David Accam’s influence on the Chicago Fire’s first match of the year was apparent to any casual observer. But thanks to MLS, there’s a handy new tool to quantify his performance.

Earlier this year, the league introduced plans to roll out the Audi MLS Player Index for the 2016 season, and the first round of results are in following the season-opening #SoccerSunday extravaganza.

Via MLS, 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, the position of the player and and key tasks and the place on the field where the action takes place. There is no ceiling for how many points a player can score per game. However, previous match play experience has demonstrated that the scores of the best player vary in a range between 500 and 1600 points (the highest score received to date was for Robert Lewandowski [3330 points] by scoring 5 goals in one game).

A threat to the opposition throughout the match Sunday, Accam created Chicago's second goal when he dispossessed NYCFC's Frédéric Brillant and fed Kennedy Igboananike in the 49th minute. He later scored from the penalty spot for the Men In Red, giving him 11 goals and three assists in 25 career appearances (22 starts) for the Chicago Fire.
