Fantasy football basics
Updated Aug 14, 2026Draft a roster. Score real games. Manage every decision.
Fantasy football turns real NFL player performance into points for a roster you manage. You draft or acquire players, choose a legal lineup, compete against another manager each week, and improve the team through waivers and trades.

League setup
Every fantasy league is a shared ruleset and player market.
The commissioner creates the competition, but the rules determine how managers value positions and build teams.
A league defines the number of teams, roster size, starting positions, bench, scoring, schedule, waivers, trades, and playoff format. Managers then draft from the same pool of NFL players. Once a player is rostered, another team must usually trade for that player or wait until the player is dropped.
Common lineups include quarterbacks, running backs, wide receivers, tight ends, and flex positions. Superflex leagues allow a quarterback in an additional flex spot, which usually makes quarterbacks more valuable.
Draft
Managers take turns selecting available players until every roster is filled, using a snake, auction, or other draft format.
Roster and lineup
The roster contains every player you control; the lineup is the eligible group whose statistics count for the current matchup.
Scoring
NFL passing, rushing, receiving, kicking, and defensive results become fantasy points under the league’s scoring settings.
Weekly season
Set the lineup, manage availability, and win matchups.
Most leagues use head-to-head weekly matchups before a playoff bracket determines the champion.
Before games begin, managers move eligible players into starting slots and account for injuries, bye weeks, roles, and matchups. Players on the bench remain rostered but normally do not add to that week’s score.
When needs change, managers can claim unrostered free agents through the waiver system or negotiate trades with other teams. League deadlines and review rules determine when moves become active.
Start and sit
Choose the legal lineup expected to score best while accounting for availability and the league’s scoring rules.
Waivers
Claim available players using priority, free-agent budget, or the waiver method selected by the league.
Trades
Exchange players or, in many dynasty leagues, future rookie picks when both managers accept the terms.
League formats
Redraft resets. Keeper retains a few. Dynasty keeps the team.
The amount of roster continuity changes how managers value age, draft picks, and future production.
Redraft leagues select new rosters each season, so the primary goal is current-year points. Keeper leagues let managers retain a limited number of players, often with a cost. Dynasty leagues keep most or all of the roster and add rookie drafts, making future value and long-term team building central.
Dynasty managers still try to win weekly matchups, but they must also decide when to contend, rebuild, trade veterans, acquire picks, and protect future flexibility.
Redraft
Build for one NFL season, then return most or all players to the next draft pool.
Keeper
Carry a limited group of players into the next season under league-specific costs and restrictions.
Dynasty
Retain the roster across years, draft incoming rookies, trade future picks, and manage a multi-season competitive window.

Common questions
Direct answers, without false certainty.
How do you win fantasy football?
Score enough points to win weekly matchups, qualify for the playoffs, and win the playoff bracket. Strong managers also improve through waivers, trades, lineup decisions, and rule-aware roster construction.
Do bench players score fantasy points?
They generate statistical results, but those points normally do not count toward the fantasy matchup unless the league uses a special best-ball or bench-scoring format.
What is the difference between dynasty and regular fantasy football?
Most regular redraft leagues reset rosters each season. Dynasty leagues retain most or all players, hold rookie drafts, allow future-pick trading, and reward multi-year roster strategy.
Is Sleeper a fantasy football league platform?
Yes. Sleeper hosts fantasy leagues and their rosters, scoring, waivers, trades, schedules, and chat. rosterrr uses public Sleeper league data in a separate read-only dynasty analysis workspace.
