What DVOA Measures

DVOA (Defense-adjusted Value Over Average) is a sophisticated statistical metric that evaluates football performance by comparing a team's actual results to what would be expected based on the league average, while accounting for the strength of opponents faced. Created by Aaron Schatz and Football Outsiders, DVOA has become one of the most respected advanced statistics in football analysis.

How DVOA Works

The calculation adjusts traditional statistics by weighting plays based on down and distance situations. For example, a first-down conversion is weighted differently than a successful third-down conversion. The metric also accounts for opponent quality, so beating a strong defense counts more than beating a weak one. Each team's performance is compared to the league average performance in equivalent situations to produce the final DVOA rating.

DVOA Categories

• Offensive DVOA measures how well an offense performs relative to the league average
• Defensive DVOA evaluates how effectively a defense performs against opponents
• Special Teams DVOA assesses kicking, punting, and return team performance

Interpretation and Applications

DVOA values typically range from approximately -50 to +50, with 0 representing league-average performance. A team with an offensive DVOA of +10 is performing 10 points better per game than the league average when adjusted for opponent strength. High DVOA ratings have proven predictive of future success and playoff performance, making the metric valuable for season projections and team evaluations. Coaches, analysts, and sports bettors use DVOA extensively for strategic planning and performance assessment.
