ADP

Drafting

Average Draft Position. The average pick number at which a player is selected across multiple drafts. Used to gauge market value and identify value picks.

Related:VBDVORP

Boom/Bust

Risk

A player who has high variance in weekly scoring. Boom weeks produce elite numbers while bust weeks are well below expectations.

Related:VolatilityConsistency Score

Bye Week

General

The week during the NFL season when a team does not play. Fantasy managers must plan roster depth around bye weeks to avoid starting empty slots.

Related:Roster Management

Ceiling

Projections

The maximum realistic fantasy point output a player could achieve in a given week or season. High-ceiling players have explosive upside potential.

Related:FloorRange of Outcomes

Consistency Score

Analytics

A metric (0-100) measuring how reliably a player produces fantasy points week to week. Higher scores indicate less variance and more predictable output.

Related:VolatilitySharpe Ratio

Dynasty League

League Types

A fantasy football league format where managers keep their entire roster from year to year, with rookie drafts each season. Emphasizes long-term team building.

Ensemble Projection

Analytics

A forecasting method that combines multiple models (EWMA, RTM, 3-year average, SOS) with optimized weights to produce a single, more accurate projection.

Related:EWMARTMSOS

EWMA

Analytics

Exponentially Weighted Moving Average. A statistical method that gives more weight to recent data points. Used in the Ronin projection engine to capture trending performance.

Related:RTMEnsemble Projection

FAAB

Waivers

Free Agent Acquisition Budget. A dollar amount allocated to each team for bidding on free agents throughout the season. Replaces traditional waiver priority systems.

Flex

General

A roster position that can be filled by a RB, WR, or TE (and sometimes QB in SuperFlex leagues). Provides lineup flexibility.

Floor

Projections

The minimum realistic fantasy point output a player is expected to produce. High-floor players provide safe, consistent production.

Related:CeilingRange of Outcomes

Game Script

Analytics

The flow and situation of a game that affects player usage. Teams trailing tend to pass more, while teams leading tend to run more.

Related:GSI

GSI

Analytics

Game Script Impact. A metric measuring how a player's fantasy production is affected by game flow (leading vs. trailing). Positive GSI means the player benefits from positive game scripts.

Half-PPR

Scoring

A scoring format where players receive 0.5 points per reception, in addition to yardage and touchdown points. A middle ground between Standard and full PPR.

Handcuff

Strategy

A backup running back who would assume the starting role if the starter is injured. Often drafted by the same manager who owns the starter as insurance.

IDP

League Types

Individual Defensive Player. A league format where managers draft individual defensive players (DL, LB, DB) instead of team defenses.

IRV

Analytics

Injury Risk Volatility. A multiplier applied to projections based on a player's injury history and current health status. Higher IRV reduces projected output.

Related:Risk Analysis

Keeper League

League Types

A league format where each manager can retain a limited number of players from their previous season's roster, typically at a draft cost.

Positional Scarcity

Strategy

The concept that positions with fewer elite options (like TE) are more valuable to draft early because replacement-level production drops off significantly.

Related:VBDVORP

PPR

Scoring

Points Per Reception. A scoring format where players receive 1 full point for each catch, in addition to yardage and touchdown points. Increases value of pass-catching players.

R-Squared (R²)

Analytics

A statistical measure (0-1) indicating how well a model's predictions match actual results. Higher R² means better predictive accuracy.

Range of Outcomes

Projections

The spread between a player's floor and ceiling projections. Wider ranges indicate more uncertainty and risk.

Related:FloorCeiling

Redraft League

League Types

A standard fantasy football league where all players are returned to the pool at the end of each season and a new draft is held.

Regression to Mean (RTM)

Analytics

The statistical tendency for extreme performances to move toward the average over time. Players with outlier seasons are expected to regress.

Related:EWMAEnsemble Projection

Roster Management

General

The ongoing process of managing your fantasy team's lineup, including start/sit decisions, waiver wire pickups, and trade negotiations.

Sharpe Ratio

Analytics

A risk-adjusted performance metric borrowed from finance. In fantasy, it measures points scored relative to scoring volatility. Higher is better.

Related:VolatilityConsistency Score

Sleeper

Strategy

A player who is being drafted later than their expected production warrants. Identifying sleepers provides draft value.

Snake Draft

Drafting

The most common draft format where the pick order reverses each round (1-12, then 12-1, then 1-12, etc.) to balance competitive advantage.

SOS

Analytics

Strength of Schedule. A metric measuring the difficulty of a team's upcoming opponents. Lower SOS (easier schedule) can boost fantasy production.

Related:Ensemble Projection

Standard Scoring

Scoring

The traditional fantasy scoring format without reception bonuses. Points are awarded for yardage and touchdowns only.

Streaming

Strategy

A strategy of picking up and dropping players weekly based on matchups rather than holding a permanent starter. Common for QB, TE, DEF, and K.

SuperFlex

League Types

A league format with an additional flex position that can include quarterbacks. Significantly increases QB value and draft strategy complexity.

Target Share

Analytics

The percentage of a team's total passing targets directed to a specific player. Higher target share indicates more opportunity for fantasy production.

TE Premium

League Types

A league setting that awards bonus points (usually 0.5-1.0 extra PPR) to tight ends to increase their value relative to other positions.

Tier

Drafting

A grouping of players with similar projected value. Players within the same tier are roughly interchangeable, while gaps between tiers represent value drops.

Trade Value

Strategy

The estimated worth of a player in trade negotiations, typically expressed as a numerical score for comparison purposes.

VAP

Analytics

Volatility-Adjusted Projection. A projection that accounts for a player's scoring variance, providing a risk-weighted expected output.

Related:VolatilityIRV

VBD

Strategy

Value-Based Drafting. A strategy that ranks players by their projected points above a replacement-level player at their position.

Related:VORPPositional Scarcity

Volatility

Risk

A measure of how much a player's weekly fantasy scores vary from their average. High volatility means unpredictable week-to-week production.

Related:Consistency ScoreSharpe Ratio

VORP

Analytics

Value Over Replacement Player. The number of fantasy points a player is projected to score above the best available replacement at their position.

Related:VBD

Waiver Wire

Waivers

The pool of unowned players available for pickup. Most leagues use a priority system or FAAB bidding to determine who gets claimed players.

Zero-RB

Strategy

A draft strategy that prioritizes WRs and other positions in early rounds, waiting to draft RBs until later rounds. Based on RB injury rates and WR consistency.
