Win shares

Win Shares is a statistical metric used to evaluate a player’s contribution to their team's success in sports, particularly in baseball and basketball. It quantifies how many wins a player is responsible for, based on their performance—taking into account offensive and defensive contributions. Essentially, it breaks down how a player's actions on the field or court translate into actual victories for their team. By aggregating these figures across a season or career, analysts can compare players’ impacts on winning, providing a clearer picture of their overall effectiveness and value.
