Generation

# Expected Goals (xG) **Definition:** xG is a statistical metric that assigns a probability value between 0 and 1 to each shot, representing the likelihood it will result in a goal based on historical data from thousands of similar shots (considering factors like distance, angle, assist type, and defensive pressure). **Why it matters:** xG provides a more accurate measure of team and player performance than raw goals or shots, revealing who is creating genuine scoring opportunities versus getting lucky or wasteful. Over time, xG is more predictive of future results than actual goals scored, making it invaluable for evaluating true team quality and identifying players who are over/underperforming.
