The numbers are in for Week 17 of the MLS season. Below you can find the top 20 players, according to the Audi Player Index, as the league gets past the halfway mark. 


The index is calculated by rating nearly every action on the field according to the amount of positive or negative impact on the team's success, taking into account the position of the player, key tasks and the place on the field where the action takes place. The most influential play possible is a goal from outside the box, which would give a forward 545 points.


Here are the rankings for Week 17:
