What this guide answers
This beginner-friendly guide explains the complete path from a salary file to a reviewed DraftKings or FanDuel lineup.
- Define the contest before choosing players
- Validate projections and salaries
- Use correlation intentionally
- Check injuries and lineup legality at the end
1. Set the decision context
Choose DraftKings or FanDuel, confirm the contest and slate, and note the lock time. Decide whether the goal is a stable cash construction, a single tournament entry, or a multi-entry portfolio.
2. Build around opportunity
Compare projection, salary, workload, game environment, ownership, and ceiling. Select a correlated core when the contest rewards first-place upside, then fill remaining positions without losing the lineup's scoring logic.
3. Validate and save
Confirm salary cap, positions, start times, actives, weather, duplicates, and late-swap flexibility. Save the model and settings used so the decision can be evaluated after the slate.
Frequently asked questions
Do I need an optimizer to build NFL DFS lineups?
No. It makes combination search and rule enforcement faster, but a manual build can follow the same research and validation process.
What should a beginner avoid?
Avoid mixing platforms or slates, relying on stale news, and treating a projection as a guaranteed outcome.
Use current data, not a frozen claim.
