CraftedPM

Crafted Plus Minus | ((standardizedRPM x 5) + (standardizedPIPM x 5) + (standardizedRaptor x 7) + standardizedBPM + standardizedMYRPM + standardizedMYPIPM + standardizedPredator + standardizedPredator + standardizedPPIPM + standardizedLARAPM + standardizedLA3RAPM) / 25 An aggregate of many different plus minus metrics. First, we convert all variables to the same scale, then we combine them and divide by the number of variables. We then take this number and convert it to the MYRPM scale.

Multi Year Crafted Plus Minus

(standardizedRPM + standardizedPIPM + standardizedRaptor + standardizedBPM + standardizedMYRPM + standardizedMYPIPM +(standardizedPPIPM x 3) + (standardizedPredator x 7) + standardizedLARAPM + standardizedLA3RAPM) / 18

An aggregate of many different plus minus metrics. First, we convert all variables to the same scale, then we combine them and divide by the number of variables. We then take this number and convert it to the MYRPM scale.

Passer Rating

(standardizedOffensiveLoad + (standardizedAsttoLoadRatio x 2) + (standardizedAsttoLoadRatio/Position / 2) + (standardizedTurnoverRatio x 2) - (standardizedCreationtoLoadRatio x 2) + standardizedHeight)

We take this number and then convert it to a 1-10 scale. Both this and our Portability are simplified versions of the one's created by Ben Taylor from Backpicks.com Check him out, he's great.

Portability

(standardizedTS% + (standardizedShooting Proficiency x 2) + (standardizedCraftedDPM x 1.33) + (standardizedPasser Rating x 2) - (standardizedOffensiveLoadFromMean x .5) - standardizedBoxCreationFromMean)

We take this number and then convert it to a 1-10 scale. Both this and our Portability are simplified versions of the one's created by Ben Taylor from Backpicks.com Check him out, he's great.

Nylon Calculus - Krishna Narsu & Patrick Miller

Versatility Rating

- from the article linked above - "...The first step is to match the offensive player with their corresponding position. To do so, I used Krishna Narsu’s ( @Knarsu3) positional estimates, based on Basketball-Reference‘s play-by-play data. Krishna Narsu’s table is available here.

I then calculated the percentage of time a player spent guarding each position, and squared the percentage for each position. The sum of the squares for each player is their raw versatility rating. Following the summation, I took the square-root of the raw rating in order to reduce the distance between the most and least-versatile defender (taking the natural-log would work as well), and normalized the data so the maximum number is 1. The smaller the rating, the more versatile defender."
