Fantasy Football Glossary
Comprehensive reference of 42 fantasy football terms, metrics, and concepts used throughout the Ronin Almanac.
ADP
DraftingAverage Draft Position. The average pick number at which a player is selected across multiple drafts. Used to gauge market value and identify value picks.
Boom/Bust
RiskA player who has high variance in weekly scoring. Boom weeks produce elite numbers while bust weeks are well below expectations.
Bye Week
GeneralThe 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.
Ceiling
ProjectionsThe maximum realistic fantasy point output a player could achieve in a given week or season. High-ceiling players have explosive upside potential.
Consistency Score
AnalyticsA metric (0-100) measuring how reliably a player produces fantasy points week to week. Higher scores indicate less variance and more predictable output.
Dynasty League
League TypesA 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
AnalyticsA forecasting method that combines multiple models (EWMA, RTM, 3-year average, SOS) with optimized weights to produce a single, more accurate projection.
EWMA
AnalyticsExponentially Weighted Moving Average. A statistical method that gives more weight to recent data points. Used in the Ronin projection engine to capture trending performance.
FAAB
WaiversFree Agent Acquisition Budget. A dollar amount allocated to each team for bidding on free agents throughout the season. Replaces traditional waiver priority systems.
Flex
GeneralA roster position that can be filled by a RB, WR, or TE (and sometimes QB in SuperFlex leagues). Provides lineup flexibility.
Floor
ProjectionsThe minimum realistic fantasy point output a player is expected to produce. High-floor players provide safe, consistent production.
Game Script
AnalyticsThe flow and situation of a game that affects player usage. Teams trailing tend to pass more, while teams leading tend to run more.
GSI
AnalyticsGame 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
ScoringA 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
StrategyA 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 TypesIndividual Defensive Player. A league format where managers draft individual defensive players (DL, LB, DB) instead of team defenses.
IRV
AnalyticsInjury Risk Volatility. A multiplier applied to projections based on a player's injury history and current health status. Higher IRV reduces projected output.
Keeper League
League TypesA 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
StrategyThe concept that positions with fewer elite options (like TE) are more valuable to draft early because replacement-level production drops off significantly.
PPR
ScoringPoints 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)
AnalyticsA statistical measure (0-1) indicating how well a model's predictions match actual results. Higher R² means better predictive accuracy.
Range of Outcomes
ProjectionsThe spread between a player's floor and ceiling projections. Wider ranges indicate more uncertainty and risk.
Redraft League
League TypesA 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)
AnalyticsThe statistical tendency for extreme performances to move toward the average over time. Players with outlier seasons are expected to regress.
Roster Management
GeneralThe ongoing process of managing your fantasy team's lineup, including start/sit decisions, waiver wire pickups, and trade negotiations.
Sharpe Ratio
AnalyticsA risk-adjusted performance metric borrowed from finance. In fantasy, it measures points scored relative to scoring volatility. Higher is better.
Sleeper
StrategyA player who is being drafted later than their expected production warrants. Identifying sleepers provides draft value.
Snake Draft
DraftingThe 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
AnalyticsStrength of Schedule. A metric measuring the difficulty of a team's upcoming opponents. Lower SOS (easier schedule) can boost fantasy production.
Standard Scoring
ScoringThe traditional fantasy scoring format without reception bonuses. Points are awarded for yardage and touchdowns only.
Streaming
StrategyA 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 TypesA league format with an additional flex position that can include quarterbacks. Significantly increases QB value and draft strategy complexity.
Target Share
AnalyticsThe 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 TypesA 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
DraftingA grouping of players with similar projected value. Players within the same tier are roughly interchangeable, while gaps between tiers represent value drops.
Trade Value
StrategyThe estimated worth of a player in trade negotiations, typically expressed as a numerical score for comparison purposes.
VAP
AnalyticsVolatility-Adjusted Projection. A projection that accounts for a player's scoring variance, providing a risk-weighted expected output.
VBD
StrategyValue-Based Drafting. A strategy that ranks players by their projected points above a replacement-level player at their position.
Volatility
RiskA measure of how much a player's weekly fantasy scores vary from their average. High volatility means unpredictable week-to-week production.
VORP
AnalyticsValue Over Replacement Player. The number of fantasy points a player is projected to score above the best available replacement at their position.
Waiver Wire
WaiversThe pool of unowned players available for pickup. Most leagues use a priority system or FAAB bidding to determine who gets claimed players.
Zero-RB
StrategyA 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.
