Stats Glossary
A quick reference for the advanced metrics highlighted throughout our Saints analytics dashboards.
Read methodology notes- Expected Points Added (EPA)
- EPA measures the value of a play by comparing the expected points before and after the snap. Positive EPA means the play increased the team's scoring outlook, while negative EPA means the opposite.Related: EPA/play, Total EPA
- Success Rate
- Success rate is the percentage of plays that increase the offense's expected points. It is a consistency metric that complements EPA by valuing sustained drives over explosive but rare gains.
- Completion Percentage Over Expected (CPOE)
- CPOE compares a quarterback's actual completion rate to an expected rate based on throw depth, location, and game situation. Positive numbers indicate a passer is hitting throws that most players miss.
- Air Yards
- Air yards track how far the football travels past the line of scrimmage on a pass attempt. They help separate the quarterback's aggressiveness from yards gained after the catch.
- Yards After Catch (YAC)
- YAC represents the yards a receiver gains after securing the football. It highlights playmaking ability once the ball is in a player's hands.
- Pressure Rate
- Pressure rate is the share of pass plays where the defense hurries, hits, or sacks the quarterback. It is a quick way to spot which linemen are winning at the snap.
- Average Depth of Target (aDOT)
- aDOT captures how far downfield, on average, a receiver is targeted. Bigger numbers mean routes are developing deeper before the ball arrives, while smaller values reflect underneath usage.
- Yards Per Route Run (YPRR)
- YPRR divides a receiver's total receiving yards by the number of routes they run, blending efficiency and volume to highlight who creates production on a per-route basis.
- Win Probability
- Win probability models estimate the Saints' chance to win at each moment using score, clock, field position, and other factors. Swings in win probability illustrate the game's biggest inflection points.
- Playoff Odds / Projected Wins
- Playoff odds and projected wins are model snapshot outputs. On Who Dat Stats, archived odds are labeled as historical and should not be treated as a current forecast unless the page explicitly says current-season data is active.Related: Win Probability, Season Outlook
- Matchup Advantage
- Matchup advantage summarizes where the Saints may have an edge once verified Saints and opponent inputs are available. If opponent data is missing, the site shows a pending state rather than fabricating an edge.Related: EPA/play, Success Rate, Pressure Rate
- Player Trend Metrics
- Player trend metrics compare recent available game logs with the earlier sample for that player. Missing position-specific fields are omitted and small samples are labeled as insufficient data.Related: EPA/play, Success Rate, CPOE, Pressure Rate
- Model-Generated Reports
- Automated reports are displayed only when report rows exist. Pending report cards describe planned report types and should not be read as completed analysis.
- Fourth Down Model
- The fourth down model weighs go-for-it, punt, and field goal options using expected points and win probability to recommend the choice that maximizes long-term success.
