I came across a system online nearly 20 years ago, and have saved the formulas. Nowadays, It is hard to find a link to the guy who invented this, but his name was Prouty and he used to calculate these numbers back in the 90’s in the ACC and he usually matched up with all-conference teams and players of the year, so I give him credit for these formulas.
This system takes away any subjectivity and is all statistical based, which I like and takes 4 factors individually and then averages them out to get a final number:
1) Offensive Efficiency
Tot Pts / ((FGA x 2) + FTA) – Measure how efficient a scorer you are, you get bonus credit for making a 3 and having a strong FG and FT %. Basically how many points you get vs. shots taken.
2) Total Offense
Pts + Assists*2 – TO / Min Played
Gives credit to making assists (guards) and balances with pure scorers, and you lose points for turning it over.
3) Possessions Gained
(Rebounds + Steals + (Blocked Shots/2) – Fouls) / Min Played
Logic is not every block results in a possession so you get 50%, but any rebound or steal gains you a possession and fouling gives it back to your opponent (or they continue with a new possession)
4) Win %
Min Played / (Total Team Minutes / 5) * Team Win %
If you play lots of minutes, you are critical to your team, and if team wins games, you are contributing to wins.
