NFL analyzer explained
To analyze an NFL player prop, start with the current listed line and verify that a slate is available. Then review expected role and volume, position matchup, injuries, game environment, recent form, and market movement. Propeller combines only the available NFL signals and shows which More/Over or Less/Under direction they support.
Available inputs can include expected role and volume, position matchup, injury cascades, game environment, recent form, line movement, and market context. Missing or neutral signals are skipped.
A 50-100 directional model-confidence score shows how strongly the available signals support the displayed More/Over or Less/Under direction. It is not a calibrated win probability or guarantee.
NFL roles and lines can change with practice reports, injuries, weather, and inactive lists. Confirm the player, stat, line, and timestamp before using any analysis.
Availability noteDuring the offseason, preseason ramp, or days without a current NFL slate, no current props may be available. This page should show an empty state rather than relabeling older analysis as today.

Football Is Not Like Other Sports
Defense-adjusted value over average is not uniform across an opposing roster. A defense that suppresses wide receivers may be exploitable at running back. Propeller's Matchup agent evaluates DVOA at the position level, matching each player's role against the specific defensive unit responsible for covering that position group. It is the highest-weighted signal in the NFL model.
Propeller records available timestamped odds snapshots and treats directional changes as context to investigate alongside role, injury, and lineup news. A changing line does not reveal why the market moved or establish that either side is favorable, so it is never presented as a standalone signal.
NFL injury reports are released throughout the week on a Wednesday-Thursday-Friday-Saturday cadence. A receiver's practice participation on Wednesday can shift their prop by midweek, and full-game exclusions on Sunday morning can render a prop unplayable entirely. Propeller tracks OUT and IR designations, eliminates props for sidelined players, and redistributes expected target share and carry volume to teammates who benefit.
Sportsbook prices include a margin. Propeller can remove that margin from both sides of a listed market to estimate the implied probability represented by those prices. Cross-book disagreement is recorded as additional context, not proof that either side is favorable.
The Engine
The highest-weighted signal in Propeller NFL analysis. This agent evaluates position-specific defensive DVOA: not how a defense performs overall, but how it performs specifically against the position group the target player occupies. A wide receiver who lines up in the slot faces a fundamentally different defensive assignment than a receiver who lines up outside. A run-blocking defense that excels against outside runs may surrender interior carries at a higher rate. The Matchup agent maps each player's primary role, identifies the specific defensive unit they will face in the game, and produces a directional confidence score based on historical DVOA differential against comparable players in the same role.
Defense-adjusted value over average measures how efficiently a team performs relative to a league-average baseline, adjusted for opponent quality. The DVOA agent calculates z-scores for both team offensive DVOA and opponent defensive DVOA, generating a composite efficiency signal that reflects whether the game environment favors volume and production at the team level. A team with a high offensive DVOA facing a defense with a low defensive DVOA creates a favorable environment for every player on that roster.
Timestamped odds snapshots show how listed prop lines change over time. The LineMovement agent records that movement alongside other available context; a line move can reflect many factors and does not prove an outcome or an unavailable market adjustment.
A player listed as OUT or on IR has their own props eliminated from consideration immediately. But the Injury agent goes further: it models cascading teammate effects, identifying which players in the same rotation stand to absorb the missing player's target share, snap count, or carry volume. A number-one receiver ruled out on a Saturday morning can transform the number-two receiver's receiving yards prop from a neutral signal to a high-confidence opportunity before the book adjusts its line.
Bilateral no-vig analysis removes the sportsbook margin from both sides of a listed prop line to estimate an implied probability. Price differences and juice direction are retained as market context, while the displayed directional score remains a research signal rather than proof of an advantage.
Database-powered historical trend analysis from the NFL player stats table — a full replacement for simple hit-rate calculations. This agent surfaces recency-weighted performance patterns across the current season, weighting the last four games more heavily than earlier results to reflect current role, offensive system fit, and usage trajectory.
Player quality z-scores derived from three Next Gen Stats signals: CPOE (completion percentage over expectation for quarterbacks), separation distance at the catch point for receivers, and RYOE (rushing yards over expectation) for running backs. These metrics isolate individual player quality from the noise of overall team performance.
Raw usage volume tracking: target share percentage, snap participation rate, and carry volume trend for skill position players. Even when quality metrics are mixed, a player who consistently earns 30% of their team's targets in a high-volume offense occupies a favorable structural position relative to their prop line.
Available analysis signals are combined with sport-specific weights. Signals without a usable result are skipped, and sport-specific adjustments are applied before the displayed directional score is published.
What We Score
The highest-volume quarterback prop. Driven by game script, opponent pass DVOA, pace of play, and projected total. Blowout risk suppresses passing volume significantly.
Correlated with target share, air yards allocation, and the pass-heaviness of the game script. Matchup DVOA against the receiver's alignment — inside vs. outside — is the critical signal.
Strongly linked to carry volume, opponent run DVOA, and whether the game script projects as run-favorable. RYOE z-scores identify backs who consistently beat their expected output.
Target share and route participation rate are the primary predictors. Slot receivers with high target floors in short-area passing attacks carry the most consistent reception props.
Correlated with red zone efficiency, opponent red zone pass DVOA, and projected game total. Higher-total games generate more scoring opportunities for both teams.
Red zone target share and goal-line carry percentage are key. Injury cascades frequently create the strongest anytime TD edges when a primary scorer is ruled out and their red zone role redistributes.
Tied closely to game script — pass-heavy games driven by deficit or high totals generate more attempts and completions. CPOE z-score isolates quarterback accuracy quality from opportunity.
Snap rate, backfield role, and game script projection determine expected carry volume. Home favorites with a strong run game and a projected positive game script see the highest carry ceilings.

Editorial review
Reviewed by Scott Olmer. The page distinguishes a verified current slate from the historical archive and avoids presenting confidence as a win probability.
Current slate state comes from the public NFL slate endpoint. Read the method, version record, and historical archive definitions before quoting results.

AI player-prop research
These pages request current public preview data. When a slate is empty or unavailable, the page should show that state instead of relabeling an older row as today. Confidence is directional model conviction, not win probability.
