Advanced stats have rebound rate, assist rate, turnover rate, block rate, steal rate, etc. . . all to take the effects of pace out of the equation (and other reasons) and allow you to see the "true" rate at which NBA players perform that particular stat. So, why no scoring rate so we can see what percentage of points being scored are scored by a particular player? (not hard to calculate but neither are any of the others)

I'm 100% with you. As you know, I do calculate a "scoring" rate just about any time I look at scoring. Furthermore, I look looking at scoring "share" as well (the % of team's points a player scores). Why?

-PPG isn't entirely instructive.
-PPG + TS% is fairly instructive.
-Pts/75 + relative TS% even slightly better. It's especially better comparing across seasons.
-Pts/75 + relative TS% + scoring share is even better.

The last one, one quick glance, allows me to know the "rate" a player scores, with what efficiency, and how large of the scoring load he had to carry for his team. This last fact is obviously important when compared with the first two, because the higher the scoring burden on one player, the more we can assume that one player has to operate in a "unipolar" scoring sense, which will affect his efficiency.

To me, if we see a high pts/75 (eg 30), a high efficiency (eg +5%) and a high scoring share (eg 30%), we can quickly say "wow, that's an elite scorer."
