Lineup Lab
Save your roster, set your league rules & scoring, and get weekly start/sit recommendations.
What is Lineup Lab?
Your weekly lineup consigliere. We blend data science (projections, injuries, opponent difficulty) with human overrides to get you the best combo of art + science.
- Search by player name (we map to Sleeper IDs automatically) or paste IDs.
- Save your roster once—update anytime for trades/waivers.
- Select the week and click Get Recommendation.
- A position-by-position starting lineup + bench.
- Confidence scores & rough tiers (A/B/C/D).
- Optional weekly email reminders with your lineup.
Keep several rosters and switch above. Pin players to FLEX and tweak your slot rules as needed.
Our advanced ensemble model combines industry-leading projection systems using weighted averaging, Bayesian updating, and regression stacking. It fuses machine learning predictions and expert consensus to reduce bias and boost predictive accuracy—basically, it’s like letting a bunch of data scientists set your lineup while you sit back and take the credit
Heads up: lineups refresh as projections and injuries update. You’ll get an email midweek and again only if your lineup meaningfully changes.
