Mathematical & Tactical Standards

Target Share

TGT%Volume & Opportunity

The percentage of a team's total pass attempts directed toward a specific receiver or tight end.

Calculation Formula:(Player Targets / Team Total Pass Attempts) × 100
Why It Matters for Fantasy

Target volume is the single most predictive metric for fantasy wide receivers and tight ends. Targets are earned by winning routes, making target share far more stable week-to-week than touchdown output or raw receiving yards.

Tactical Start/Sit Tip

Target players commanding a >25% target share regardless of matchup, and treat receivers under 15% target share as highly volatile flex plays.

Benchmark Standards & Tiers
Tier 1: Alpha Elite> 25.0%

Every-week WR1 anchor (e.g. Justin Jefferson, Ja'Marr Chase)

Tier 2: Strong Starter18.0% – 24.9%

Reliable weekly WR2/WR3 or top-tier TE1

Tier 3: Flex Rotation12.0% – 17.9%

Matchup-dependent WR3/Flex asset

Tier 4: Volatile Sub< 12.0%

Touchdown-dependent rotational player

2026 Reference Starter:Justin Jefferson(31.5% Target Share Floor)

Snap Count Share

SNAP%Volume & Opportunity

The percentage of total offensive plays that a player is physically on the field.

Calculation Formula:(Player Offensive Snaps / Total Team Offensive Snaps) × 100
Why It Matters for Fantasy

A player cannot score fantasy points from the sideline. Snap share establishes the baseline opportunity ceiling for running backs, wide receivers, and tight ends.

Tactical Start/Sit Tip

A running back playing under 50% of snaps requires hyper-efficient touchdown variance to sustain RB1 value, whereas an 80%+ snap back provides elite floor security.

Benchmark Standards & Tiers
Every-Down Bellcow> 75.0%

League-winning volume security (e.g. Bijan Robinson, Saquon Barkley)

Primary Starter60.0% – 74.9%

Strong starter with minor third-down breather rotation

Committee / 1B45.0% – 59.9%

Shared backfield split requiring high efficiency

Rotational Reserve< 45.0%

Contingency handcuff or specialized third-down back

2026 Reference Starter:Bijan Robinson(84.5% Snap Dominance)
View Bijan Robinson's Live Gauges

Route Participation Rate

RPR%Volume & Opportunity

The percentage of team pass dropbacks on which a receiver or tight end runs a pass route.

Calculation Formula:(Player Routes Run / Team Total Pass Dropbacks) × 100
Why It Matters for Fantasy

Snap share can be misleading for tight ends who stay in to pass-block or run-block. Route participation measures true opportunity to earn targets on passing plays.

Tactical Start/Sit Tip

Only draft and start tight ends with an 80%+ route participation rate; blocking tight ends with low route participation have virtually zero fantasy ceiling.

Benchmark Standards & Tiers
Elite Alpha Route Share> 85.0%

Full-time route runner on virtually all pass plays

Solid Starter75.0% – 84.9%

Standard WR2 or pass-catching TE1

Rotational / 2-TE Set55.0% – 74.9%

Rotational pass catcher with capped volume

Blocking Specialist< 55.0%

Primarily used for pass protection or run blocking

2026 Reference Starter:Brock Bowers(88.0% Route Participation)

Air Yards & Air Yards Share

AY%Volume & Opportunity

The total distance a football travels through the air past the line of scrimmage to a receiver, and the share of team total air yards.

Calculation Formula:(Player Total Air Yards / Team Total Air Yards) × 100
Why It Matters for Fantasy

Air yards reflect coaching intent and quarterback aggression. High air yards combined with low current receptions often signal an imminent positive regression breakout.

Tactical Start/Sit Tip

Buy low on wide receivers with high air yards share (>35%) who suffered from poor catchable pass rates in recent games.

Benchmark Standards & Tiers
Deep Alpha Monster> 38.0%

Commanding deep downfield tree (e.g. CeeDee Lamb, Malik Nabers)

Primary Target28.0% – 37.9%

Standard downfield starter

Possession Receiver18.0% – 27.9%

Weighted Opportunity Rating

WOPRVolume & Opportunity

A composite metric developed to combine target share and air yards share into a single comprehensive opportunity metric.

