Sure, but it’s not like the best offensive player has these crazy defensive stats every year. He’s just vaguely making an assertion so again I’m not sure exactly what I’m refuting but I really doubt being a good offensive player has anywhere near the impact on these stats compared to him having great rebounding numbers and a high steal rate for a center so the metrics assume he’s prime Olajuwon on defense because that’s a huge portion of what it has to go on from an individual statistic standpoint.
have you considerd not all good offense is created equal?
example A. - a player scores within the flow of the offense, with members of his team already starting to get back on defense before the play is even done
example B. - a player scores in a drive but ends up on the floor while the opponent inbounds and starts a possesion after a made basket but - 4 on 5 on the floor
see what i mean?
playstyle, i.Q, statetegy etc. are all in play
not all great offensive players have an innate "fixed" contribution to their team's defenses that's true
but some do more than others and like I said - in the rs, Jokic has clearly been that guy
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.
