulls: -7.0
07 Bulls: -6.9
But what we need to factor in is that Duncan missed games during his 2 best seasons. Here are the defensive results in those games:
2004 (13 games missed):
with: 92.8 D rating (-10.1 rel to LA)
without: 101.0
Diff: -8.22
2005 (16 games missed):
with: 97.9 D rating (-8.2 rel to LA)
without: 102.6 D rating
Diff: -4.74
So if you adjust for that, they have by far the best defense in NBA history when Duncan plays in 2004 (1.5 pts/100 ahead of 2nd place 08 Celtics). The 05 Spurs move to 4th place all-time after adjusting for Duncan's injury. And this is without David Robinson. I would venture to say that Duncan was still the best player in the NBA in 2004. Duncan also missed 2 games in 2006 that would have moved the Spurs to -6.9 which is right around top 10.
Again, this needs further analysis. Let's control for Tony Parker in 04 and look at the 74 games he played:
2004 Spurs
64g w Duncan: -8.5 DRtg -- OREB% 29.4% DREB% 75.5%
10g w/out Duncan: -5.1 DRtg -- OREB% 32.4% DREB% 73.3% **Replaced by Malik Rose
Let's control for Manu in 05 and look at the 74 games he played:
2005 Spurs
61g w Duncan: -7.8 DRtg -- OREB% 28.7% DREB% 74.4%
13g w/out Duncan: -2.5 DRtg -- OREB% 29.0% DREB% 72.4% **Replaced by Robert Horry (11 of 13)
I actually see these data points as evidence for just how solid the defensive team/scheme around Duncan was. Keep in mind I think Duncan is a marvelous defender, but if we "believe" the numbers for a second (ignore error/variance which is present in this size sample) we see a 5 --> 8.5 shift by replacing Malik Rose, and then a 2.5 --> 8 jump by replacing Robert Horry.
I'm also inclined to agree with what others have said about 2004, which is it was a weird year with injuries and applications of rules, which probably led to some of the weird team distributions we see that year (eg Pistons, Spurs, Mavs).
