Part 1 of this series on a new playmaking metric PLAY, we gave an overview, and discussed marginal contribution, which is basically some form of WOWY. See here for Part 1 and here for the full paper. In this part, we’ll discuss competitive and altruistic contributions. Altruistic contribution is what we’ll use to compute PLAY. Competitive and Altruistic Contributions So we have this WOWY for every player, and we are going to decompose it into two parts, competitive contribution (Comp) and altruistic contribution (Alt).
