- from the article linked above - "...The first step is to match the offensive player with their corresponding position. To do so, I used Krishna Narsuâ€™s ( @Knarsu3) positional estimates, based on Basketball-Referenceâ€˜s play-by-play data. Krishna Narsuâ€™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."

I have then taken this number and converted it to a scale from 1-100 with 100 being the most veratile defenders, and 0 being the least versatile.
