Defense-adjusted Value Over Average (DVOA) is a statistic used in football to measure a player's performance relative to the average player at their position, while also accounting for the strength of the opposing defense. This metric helps to evaluate how well a player performs in different situations, providing a clearer picture of their overall impact on the game. DVOA is particularly useful for comparing players across different teams and seasons, as it adjusts for factors like the quality of the defenses faced. By using DVOA, coaches, analysts, and fans can better understand a player's effectiveness and contribution to their team's success, making it a valuable tool in sports analysis.
