PCR Primer:
PCR is a simple metric constructed to evaluate NBA players on a statistical level in their season performances. It is quite similar to other ratings of similar natures, such as PER and Game Score. Positive weights are given to stats such as Points and Assists while negative weights are given to negative stats such as turnovers or missed shots. PCR is also the cornerstone of my Estimated Wins Contributed which will be explained in detail in a soon to come blog post.
The Formula is as follows:
PCR= (Pts+Reb+(Ast x 1.4)+ (Steals x 1.1) + (Blocks x 1.2)- (Missed Field Goals+ (Free Throws Missed x .5) + (Turnovers) + (Personal Fouls)/ Games Played
Total PCR= Previous formula without dividing the total by games played.
PCR/36= Total PCR/Minutes Played x 36
Rationale Behind Different Weights:
Assists x 1.4: Assists are given more weight than rebounds due to the fact that rebounds happen at much higher rate than assists, for example for every one assist this past year there were 1.9 rebounds. One of the major flaws in other metrics of the same type, is that they overvalue centers. Mine does to a certain extent but not as much as others. The reasoning behind the weight boils down to the fact that getting more than 10 assists is much more impressive and rare than getting 10 rebounds.
Steals x 1.1 & Blocks x 1.2: I added these weights to give more emphasis to defense. The issue still prevails as it does with an box score metric, defense is hard to quantify. Blocks are given more weight than steals because blocks usually correlate with higher defensive performance while a player can make risky defensive decisions and still rack up steals (James Harden).
Rough Guidelines for Evaluating PCR:
30+: MVP Level
27+: MVP Candidate
22+: All NBA Level
20+: All Star
18+: Borderline All Star/Good Player
15+: Good Player/Solid Starter
12+: Above Average Contributor
8+: Average
6+: Subpar Player
<5: Non Factor

I apologize for any typos within the spreadsheet in advance, this is from my excel file therefor I was not cautious regarding the exact spellings of players’ names.
