That's not the sort of thing voters will understand, but as analysts its clear that Durant basically has the edge everywhere you can possibly look.
I just want to point out that this isn't true. The MOV regression data leans towards James (I don't see the utility of NPI RAPM with a 55 game sample). Box-score regression leans in Durant's favor (J.E.'s SPM incorporates some more variables than the traditional stuff). Only two hybrids, one prefers Durant, and the other has them even (though mystic posted his numbers prior to James getting this tear going).

Well, it's good you responded and gave these other points of you.
I'll re-phrase:
All stats that rely solely on this year's +/- data show clear signs of Durant being much more impactful than LeBron.
Data that relies on priors sees this edge completely disappear. Basically telling you that if you go in assuming LeBron's making everything happen based on previous year, the actual machine learning won't show any indication that there really isn't any correlation to speak of when looking just at this year.
Some would argue undoubtedly that this is why you need prior-informing so that you don't overreact to small sample size. However, given Durant's clear superiority in box score metrics, LeBron showing clear signs that he's coasting, and how shocking it was that Durant did what he did with Westbrook out, to me all this is just showing why it's problematic to only look at prior-informed data.
The methods geared toward giving us the best results on average over the NBA do so with more convoluted approaches which at times can lead us far from the mark.
