Why roster context matters
Fantasy advice should know the team it is helping
A player ranking cannot see your bench, your opponent, your flex constraint, or the waiver cost of solving next week's bye.
Matchup-aware risk
A safer starter can be correct when you are favored, while a higher-ceiling flex may be worth the variance when you need an upset.
Opportunity cost
Waiver and trade recommendations account for what you would lose, not only what you might gain.
Season-long roster strategy
Lineup, waiver, and trade decisions are connected because one move can create or solve multiple roster problems.
Methodology and accuracy
Transparent inputs, probabilistic recommendations
LineupLab recommendations use projections, league settings, roster constraints, matchup context, injuries, byes, positional scarcity, opportunity cost, and confidence scoring.
The methodology page explains the recommendation framework. The accuracy page shows the reporting structure for backtesting and public model tracking without inventing performance data before it exists.
