Why is it that a team full of good and some great defenders in Boston drop off so much without KG. It doesn't make sense to me that Thibs couldn't make the Celtics good defensively without KG when he has made the Bulls great defensively without KG.
I don't discount the plus minus numbers. My issue with +- is it doesn't predict future results. At times its all over the place. I don't think you can justify a stat's worth without it having some level of ability to say what will happen in the future.
Also when someone says Lebron's adjusted numbers went down because he now playing with Wade. How exactly does that reflect on Lebron as an individual player?
This is like the same discussion I had with John Hollinger. I'm on him about how the PER of players on slow pace teams gets inflated. All at the same time slow pace teams utilize there superstars at higher usage because half court basketball usually benefits the stars. On the flip side players on a fast pace team get there PER deflated because it assumes they are using more possessions. Even though just because a game is more up tempo doesn't mean your going to get more opportunities.
He agrees with this and After a while he comes back that PER really isn't good to compare players on different teams. Yet the entire world uses PER to compare players on different teams including him.
Now I go to adjusted plus minus. I see the importance of what adjusted plus minus does. If the conclusion was only KG was very important to Boston and Minnesota I be fine with that. When we get to the point that other players aren't as good because they don't have as good a +- then IMO things are out of hand.
The biggest thing about any stat is there are reasons why things occur. Rotation patterns, backups, coaches philosophy. Not to mention some superstars may just have a bigger involvement in a teams game plan than others. There are more elements to why things happen on the court than his teammates suck more than another players teammates.
There is a lot in this post that sounds reasonable. But again, at least IMO, the arguments that you make could very easily and reasonably be reversed and used against the position that you are defending. Consider, throughout this thread you have consistently said that the biggest issue with using APM (specifically defensive APM) to say that KG is the best defender of his generation is that, to you, it is a single data point and that it doesn't support the rest of the facts as you see it. And that you don't think it's right to depend on a single stat to make a case when it runs counter to everything else. Reasonable. The only problem is, that seems to be exactly what you are doing...just using a different stat.
On these boards, there are essentially 4 types of evidence that can be used to make a case: team results, accolades, statistics, and opinion (i.e. "I watched the games"). While watching the games in some ways gives the best understanding, it is also the most subjective and least conducive to a debate. Essentially, opinion can help shape your case but it can't make your case. So, for the moment, let's look at the other 3 methods. And also, since we're talking about KG, let's break it down into Minnesota vs Boston years as we discuss his defense.
Minnesota: when KG was in Minnesota, as you've pointed out often, their team defenses were generally in the average category. So, in the "team results" section of the Minnesota years, KG's Wolves don't compare with some of the team results of other defense legends. Fair enough. Now let's look at accolades, the "second" type of evidentiary support...in Minnesota KG was named first team All NBA Defense 6 times, with 3 top-3 finishes in the Defensive Player of the Year vote. If his career would have ended right there, that would have made him one of the most decorated defensive players in NBA history. So, he did well in defensive accolades in Minnesota. Then, with defensive stats, you have KG measuring among the leaders in the B-R stats (DRtg and Defensive win shares, both heavily influenced by team results) and KG lapping the field in defensive adjusted +/-.
So, leaving opinion out of it, you had KG's Wolves measuring average on defense as a team but KG as an individual with both the accolades and defensive stats to suggest that he was right there with Duncan and Wallace as the best defensive players of his generation.
Boston: since KG has been in Boston, the Celtics have consistently had one of the best defenses in th eleague. So in the "team results" section of the Boston years, KG's Celtics compare with any of the greats. Then we look at the accolades, and in Boston KG has been named first team All NBA Defense 3 times in 4 years and has 2 more top-3 finishes in the Defensive Player of the Year vote. Then, in the defensive stats, you again have KG measuring out among the leaders in the B-R defensive stats and lapping the field in defensive adjusted +/-.
So again, with no opinion and no real interpretation, KG's Celtics measure elite on defense, and KG as an individual has both the accolades and the defensive stats to suggest that he has been right there (this time with Dwight Howard) at the top of the "best defensive player" debate of the last four years.
Conclusion: See, your stance has been that APM is the outlier that can't be trusted because it suggests that Garnett is clearly the best defensive player of the past 8 years. But you've been basing the majority of your argument on the fact that the Minnesota team defense was average. And if you look at the 6 non-"our-opinion" based facets of the Minnesota and Boston years I just wrote down, you'd see that 5 of those 6 areas suggest strongly that KG is on the extremely short list for best defender of this generation. If we completely throw out the 2 stats under contention (Wolves' team DRatings and KG's Defensive APM), the remainder of the evidence we have would put KG in a conversation with only Duncan, Wallace, Howard (half generation after) and Mutombo (half generation before) for best defensive player of this generation. So even without defensive APM, KG would still be on the EXTREMELY short list for best defensive player of his era.
So to me, it's not the defensive APM mark that is inconsistent. That a player that in every other way is considered one of the top-5 defensive players of his era measures out as actually the best is actually down-right intuitive. The stat that is much less intuitive, based on the other results in play, is that of the Wolves' team defensive ratings. By far, that is the result that to me stands out as the "odd ball" and the one that should be held to a higher standard of proof. By all means, I would (and have) participate in a vetting of both the Wolves' team defensive results AND the individual defensive APM measure. Interpretation and analysis are vital to any argument or stat usage, and I wouldn't suggest we use any of them in a vacuum.
But again, your aggressive stance that defensive APM suggesting that KG is the best defender is in some way out of touch with the rest of the story is...frankly not correct. It's entirely in-keeping with the rest of the results. The part that is disconnected from the rest of the data is the Wolves' team results, which to me are very explainable when you start looking at the rest of the cast. And when the entirety of the rebuttal thus far has been essentially "the cast couldn't have been that bad"...I'll just say that I don't think that's the strongest case that could be made, and to thus hang so much of your stance on the Wolves' team results isn't necessarily the most reasonable argument to be made in this thread.
