Unlike the SciSkill index, the Contribution Ratings metrics are not tailored for a cross comparison of players in different leagues (yet). A player with high offensive contribution in the Italian Serie B, cannot be compared 1-on-1 with a player that shows high offensive contributions in the English Premier League. However, the Contribution Ratings metrics can provide you with crucial context when it comes down to assessing players, as we discuss below.

The Contribution Ratings metrics provide insights into how a player contributes both offensively and defensively to the performances of their team. Furthermore, the module in the platform shows how each player ranks on different aspects of the football game compared to all other players in the same position in the same league, normalised to a per 90 minute basis.

Offensive Contribution Ratings can, for example, tell you that a certain player does not contribute that much to their team’s offensive game, but does belong to the most contributing passers in their league (of all players on similar positions). On the other hand, a player who hardly ever shoots on goal (and thus is more likely to score low on Finishing) might still rank well in certain areas of Offensive performance.

Considering the Defensive Contribution Ratings, it could occur that a player belongs to the most contributing tacklers on their position in the league, while not contributing that much to their team’s defensive game overall (compared to players on similar positions). Also, players who belong to the least contributing tacklers in the league can have a relatively high overall contribution to their team’s defensive game.

Next to the relative contribution a player has to their team, Contribution Ratings also provide insights into the specific qualities of a player. Does a player score relatively high on Dribbling in their league? Then you can assume this is one of their core qualities. Is a player showing relatively low contribution on certain aspects? Then this can indicate it’s either not one of their qualities or that he rarely makes use of this quality during matches.

Contribution Ratings give you a quick overview to find the highest offensive or defensive contributing players in each league based on totals or specific qualities. Depending on the qualities you are looking for in a player, you can use Contribution Ratings metrics to assess whether a player shows these qualities on the pitch.
