The ins and outs of the Sportify Fantasy scoring engine

There are two scoring engines in the forthcoming Sportify Fantasy game, one for goalkeepers and one for outfield players. Both are tied to our approach to expected goal value, which you can read about here.

 

Goalkeepers start at 50 points and are then scored on five regular categories of actions (though certain categories are buckets of actions) while two other irregular actions can also affect their score. The five core pieces are: sQxG saved, good keeper actions, bad keeper actions, significant errors and goals conceded. Penalties for conceding goals are mitigated based on the sQxG of the goal. Good actions, bad actions and significant errors are outlined in Table 1.

 

Goalkeepers also earn points for saving a penalty kick but are punished for not completing the full 90 minutes, especially so if the failure to complete the game is due to a red card.  

 

Goalkeeper scoring details are as follows:

The outfield players’ scoring engine is made up of three separate scores: offense, possession and defense. Offense and possession scores each start at zero and have five categories, all of which are individual player statistics. Scoring statistics for offense are goals, assists, cQxG of shots taken, cQxG of shots assisted and finally second assists. Details are below:

The five categories comprising the possession score are duels won, possession ends, successful final third passes, pass completion rate and contribution to possession in the buildup to a shot. Point assignment and further details are below:

Players’ defensive scores start at 25 and are then calculated using five individual player categories, as well as three team statistics. These team elements are added because defense is more of a team related activity than offense or possession. The three team level statistics are goals conceded, opponent cQxG on target and high quality chances conceded. The five individual categories are mostly buckets of individual defensive actions: two tiers of good defensive actions, two tiers of bad defensive actions and, finally, cQxG blocked by the player in question. Details of the eight categories comprising the defensive score are as follows:

Finally, the outfield player’s overall score is the sum of the three scores detailed above.
