The Club Possession feature allows you to adjust a player's statistic values based on the average possession of their club, compared directly to your club's average possession. You can input a possession percentage for each club as well as for your own club, ranging from 0% to 100%.

When a player is from a club with a higher average possession than your club, their Defensive based statistics will be increased. This is because they are expected to spend more time off the ball in your setup, offering greater opportunity to perform defensive actions such as Tackles, Blocks, and Interceptions.

Conversely, their Attacking based statistics will be decreased, as they will likely be on the ball less frequently than they were at their previous club. This affects metrics like Goals, Assists, Key Passes, and general attacking output.

If a player is from a club with a lower average possession than your club, the effect is reversed. Their Attacking statistics will receive a boost, as they would expect to see more of the ball in your system. Meanwhile, their Defensive statistics are adjusted downwards, reflecting a reduced need to defend due to higher expected team possession.

These adjustments help bring context to raw statistic output, aligning player performance expectations with your tactical environment.

Possession-adjusted statistics are particularly helpful when comparing players across different clubs with contrasting tactical systems. Without adjusting for possession, defenders in low-possession teams often appear to have inflated defensive numbers simply because they are defending more often, not necessarily better.

This method corrects for that imbalance by adjusting a player's output based on how much of the game their team actually has the ball. For example, a player averaging 4 tackles per match in a team with 30% possession is doing so in limited time on the ball, suggesting a higher defensive workload than a player with the same number of tackles in a team with 60% possession.

It is worth noting that possession-adjusted statistics do not account for tactical differences such as pressing intensity, block height, or player role instructions. They simply provide a broader level of context that helps prevent misleading comparisons between players in wildly different systems.

While these adjustments are most meaningful for defensive actions, some attacking metrics, such as passes attempted or progressive passes—can also benefit from possession-based scaling, especially when identifying undervalued players in low-possession teams.

These changes will directly affect how players are ranked and compared throughout the Moneyball tool. This means percentile ranks and derived statistics may shift in response to the new values, offering a more balanced view of each player's potential impact within your system.

You can assign possession values to a maximum of 500 Clubs'. These entries are saved locally in your browser. So if you open the Moneyball tool on a different device or browser, those settings will not carry over.
