Briefly explain shot quality metrics and one common misconception about it.

# Shot Quality Metrics **Shot quality metrics** (like Expected Goals or xG) estimate the probability that a shot will result in a goal based on historical data. They consider factors such as: - Distance from goal - Angle to goal - Type of assist (pass, cross, rebound) - Body part used - Defensive pressure These metrics help evaluate team and player performance independent of finishing skill or luck. ## Common Misconception **"A player consistently outperforming their xG means the metric is wrong."** This misunderstands what xG measures. Expected goals represents the *average* shooter's probability of scoring from similar positions. Elite finishers *should* outperform xG regularly—that's what makes them elite. The metric isn't "wrong"; it's the baseline that helps us identify who has genuinely exceptional finishing ability versus who's been lucky. The real value is in identifying trends: a team creating high xG will likely score more eventually, while one scoring well above xG may regress to the mean.
