DVOA in Football Explained: The Metric That Measures True Efficiency
Traditional football statistics are notoriously deceptive. A team that gains 400 total yards in a game looks dominant on the stat sheet, but if they achieved those yards through high-volume, low-efficiency plays while trailing by three touchdowns, the number is meaningless. In modern NFL front offices and among sharp sports bettors, the gold standard for evaluating team efficiency is Defense-adjusted Value Over Average (DVOA).
By measuring play-by-play success relative to a situational baseline and adjusting for opponent strength, DVOA isolates true efficiency from schedule strength and random variance. Much like Expected Points Added (EPA) in football or sabermetrics in baseball, DVOA provides the contextual framework needed to find edges in a highly complex sport.
The Foundation of DVOA: Success Points
Developed by pioneer analyst Aaron Schatz and currently hosted by FTN Fantasy, DVOA estimates a team’s efficiency on every play compared to a league-average baseline. The system begins by breaking down the game into individual plays and assigning “success points” based on down and distance.
Unlike traditional stats, DVOA understands that a 5-yard gain is not always created equal:
* A 5-yard gain on 3rd-and-4 is highly successful (resulting in a first down).
* A 5-yard gain on 3rd-and-15 is unsuccessful (resulting in a punt).
* A 5-yard gain on 1st-and-10 is a solid, on-schedule play.
DVOA compares the success of every play to the historical league average in that exact situation—accounting for down, distance, yard line, quarter, score, and time remaining.
$$\text{DVOA} = \frac{\text{Team Performance Value} – \text{League Average Value}}{\text{League Average Value}}$$
The output is expressed as a percentage. A team with a +15% offensive DVOA is 15% more efficient than the league average. Because defense is about preventing efficiency, the scale is flipped for defensive units: a negative defensive DVOA (e.g., -10%) is elite, indicating the defense held opponents to 10% less efficiency than average.
Opponent Adjustments: The “D” in DVOA
The most powerful component of DVOA is the opponent adjustment. A team that averages 6.0 yards per play against the league’s worst defense should not be rated the same as a team that averages 6.0 yards per play against the league’s best defense.
DVOA dynamically adjusts every play based on the defensive strength of the opponent (for offenses) or the offensive strength of the opponent (for defenses).
How the Opponent Adjustment Normalizes Schedule Strength
If Team A plays a schedule dominated by top-5 defenses, their raw, unadjusted efficiency (known as VOA) will be low. Once the opponent adjustment is applied, their DVOA will rise significantly to reward them for facing elite competition.
Conversely, if Team B beats up on bottom-tier defenses, their unadjusted VOA will look elite, but their DVOA will be dragged down to reflect the weak schedule.
| Statistic | unadjusted VOA | opponent adjustment | final DVOA | Analytical Assessment |
|---|---|---|---|---|
| Offense vs. Elite Defense | +5.0% | +12.0% | +17.0% | Excellent performance; heavily upgraded due to opponent strength. |
| Offense vs. Poor Defense | +20.0% | -10.0% | +10.0% | Surface numbers inflated by weak opponent; normalized downward. |
| Defense vs. Elite Offense | +5.0% | -12.0% | -7.0% | Solid defensive effort; adjusted favorably for facing elite offense. |

DVOA vs. DYAR vs. DAVE: Understanding the Suite
To evaluate players and teams holistically, analysts use DVOA alongside two companion metrics: DYAR and DAVE.
1. DYAR (Defense-adjusted Yards Above Replacement)
While DVOA is an efficiency rate metric (like batting average or yards per play), DYAR is a cumulative volume metric (like home runs or total points). It measures how many total yards a player gained relative to a “replacement-level” baseline player.
This is crucial because a backup running back might have a +25% DVOA on 15 carries, but a workhorse running back with a +5% DVOA on 250 carries adds significantly more total value (DYAR) to the offense over the course of a season.
2. DAVE (DVOA Adjusted for Variegated Early-season projection)
In the first few weeks of an NFL season, statistical samples are small and noisy. If a team plays one terrible game in Week 1, their raw DVOA will look catastrophic.
To fix this, the DAVE metric blends the team’s current in-season DVOA with their preseason projection. As the season progresses, the weight of the preseason projection decreases:
* Week 1: DAVE is weighted heavily toward the preseason projection.
* Week 4: The blend shifts to roughly 50% in-season data and 50% preseason projection.
* Week 8: Preseason projections are completely phased out, and DAVE becomes identical to DVOA.

How to Use DVOA for NFL Sports Betting
For sports bettors, DVOA is the primary tool for identifying market inefficiencies, particularly in point-spread and futures markets.
1. Spotting the “Fake” Records
Traditional NFL standings list teams by their win-loss records. However, a team can go 10-3 due to recovering an unsustainable number of opponent fumbles, winning close one-score games, or playing a weak schedule.
If a 10-3 team has a DVOA of +2.0% (ranking 15th in the league), they are prime regression candidates. When they face a 7-6 team with a DVOA of +12.0% (ranking 6th), the sportsbooks will often favor the 10-3 team, creating high-value point-spread betting opportunities on the lower-ranked team.
2. The Power of Pass DVOA over Run DVOA
When building a betting model, weight Pass DVOA significantly higher than Run DVOA. Pass DVOA is highly correlated with winning games and has a stronger predictive value.
If a team has a top-5 Pass DVOA but a bottom-5 Run DVOA, they are still an elite offense. If a team has a top-5 Run DVOA but a bottom-5 Pass DVOA, their offense is highly volatile and unlikely to sustain success against elite pass rushes.
3. Net DVOA for Spread Valuation
Calculate the “Net DVOA” of a matchup by subtracting the defensive DVOA from the offensive DVOA of each team. Compare the Net DVOA difference to the sportsbook’s point spread.
Much like Strokes Gained in golf, a significant divergence between a team’s Net DVOA and the market line indicates that the market is overreacting to surface-level trends rather than pricing the underlying efficiency.
Frequently Asked Questions
What is a good DVOA percentage?
A DVOA of 0% represents the league average. For offenses, +10% is good, and +20% or higher is elite. For defenses, a negative percentage is desired: -10% is good, and -20% or lower is elite.
Who owns the DVOA metric now?
DVOA was originally developed by Aaron Schatz at Football Outsiders. As of July 2026, the metric is owned, calculated, and hosted by FTN Fantasy.
How does DVOA handle garbage time?
DVOA filters out plays that occur when a game is essentially decided (e.g., a team leading by 28 points in the fourth quarter) to prevent useless yardage from inflating or deflating a team’s true efficiency ratings.
