Advanced quarterback analytics measure player performance using metrics like EPA/play, CPOE, sack rate, and deep-ball accuracy-going far beyond passing yards and passer rating to reveal true decision-making, pocket poise, and play-driving value.
These advanced quarterback analytics combine NFL Next Gen Stats tracking data, film-based grading, and probabilistic models to quantify what traditional stats miss. For example, expected points added (EPA) per play captures how much value a QB adds on every snap, while completion percentage over expectation (CPOE) isolates accuracy from receiver contributions.
Core Advanced Quarterback Metrics Explained
Modern quarterback evaluation relies on three pillars: efficiency metrics, pressure-adjusted stats, and contextual value measures. Together they form a comprehensive performance evaluation framework that front offices and fantasy analysts use daily.
- EPA/play (Expected Points Added): Measures how many points a QB adds per play relative to down, distance, and field position; league average is 0.0, elite QBs exceed +0.25.
- CPOE (Completion Percentage Over Expectation): Compares actual completions to an AI model's predicted completion rate based on throw distance, coverage, and defender proximity; positive values indicate superior accuracy.
- Sack Rate: Percentage of dropbacks ending in a sack, adjusted for offensive line quality; elite QBs stay under 5.5%.
- Deep Ball Accuracy: Completion percentage and EPA on throws traveling 20+ air yards; critical for stretching defenses.
- Pocket Time: Average milliseconds before pressure arrives; top QBs average 2.7+ seconds.
- Scramble %: Frequency of designed or improvisational runs; correlates with extending drives.
2025 NFL Quarterback Advanced Stats Leaderboard
The 2025 season revealed stark differences when applying advanced quarterback analytics versus traditional box scores. Jordan Love led the league in passer rating (103.8), but EPA/play and CPOE told a richer story about true efficiency.
| Rank | Quarterback | Team | EPA/Play | CPOE (%) | Sack Rate (%) | Deep Ball % | Pocket Time (s) |
|---|---|---|---|---|---|---|---|
| 1 | Jordan Love | GB | +0.31 | +6.8 | 4.9 | 48.2 | 2.81 |
| 2 | Josh Allen | BUF | +0.29 | +5.4 | 5.2 | 45.7 | 2.74 |
| 3 | Sam Darnold | SEA | +0.27 | +7.1 | 5.0 | 44.3 | 2.69 |
| 4 | Matthew Stafford | LAR | +0.24 | +4.9 | 5.8 | 46.1 | 2.77 |
| 5 | Bo Nix | DEN | +0.21 | +3.7 | 5.4 | 42.8 | 2.63 |
| 6 | Drake Maye | NE | +0.19 | +4.2 | 6.1 | 41.5 | 2.58 |
| 7 | Caleb Williams | CHI | +0.17 | +2.9 | 6.4 | 39.7 | 2.51 |
| 8 | Patrick Mahomes | KC | +0.26 | +5.8 | 5.3 | 47.4 | 2.79 |
This efficiency leaderboard shows why insiders prioritize EPA/play over passer rating: Love's +0.31 EPA/play in 2025 translated to 12 more expected wins than a league-average QB, while traditional stats alone would understate his impact.
Why Insiders Guard These Metrics
Front offices treat advanced quarterback analytics as proprietary competitive advantages. Teams using proprietary models like PFF's graded pressure data or ESPN's QBR gain edge in drafts, trades, and contract negotiations.
- Proprietary Data Sources: NFL Next Gen Stats uses RFID chips in shoulder pads to track positioning at 10Hz, creating exclusive datasets not publicly available in real-time.
- Model Transparency Risk: Revealing exact weightings (e.g., how much deep EPA outweighs red-zone EPA) lets opponents exploit scouting weaknesses.
- Contract Leverage: QBs with high CPOE but low passing yards can demand more once teams understand their true efficiency.
- Draft Strategy: Teams like the 49ers and Chiefs use internal EPA projections to target undervalued college QBs before scouts notice.
- Media Narrative Control: Publicizing only traditional stats protects veteran QBs from efficiency-based criticism during slumps.
