Productivity per game
Player Total Contribution (PTC) is an index to evaluate the performance (production) of basketball players which is based only on box-score data, and it has been validated using several procedures (Martínez, 2019).
PTC = 1 PTS + 0.91 BLK + 0.58 DRB + 0.92 ORB + 0.86 STL + 0.48 AST + 0.23 FD – 0.91 MFG – 0.57 MFT – 0.86 TOV – 0.23 PF
Where: PTS: points made; BLK: blocks made; DRB: defensive rebounds; ORB: offensive rebounds; STL: steals; AST: assists; FD: fouls drawn. MFG: missed field goals; MFT: missed free throws; TOV: turnovers; PF: personal fouls made.
Important note: Recall that PTC does not take into account the moment of the game where the actions occur. I have proposed a new way to compute the weight of each action based on estimated possesions left, score differential and time remaining (Martínez, 2019). However, the real implementation of that procedure is not available yet.
