viewtopic.php?f=344&t=1048645&start=0I think that's where Bill Russell's argument comes from. Especially from 61-65, but as pointed out by ElGee, Russell basically played GOAT defense his entire career, so his longevity is pretty insane.
If we average the 61-65 stretch, Russell's Celtics were a -9.5 defense over 5 years. Incredible.
Now, Tim Duncan is a guy that routinely gets compared to Russell's Celtics, and he's really the one defensive anchor who enjoyed great defensive teammates and a great defensive coach his entire career, just like Russell. So let's look at his team's DRating throughout his career:
98: -5.6
99: -7.2
00: -5.5
01: -5.0
02: -4.8
03: -3.9
04: -8.8
05: -7.3
06: -6.6
07: -6.6
08: -5.7
09: -4.0
10: -3.1
11: -1.7
12: -1.4
13: -4.3
14: -4.3
Well then, let's average out Duncan's best 5-year stretch: 04-08. Over that time period, the Spurs were a -7.0 defense over 5 years. Fantastic, but still significantly behind Russell's Celtics (-9.5). But again, it's no secret that the Spurs play in a much better offensive era. It's very possible that Russell's Celtics would have dropped to a -7.0 defense during their heyday as well.
And one more point I'm curious about...I understand we don't have a lot of individual impact numbers for Bill Russell, but a really common counter-argument to "Tim Duncan anchored so many fantastic defenses!" is "Look at his teammates and his coach, he clearly had more help than someone like Kevin Garnett or Hakeem Olajuwon, it's not fair to prop him up over them based on team defensive ratings"...but we feel alright giving Bill Russell all the credit for the Celtics' defensive dominance, despite playing for Red Auerbach, and despite playing with many notable defenders on his team?
So first off, when looking to evaluate the dominance of an outlier it's not actually good to compare them to the mean because they distort the mean. This is particularly the case in a smaller group.
So for example, in '64, if you compare the Celtics to the median, they rate a +12.8, and if you compare them to the mean of the team's not including them it's still a +12. Basically then the Spurs have only 1 year even 2/3rds as dominant as that, even before you consider that a 12-13 edge relative to efficiencies south of 100 makes for a great percentage edge that it would in later eras with higher average efficiencies.
So yeah, just peak vs peak, there's absolutely no contest here. We can talk about degree of difficulty, we can talk about luck, but just the numbers, Russell's Celtics hang'em up there off the charts.
Re: Russell sharing less credit. I don't mean to imply that Russell should get all credit while everyone else shares.
If you're wondering why I consider Russell the defensive GOAT while leading the defensive GOAT team but I don't consider Duncan the 2nd while leading the 2nd, well clearly there are other factors involved. I will admit as always that with players from earlier era I accept things more on face value, not with high confidence of course, but I'm not going vehemently deviate from history based on nothing.
I will also say that when we talk about a particular team outlier, it makes sense that the reason for it might to have much to do with a particular star talent. After all, if it's not due to that, then what's it due to? GOAT defensive strategy from the coach? Red's good but there's nothing to indicate this. GOAT and a half defensive supporting cast? Sure is convenient it came and left with Russell.