"The teams winning superbowls since 2020 all rank top-5 in EPA/play and CPOE. Traditional stats are lagging indicators; advanced metrics predict future performance 63% better over 16-game samples."
- Former NFL VP of Football Analytics, quoted October 22, 2024
How to Calculate EPA and CPOE Yourself
Understanding the mathematical foundation behind these metrics empowers fans and analysts to build their own evaluation models. Here's the step-by-step process used by professional analysts.
- For EPA/play: Start with the expected points (EP) before the snap (based on down, distance, field position). Subtract EP after the play. The difference is EPA. Divide by total dropbacks for EPA/play.
- For CPOE: Run a logistic regression model using throw distance, coverage type (man/zone), pressure status, and defender proximity. Model outputs expected completion %. Subtract from actual completion %.
- For Sack Rate: Count sacks divided by total dropbacks (pass attempts + sacks + QB rushes). Adjust for offensive line pressure metrics from Next Gen Stats.
- For Pocket Time: Use Next Gen Stats pressure arrival timestamp minus dropback timestamp. Average across all dropbacks.
- For Deep Ball Accuracy: Filter passes with 20+ air yards. Calculate completion % and EPA separately. Elite QBs exceed 45% completion and +0.40 EPA on deep throws.
This analytical workflow mirrors what NFL teams run internally, minus proprietary weighting adjustments that account for weather, injuries, and game script.
Historical Context: Evolution of QB Analytics
Quarterback evaluation has undergone three distinct phases since 2000. The traditional era (2000-2010) relied on passer rating and TD-INT ratio. The efficiency revolution (2011-2018) introduced QBR and adjusted YPA. The tracking era (2019-present) brought EPA, CPOE, and Next Gen Stats.
In 2015, passer rating crowned Peyton Manning as MVP despite his 3,491 yards and 22 TDs-below league-adjusted averages. By 2025, EPA/play revealed Patrick Mahomes as the true elite performer despite similar traditional stats, demonstrating metric evolution impact.
Practical Applications for Fans and Analysts
Applying advanced quarterback analytics transforms how you watch games, evaluate drafts, and build fantasy teams. Fans can now identify undervalued QBs like Sam Darnold in 2025, whose +7.1 CPOE signaled elite accuracy despite modest yardage.
Front offices use these metrics to structure contracts: QBs with high EPA/play but low yards receive back-loaded deals, while those with poor sack rates get incentive-laden extensions. This data-driven negotiation approach saved teams $47M in overpaid contracts in 2024 alone.
For fantasy managers, tracking weekly EPA trends helps identify breakout QBs before yards accumulate. In Week 8 of 2025, Drake Maye's +0.34 EPA/play forecast his 342-yard, 4-TD explosion two weeks before traditional stats caught up.
The future of quarterback evaluation lies in machine learning models that combine tracking data, film analysis, and biometric sensors to predict injury risk and performance decay. Teams already prototype these systems for 2026 drafts.
By mastering advanced quarterback analytics, you gain the same analytical edge as NFL insiders-revealing true performance hidden beneath traditional box scores and media narratives.
Expert answers to Why Advanced Quarterback Analytics Fool Most Fans queries
What are advanced quarterback analytics?
Advanced quarterback analytics are metrics like EPA/play, CPOE, sack rate, and deep-ball accuracy that measure QB performance beyond traditional stats, using tracking data and probabilistic models to isolate individual contribution.
Why do insiders not share advanced QB stats?
Teams guard proprietary quarterback metrics as competitive advantages for drafts, trades, and contracts; revealing exact model weightings would let opponents exploit scouting weaknesses.
Which metric best predicts QB success?
EPA/play is the strongest predictor, correlating 63% with future wins over 16-game samples; CPOE ranks second at 58%, while passer rating drops to 34%.
What is a good EPA/play for a QB?

How is CPOE different from completion percentage?
CPOE subtracts the AI-predicted completion rate (based on throw distance, coverage, pressure) from actual completion %, isolating QB accuracy from receiver quality and play design.
Do advanced stats matter for fantasy football?
Yes-EPA/play and sack rate predict fantasy scoring consistency better than passing yards; QBs with +0.25 EPA/play average 18.4 FP/game versus 14.2 for league-average QBs.
