Great points.
The thing is that regardless of which players are actually better or worse, a team's strategy my be shifting apparent offensive vs defensive impact by metrics like this.
A team's strategy can affect a player's overall impact as well of course, but while that's not necessarily the player's fault in terms of what it says about how good he is in the abstract, it does say something real about his on-court value presuming we have enough sample to have confidence in what we see.
ORtg vs DRtg-wise though, all more sample tells us is that the data isn't do to noise, not that it has to be the product of the side of the court it purports to speak to.
I mean Aaron Gordon plays on the same team, has played close to 90% of his minutes with Jokic, the Nuggets score 0.2 per 100 less and give up 0.8 per 100 less with him on the court compared to Jokic, and yet Gordon's DBPM is -0.4, while Jokic's is +4.4, which is 1 better than anyone else in the league. So if there's something special about Denver's offense that benefits their defense, it's not showing up in Gordon's DBPM.
People can come up with whatever side narratives they want that may explain things to some minimal degree, but clearly what is mostly going on here is DBPM is giving Jokic *basically all of the credit* for the Nuggets defense because of his rebounds and steals, because those are what is in the box score (which is what the B in BPM stands for) and not accounting for the various things he does poorly or his teammates do well that do not show up in those two stats or blocks.
It's kind of funny, in that people are putting BPM up like it's a modern stat when it was first made popular like 15-20 years ago before most teams had actual analytics departments and at it's heart really just refers to the same basic box score stats that people were citing 30/40 years ago.
First to be clear, I'm not looking to champion BPM. I used ORtg & DRtg for a reason.
Second: I'm not saying that these defensive stats are necessarily allocating Jokic's offensive impact as defense, only that that is really the only other possibility besides concluding he's have major defensive impact. And yes, if you're talking about a box score stat like BPM then you're talking about other things being in play, but Jokic's statistical thumbs-up on defense is there with or without the box score.
Regarding the amount of time played together, just keep in mind that it's not like Jokic's only separating himself by the box score.
Here's the leaderboard for raw +/- this year:
1. Jokic +588
2. KCP +495
3. Gordon +482
Top leaders from other teams:
4. Tatum +390 (top Celtic)
6. Garland +368 (top Cav)
8. Holiday +340 (top Buck)
(tie) JJJ +340 (top Grizz)
10. Embiid +321 (top 76er)
The most salient thing here is of course how the Nuggets dominate the list.
But the second most salient thing is how big of an edge Jokic has over anyone else on his team. When you see that, unless there's a specific reason to think that there are two roughly identical players that make each of them replaceable within the team context, it's generally an indicator that the guy standing out is the one actually driving the success, and everyone else is considerably less important.
there's also that little thing calld "our eyes" - what i mean is, Jokic is playing as a traditional C on defense.
we don't need some advanced stat to help us seperate Jokic's contribution on that end of the floor from say, AG's or Murray's - we can see how they are being deployed and which roles they are filling
AG covers the tougher forward matchups but anyone who watched him eiher on the Magic or as a Nugget can see that he isn't very good at it. he isn't bad, it's just not anything that is making any serious impact
he rebounds well, contests some..but more often than not he's a non-factor especially when assigned to perimeter players
Jokic is contesting most of the shots, he's the one helping \ recovering and is there when the defense breaks down (like any other traditional C) and he's the one making sure they get more than their fair share of defensive rebounds, not just by rebounding that's obviously part of the box-score metrics but also in boxing out which isn't in those stats.
to make myself clear i'm not saying he is incredible at it - he obviously isn't and Denver for the season is only about the 15th best defense which is what you would expect with him as the main rim protector and anchor of the defense
but be that as it may, it's very obvious to anyone who watched Nuggets games who is the one that should get the credit for their defense, mediocre as it may be

just for reference, Brook Lopez (da real DPOY) is leading the leauge in DFGA (defended FGA) with a whopping 22.6 shots
Nikola Jokic is 2nd (!) with 20.4
Embiid is 3rd btw with 19.1
again, to avoid confusion - both Lopez and Embiid are obviously better at this aspect of defense and it's evident by opponents shooting about 46.5% when they contest the shots while Jokic is at around 50%
the rest of the top 10 are in this order: #4 Sabonis (who has the worst % among the top 10 in DFGA at almost 54%), Gobert, KP, AD, Zubac, Mobley and Turner
Turner and Zubac have a worse % than the Joker and he's defending more - wrap your head around that
and that's obviously not his strong suit, he excells in other aspects of defense even tho he is def mediocre (at best) in this one
all these guys (with the exception of Mobley) are tasked with anchoring their team's defense as Centers
that's why we don't need some magical stat to seperate AG or MPJ from the Joker - it's plain to see
obviously defense requires cooperation and commnication and is alot more complicated then who stands under the basket and who doesn't, but the reality is the Joker plays a huge part of Denver's medicore defense
if you replace AG or Murray\MPJ (Murray is just bad this season defenseively) you would get about the same results
none of these guys are very significant defensively (or good), without Jokic's rebounding, rim protection, defelctions, i.q and the offense turns to defense stuff - Denver is not a playoff team!
and yes, if you replace the Joker with a better defending C then obviously the Nuggets defense will improve but unless he's some two way elite Center (how many of those are around?) their offense will crater to be amongst the league worst
imagine Murray\KCP\AG\MPJ + Porzingis or Turner
that's not a playoff team imo
