Performance Index

The Performance Index is defined differently for each position, and measured only for each individual league and position; meaning you won't be able to compare values across leagues and positions, and why these options are greyed out from the index tool when Performance Index metric is selected.

After looking at the percentiles within the player's league and position for all these metrics, the scores are combined and then brought to 100 and normalized with each metric weighted for their "importance" on the final score. Minutes played are included to give more weight to players who have affected more games.

Possession +/-

Possession plus minus is a new metric aimed at measuring a player's possession contribution, estimating how many times he wins or loses the ball every 100 possessions.

While we can simply look at a player's "Possessions won - lost", it has a few design flaws and is heavily skewed towards lower-possession teams. Indeed, players in teams that hold less possession have fewer opportunities to lose the ball (for example playing fewer passes on average) and more opportunities to win it back (since the opponent has the ball for longer). Instead, we use:

• Adjusted possessions won = Tackles won + defensive duels won + interceptions, adjusted for 100 ball possessions
• Adjusted possessions lost = Inaccurate passes + unsuccessful offensive duels, adjusted for 100 ball possessions
• Possession +/- = Adjusted possessions won - Adjusted possessions lost