Calculation Formula:1.5 × (Target Share) + 0.7 × (Air Yards Share)
Why It Matters for Fantasy

WOPR is widely recognized as the single strongest leading indicator of future fantasy wide receiver point output, balancing short-yardage target volume with deep downfield equity.

Tactical Start/Sit Tip

A WOPR above 0.60 indicates a true top-10 fantasy wide receiver with matchup-proof workload security.

Benchmark Standards & Tiers
Top-Tier Alpha> 0.65

High-Value Touches

HVTVolume & Opportunity

The sum of a running back's pass receptions and goal-line/red-zone carries.

Calculation Formula:Total Receptions + Carries inside Opponent 20-Yard Line
Why It Matters for Fantasy

In modern PPR formats, receptions and red-zone carries are worth approximately 2.8x more fantasy points than standard early-down carries between the 20-yard lines.

Tactical Start/Sit Tip

Prioritize running backs who monopolize high-value touches even if their total carry count is lower than pure two-down rushers.

Benchmark Standards & Tiers
Elite HVT Bellcow> 8.5 HVT / Game

League-winning RB1 profile (e.g. Christian McCaffrey, Jahmyr Gibbs)

Strong Starter5.5 – 8.4 HVT / Game

Solid RB1/RB2 with pass-game involvement

Red Zone Opportunity Share

RZ%Risk & Valuation

The percentage of a team's total plays inside the opponent 20-yard line that result in a carry or target for the player.

Calculation Formula:(Player RZ Carries + RZ Targets / Team Total RZ Plays) × 100
Why It Matters for Fantasy

Touchdowns account for roughly 30% to 40% of top-tier fantasy scoring. Players who command the majority of their team's red-zone touches possess the highest weekly scoring ceilings.

Tactical Start/Sit Tip

A running back with >35% red-zone share has multiple touchdown equity in every high-scoring game environment.

Benchmark Standards & Tiers
Goal-Line Dominator> 35.0%

Primary scoring weapon with multi-TD ceiling

Primary Red Zone Option25.0% – 34.9%

Expected Fantasy Points

xFPEfficiency & Advanced

The quantity of fantasy points a league-average player would score given the exact down, distance, yard line, and type of every touch.

Calculation Formula:Σ (Historical League-Average Points per Play Context)
Why It Matters for Fantasy

xFP removes touchdown luck and random big plays to reveal the underlying structural value of a player's role in their offense.

Tactical Start/Sit Tip

Players whose actual fantasy scoring is significantly lower than their xFP are prime buy-low trade candidates poised for positive regression.

Benchmark Standards & Tiers
Elite Overall Role> 18.0 xFP / Game

Fantasy Points Over Expected

FPOEEfficiency & Advanced

The difference between a player's actual fantasy points scored and their expected fantasy points based on touch volume context.

Calculation Formula:Actual Fantasy Points − Expected Fantasy Points (xFP)
Why It Matters for Fantasy

FPOE highlights individual playmaking efficiency, tackle-breaking, and contested catch skill above league averages.

Tactical Start/Sit Tip

Extreme positive FPOE (>+6.0/G) with low underlying xFP is rarely sustainable year-over-year and indicates a prime sell-high candidate.

Benchmark Standards & Tiers
Hyper-Efficient Playmaker> +4.0 FPOE / G

Elite explosive finisher (e.g. Lamar Jackson, De'Von Achane)

Above Average Finisher+1.0 to +3.9 FPOE / G

Yards Per Route Run

YPRREfficiency & Advanced

Total receiving yards divided by total routes run on passing plays.

Calculation Formula:Total Receiving Yards / Total Routes Run
Why It Matters for Fantasy

YPRR is the premier rate metric for receiver efficiency, eliminating team passing volume biases to isolate per-route playmaking prowess.

Tactical Start/Sit Tip

A receiver with >2.20 YPRR who sees an increase in team route participation will almost always explode into an elite fantasy producer.

Benchmark Standards & Tiers
Elite Alpha Tier> 2.40 YPRR

Elite superstar WR1 tier (e.g. Tyreek Hill, Justin Jefferson)

Strong Starter1.80 – 2.39 YPRR

High-quality WR2 or elite TE1

Average Starter1.30 – 1.79 YPRR

Average Depth of Target

aDOTEfficiency & Advanced

The average distance (in yards downfield) from the line of scrimmage at which a player is targeted.

