Expected Effective Field Goal Percentage (XeFG%) is defined as the percentage of shots a league average player would successfully make depending on the type of shots a player attempts.
For example, centers tend to have higher XeFG% values than guards because they shoot inside of the paint more often, where the league average percentage is obviously higher.
Therefore, a player’s actual Effective Field Goal Percentage (eFG%) can be compared to their XeFG% to determine if they’re performing above (positive +/-) or below (negative +/-) expectation.
