NFL DFS Optimizer — Week 6 2026

No. This tool only helps construct and copy a lineup. It does not log into DraftKings or FanDuel, submit entries or place wagers.

The site administrator manually uploads the weekly DraftKings salary CSV and the detailed FanDuel projection CSV. FSN stores normalized salary data and translates the imported football-stat expectation into the scoring format used by each platform.

The FanDuel projection CSV does not carry an explicit position field. FSN matches positions against the same-week DraftKings pool and the site’s NFL roster cache. Any unresolved player stays visible but cannot be added until the position can be verified.

FSN does not simply average last week’s fantasy points into the forecast. It uses finalized attempts, carries and targets to detect role changes, applies a capped adjustment to the forward projection, and shows recent production separately. Only games before the target week can influence that week.

Floor, projection and ceiling show a practical low-to-high range from modeled player outcomes. The value-hit and risk numbers show how often a player strongly beats or falls short of salary expectations.

Each matchup runs 1,024 correlated outcomes. Team scoring, passing, rushing and game script move related players together, helping identify quarterback-pass catcher stacks, opposing bring-backs and games with more shootout potential.

The slate guide identifies those formats, but FSN does not reuse multi-game salaries for them. A separate Showdown/Single Game salary pool is required because platform-specific single-game salaries and athlete pools can differ.

FSN matches the current NFL injury report to the weekly player pool. A player marked Out is removed from generated lineups, while questionable or doubtful listings reduce expected availability conservatively. When a meaningful absence opens likely workload for teammates, FSN applies a capped role adjustment before rerunning the player and game simulations. Imported salaries are never changed.

Best Projection maximizes expected points. Safer Build gives more weight to floor and lower bust risk. High Upside leans toward ceiling and value-hit probability. Stacked Tournament also rewards quarterback-pass catcher stacks, opposing bring-backs and estimated field leverage. FSN's popularity estimate is a model, not actual contest ownership.

FSN creates a synthetic field from the selected salary pool using estimated player popularity, legal roster rules and common stacking behavior, then compares your lineup across modeled slate outcomes. Top-10% and top-1% rates are scenario-model results, not actual contest odds, ownership, ROI or payout predictions.

You can ask for up to 20 lineups using normal DFS language: cash, GPP, single-entry, 3-max, 20-max or MME; lock, fade, core, prefer, underweight or set player exposure ranges; require uniques or cap shared players; request skinny, double, triple, game or onslaught stacks, bring-backs, naked quarterbacks, secondary correlations and RB+D/ST; cap players by team or game; control salary used, positional spending and FLEX; set estimated-popularity and low-owned-player rules; request projection/value/game-total thresholds; preserve started players for late swap; and create player-group rules such as at-most-one, exactly-one or conditional pairings. FSN shows the rules it recognized and warns when a request depends on data this browser optimizer does not currently enforce.
