Player outcome ranges
Projected points, floor, median, ceiling, boom and bust probability, confidence, and volatility describe a range of possible player outcomes.
Building your winning lineupAnalyzing matchups, projections, and roster fit
LineupLab combines player outcome ranges, league rules, roster constraints, verified ownership, matchup context, team strategy, legal move generation, and simulations. The result is explainable draft, lineup, waiver, and trade advice—not a context-free score.
The engine keeps performance, market price, league value, team fit, strategic fit, actionability, and confidence separate so one weak signal cannot masquerade as a complete answer.
Projected points, floor, median, ceiling, boom and bust probability, confidence, and volatility describe a range of possible player outcomes.
Scoring, roster slots, flex and superflex rules, tight-end premium, league size, waivers, playoffs, and season type change replacement value and scarcity.
The full starting lineup, bench depth, injuries, byes, positional gaps, surplus, fragility, and known future picks determine whether an action improves this team.
An Auto-inferred or user-selected redraft, keeper, or dynasty preset defines the competitive window while weekly floor-versus-ceiling risk remains a separate choice.
Named waiver targets require confirmed availability, trade targets require known owners, lineup moves must be legal, and every add or acquisition includes what the team gives up.
Weekly matchup, playoff, title, and trade-acceptance estimates compare outcomes before and after an action while evidence coverage and confidence remain visible.
A team's season objective should not be rediscovered independently by the draft room, waiver board, Trade Center, lineup optimizer, and AI Coach. LineupLab resolves one shared policy and passes the relevant parts to each decision engine.
Redraft never receives dynasty-style retained value or a rebuild objective. Keeper recommendations balance this season with the limited set of assets that may carry forward. Dynasty preserves the full player and draft-pick timeline. Rebuilding and future-focused teams still receive the best legal lineup every week.
A probabilistic model can improve decision quality while still being wrong on individual outcomes.
Football outcomes depend on injuries, coaching decisions, weather, game script, touchdowns, and uncertainty that no product can fully know ahead of time. LineupLab should be treated as decision support: a structured way to compare options and understand the tradeoffs.
The same pipeline powers structured product surfaces and the live tools AI Coach can call, so conversational answers and on-page recommendations use the same current evidence.
Each product surface uses the shared foundation but asks a different decision question. This keeps the output specific without breaking consistency across the season.
The lineup optimizer fills legal starters and flex spots while respecting locks, injuries, opponent context, stack correlation, projection range, and the team's independent weekly risk posture.
The waiver engine verifies league-wide availability, scores legal add-drop pairs, protects current starters, and weighs FAAB, immediate need, breakout upside, and format-native future value.
Trade Center generates partner-aware packages, evaluates both rosters, estimates acceptance, and simulates weekly points, expected wins, playoff odds, title odds, and dynasty pick impact.
The draft engine combines value over replacement, roster fit, tier dropoff, ADP, expected next-pick availability, opponent pressure, keeper costs, dynasty value, and the selected draft plan.

Straight answers for fantasy managers evaluating the product before connecting a league.
Rankings describe players in a broad market. LineupLab evaluates a decision inside the user's scoring, roster slots, league format, current team, opponent, ownership, competitive window, and opportunity cost before recommending an action.
Yes. Redraft excludes retained-player and future-pick value. Keeper analysis separates current production from plausible keeper surplus. Dynasty keeps long-term player value, liquidity, age curves, and verified draft capital in view.
The selected or Auto-inferred preset defines the team's competitive objective and transaction priorities. Separate controls can tune weekly risk, acquisition pace, keeper value, dynasty asset timeline, and dynasty pick policy without overriding league rules, ownership, or legality.
No. Player outcomes, matchup results, trade acceptance, playoff odds, and title odds are estimates with uncertainty. LineupLab uses them to compare decisions and exposes confidence or evidence limits rather than promising a result.
