In addition to the Power Rankings based on our modified Elo rating system, Sportify will publish an xG leaderboard with total xG as well as total xG conceded per team.
The xG Leaderboard is ranked first by xG total, with the difference between xG and xG conceded as a tie-breaker where necessary.
Sportify calculates expected goals at multiple levels. The two primary values used in analysis are the raw chance quality and the raw chance quality adjusted for the context of the shot, in particular the player taking the chance. The adjustment allows for performance evaluation relative to the expectation of each individual player. The xG Leaderboard above uses the xG values generated by the team.