Calculation Formula:Total Air Yards / Total Targets
Why It Matters for Fantasy

aDOT categorizes player role: low aDOT receivers rely on high reception volume and YAC, while high aDOT receivers provide explosive ceiling but higher volatility.

Tactical Start/Sit Tip

Pair high-aDOT deep threats with low-aDOT slot receivers to construct a balanced, high-floor roster.

Benchmark Standards & Tiers
Deep Field Stretcher> 13.0 yards

Boom/bust vertical threat (e.g. Jameson Williams)

Complete Intermediate10.0 – 12.9 yards

Expected Points Added

EPA / PlayEfficiency & Advanced

The net change in expected team points produced by a player on each individual play compared to NFL historical baselines.

Calculation Formula:Net Expected Points at Play End − Expected Points at Play Start
Why It Matters for Fantasy

EPA/play measures real-world football impact. Quarterbacks and offenses with high EPA sustain drives, generate more red-zone trips, and score more total touchdowns.

Tactical Start/Sit Tip

Stack quarterbacks and pass catchers from top-5 EPA offenses to benefit from elevated team scoring efficiency.

Benchmark Standards & Tiers
Elite MVP Caliber> +0.22 EPA / Play

Target Separation

SEPEfficiency & Advanced

The distance in yards between a receiver and the closest defender at the exact moment the pass arrives or is caught.

Calculation Formula:Distance (in yards) to nearest defender at catch point (Next Gen Stats)
Why It Matters for Fantasy

Separation measures route-running crispness and agility against man and zone coverage. Receivers who create wide separation earn easier targets and higher completion rates.

Tactical Start/Sit Tip

Wide receivers with >3.2 yards of separation consistently outperform contested-catch specialists in weekly scoring stability.

Benchmark Standards & Tiers
Elite Route Technician> 3.5 yards

Yards After Contact Per Attempt

YAC/AttEfficiency & Advanced

The number of rushing yards a ballcarrier gains after the first physical contact by an opposing defender.

Calculation Formula:Rushing Yards Gained After First Defender Contact / Total Carries
Why It Matters for Fantasy

YAC/Att isolates individual running back talent and tackle-breaking ability from offensive line run-blocking quality.

Tactical Start/Sit Tip

Target running backs with >3.3 YAC/Att who play behind improving offensive lines for massive second-half breakout potential.

Benchmark Standards & Tiers
Elite Tackle-Breaker> 3.4 YAC / Att

Pylon Circular Rating

PRRisk & Valuation

Pylon's proprietary 0–99 composite index evaluating a player's weekly ceiling, workload dominance, situational leverage, and scoring consistency.

Calculation Formula:Composite Weighted Algorithm (Target/Touch Volume + Red Zone Equity + Route Participation + Downside Stability)
Why It Matters for Fantasy

Rather than looking at confusing spreadsheets, the Pylon Circular Rating simplifies complex underlying metrics into an intuitive 0–99 gauge for instant start/sit and trade decisions.

Tactical Start/Sit Tip

Always start players with a 90+ Pylon Rating, and use ratings comparisons to resolve start/sit debates between similar-tier flex assets.

Benchmark Standards & Tiers
Tier 1: Supermax Anchor94 – 99

Matchup-proof superstar (e.g. Josh Allen, Saquon Barkley, Justin Jefferson)

Tier 2: Elite Starter89 – 93

Downside Bust Risk Index

BRI%Risk & Valuation

The modeled probability that a starting fantasy player scores fewer than 50% of their projected point baseline in a given week.

Calculation Formula:Downside Variance Model (Touch Floor Stability + Backfield Rotation + Red Zone Touch Concentration)
Why It Matters for Fantasy

Winning championships requires minimizing zero-floor duds in starting lineups. Bust Risk identifies trap plays with high projected points but dangerous touch volatility.

Tactical Start/Sit Tip

In close matchups, bench high bust-risk starters (>25%) in favor of steady high-floor volume plays (<15% risk).

Benchmark Standards & Tiers
Very Low Risk (Iron Floor)< 14.0%

Virtually zero dud risk (e.g. Josh Allen, Saquon Barkley)

Low Risk (Stable)14.0% – 19.9%
