CP3 had amazing offensive impact, but Dwight had an even bigger defensive impact with his team finishing top 3 in defense in all three years that could be considered his peak despite really bad help on defense compared to CP3's team finishing 5th in offense in 2008 despite having pretty good support. Dwight was also the focal point of the Magic's offense whereas CP3 doesn't impact the game that much defensively. It seems like Dwight's D > CP3's O and Dwight's O >> CP3's D.
Dwight's plus or minus isn't as good, but it seems like that's more about him having good backups while CP3 had bad backups. When the Magic's backup center was bad like this year, Dwight's plus or minus was terrific.
I appreciate your civil tone Jazzfan12. You're welcome to ask any questions you want - even if they imply we're wrong - as long as you're nice about it.
So I feel like I'm a broken record at the moment because of the data set I'm playing with but here's some +/- data to consider.
A few notes:
1. This is RAPM, which means there's no explicit bias based on teammates. it's true that if you're simply working with players you don't fit well with that will hurt you and nothing's perfect, but take a look at the values and see if you really see an issue relating to Gortat.
2. This data is from Engelmann, he uses prior seasons as part of his algorithm for a given year, so it's my opinion that any year you think a player had a huge jump in his impact, he might be a bit underrated.
3. The numbers I'm posting are variance-adjusted to try to make for apples to apples comparisons. They are not meant to literally be the points a player is helping his team get, but rather how many standard deviations above a zero rating he is.
'07-08
Howard +1.47
Paul +1.34 (huge jump for Paul in play, probably underrated by this metric)
'08-09
Paul +2.59
Howard +1.52
'09-10
Howard +2.36
Paul +1.60 (Paul gets hurt)
'10-11
Paul +2.61
Howard +2.47 (Gortat traded midseason)
'11-12
Paul +2.77
Howard +1.89 (Howard's flying circus)
So what I see when I look at this is that we have two players who basically have the same 5 year peak ('08 to '12). In those years Paul has the +/- edge 3 of 5 years. Such an edge isn't exactly jawdropping for Paul, but some things to point out generally:
1) If you just feel like Howard's GOT to be more impactful because of his 2-way impact, we don't see any such separation at any time. This isn't to say Howard's defensive numbers don't beat Paul's. I could list those out but Howard beats Paul every single year on defense. The overall impact though isn't showing Howard having the clear overall edge.
And in truth this relates to a general trend: The defensive stars don't matter as much as the offensive stars. Not that defense isn't as important as offense, but we just don't see defensive guys equaling the impact of offensive guys. This is a modern thing certainly, but it is a thing none the less.
Of course with that said, this stat LOVES Garnett. If you were to really to take it as the definitive statement of who the best players were, the best player of the last decade was a debate between LeBron & Garnett, and Garnett was doing this in part because he put up defensive numbers significantly better than even Howard's.
2) Do we buy that Garnett's impact on defense surpasses Howard's? Well, I do, but let me speak to some objections I know people will have:
- In Howard's Orlando heyday, their defense was excellent. Surely that's not a coincidence, right? No but yes. Howard was a significant part of making that happen, but the data's been telling us generally that no one man can make a defense good...which relates to why we saw serious falloff for the Magic last year.
- Doesn't Gortat distort things in some way? I understand a lack of faith that this system can truly normalize for Gortat, but look at the data, do you see signs that it was getting majorly thrown off by Gortat? I don't.
3) Has to be noted that the only two years where Howard beats Paul, there are very legit reasons to think that the numbers don't capture Paul's healthy impact. In '07-08, Paul took his big leap and thus was probably underrated by Engelmann's prior influenced system. In '09-10, Paul was hurt.
To me the numbers clearly seem to be favoring Paul.
4) With that said, the difference in peak values for these guys isn't exactly a blow out. +2.77 vs +2.47, I'm not going to argue that you should have so much faith in this system that you should take that lead as too big to side against.
