First; Great post and addition to the thread, you raised some valid concerns about the op.

Hi Caliban, I really appreciate the thorough write-up, and I really, really value the way you link to the sources for the figures you quote. That's serious, top-notch research presentation...
The "but" is that it feels a bit like you have a different stat for every player, and a lot of them feel chosen to reflect you narrative. If you think RAPM is the right measure for Wade, for example, then it's probably worth mentioning that Tyler Johnson also rates out as a net negative by that measure, while Gerald Green doesn't - rather than pointing in another direction when you get to him.
I do not feel like RAPM is the right measure for Wade, Johnson or Green. If I had to choose one I'd pick BPM (you?) but I don't have to luckily. A good blend outperforms them all in solitude as far as I've seen, and a blend is also what I'm leaning on when considering player impact by numbers. Outside of that I also try not to compare players with different roles say for example; Wade, Johnson & Green as you though would be what I should have done? (or did you write it to just raise the question?). To me the numbers simply captures how well they did their specifik task, and regarding Wade, how well he executed the 1st banana role. And the answer to that is not very well.
So then, why did I chose to highlight RAPM and not say ws48 or BPM for Wade? Two things. 1) They all tell about the same story, Wade's impact on the game is about starter to low end starter at this point (BPM ,8 & ws48 at ,105) and more importantly, non of them answers my initial question "
Is Wade’s production worth 2 years, $47.5 million at this point?" in a notable divergent matter than RAPM does. Because of this and 2) time constraints I simply chose not to. You made me realize that I should have included them for a broader picture and that it actually would have help my point or narrative if you so choose.
If a stat is one of general application, like RAPM, then if you believe in it you don't need "rim protection index" and if you don't then it probably doesn't tell us anything useful.
As I stated above and now should be clear I do not consider RAPM or any other stat in singular to be a good way to go.
The choice of RAPM and "rim protection index" in the case of Hassan was to imo best display that Hassan, as the season went along, bettered up on his most glaring weakness. This weakness was also often rightfully raised by his detractors, namely that Hassan's chase for individual blocks was a detriment to the teams defense. While he still does this too much and still could help the defense more than he's done so far, we now can conclude that the defense last season at least was better while he was doing it. I could and should have made this connection better.
And no, I do not think the "rim protection index" has any value standing by it's own and barley in combination either. It simply tries to answer how well a players protects the rim, not if that protection helps the team win which should be what in total is the goal of one's evaluation.
I can see the appeal in marshalling all the evidence and letting the reader decide, but mostly I think it's worth pointing to consistent measures across the whole roster. You seem pretty committed to Wade's RAPM, and pretty open minded about everyone else's - it's hard to justify Whiteside's money if he's not a top 80 player at his age, for example...
I think I've answered this indirectly in the parts above and of course it's hard to justify Whiteside's money
if he's not a top 80 player at his age.
Hopefully I manage to straighten out some question marks and please, do not write another solid post I feel obligated to answer as well as I can in a language I do not master. Takes me forever.
