LINEUP BUILDING WORKFLOW
NFL DFS Lineup Builder for Simple and Advanced Builds
A lineup builder should make the first build understandable and the fiftieth build controllable. Simple mode is for choosing a slate, setting a few preferences, and producing a legal lineup; advanced mode exposes portfolio-level rules.

What this guide answers
This page is for players comparing NFL lineup builders and deciding which controls they actually need before a DraftKings or FanDuel slate locks.
- Start with a verified salary slate
- Use simple mode to learn the player pool
- Use advanced controls for exposure and correlation
- Save assumptions so results can be reviewed later
A useful simple builder
A simple workflow should identify the platform and slate, show projections and value clearly, support locks and exclusions, and produce only valid rosters. It should also explain why no lineup can be built when the salary pool or projection model is incomplete.
When advanced controls matter
Multi-entry players often need quarterback stacks, opponent bring-backs, player exposure ranges, team caps, maximum ownership, and lineup uniqueness. Those controls are most useful when they express a contest thesis, not when every available switch is turned on at once.
Review before export
Check salary remaining, duplicated lineups, late-game flexibility, injured players, and the concentration of each game environment. An export is a handoff to the contest platform, not proof that the portfolio is sound.
Frequently asked questions
What is the difference between a builder and an optimizer?
A builder is the full lineup workflow. Optimization is one calculation inside it; research, constraints, review, and export are equally important.
Is simple mode only for beginners?
No. It is also useful for fast single-lineup work when advanced portfolio constraints would add noise rather than value.
