I try to look at things with some context, though I know you'd like to throw it out to fit your agenda.
I've seen some other cherry picking too trying to discount stats but the stats are used the same way for everyone....and there may be some surprising results.
You also have to take into consideration that this isn't a widely used stat, being touted by the dude who invented it and it's got some strange, unclear calculations going on.
I tried to provide some context with my post. I'm not sure what value it brings over DPM, DWS, or DRtg - which all have their own flaws. The fact that it's really hard to find an NBA big man with a negative DPIPM is odd to me (the one I recall from the spreadsheet was Marreese Speights). Also the fact that arguable 4 of the top 5 players in the NBA don't have positive DPIPM makes me question how necessary a metric it is for NBA success.
Well you are talking about 4 of the top offensive players. All the advanced metrics show LeBron has been a terrible defender this year and it's never been a strength of Curry and Harden. I mean in the spreadsheet you linked it's obvious their net impact is still among the highest in the league because their OPIPM is so high, so combined, they still are that high.
You are right that it's not necessary for someone to have a positive impact without defense, and I definitely think Ayton will have a positive impact even if he is a poor defender, because his offense will be so good.
The fact that it is really hard to find a big man with a negative DPIPM in the NBA, combined with the fact that Ayton DID have a negative one is a bit alarming though...particularly against college competition.
I agree that the calculation is pretty complicated. It's been pretty widely accepted though. I mean if you look at most of the people who grade out the best on offense and defense in the NBA, it looks fairly accurate to me.
I've never seen anyone reference this calculation other than this dude on his own website/twitter account. Maybe forum goers are adopting it, but I'm not buying it, especially as a predictive model.
