Overview

This skill analyzes matchups, injuries, weather, and Vegas lines to produce data-driven sit/start recommendations with confidence levels for NFL, NBA, MLB, NHL, and soccer. It delivers clear reasoning and actionable lineup moves tuned for daily and season-long fantasy formats. The output emphasizes explainable decisions so managers can act quickly before locks.

How this skill works

The optimizer ingests team matchups, player injury reports, weather and park factors, and betting lines to estimate each player’s projected impact. It ranks roster decisions by expected fantasy points delta and assigns a confidence score based on data quality and variance. Recommendations include alternative options and brief rationales to support lineup changes.

When to use it

  • Setting daily lineups before game lock for DFS or daily fantasy platforms
  • Finalizing season-long weekly lineups based on matchups and injuries
  • Adjusting rosters after late injury news or unexpected weather alerts
  • Comparing two close-start candidates with confidence-weighted guidance
  • Preparing substitution plans for multi-game slates or double-headers

Best practices

  • Provide full lineup and available bench players for context to get tailored swaps
  • Share league scoring settings (PPR, roto categories, H2H points) so projections align
  • Check for late-breaking injury updates and re-run optimizer near lock time
  • Use confidence levels to prioritize urgent moves and conservative benches
  • Combine optimizer output with your own roster rules (min/max games, positional limits)

Example use cases

  • Daily NFL: Decide between two WRs with similar projections but different weather and opponent pass defense
  • NBA nightly: Choose whether to start a player on a back-to-back with uncertain minutes and assign a confidence grade
  • MLB start/sit: Recommend streaming a pitcher based on park factors, weather, and opposing lineup strength
  • NHL roster: Sit a skater against a top penalty kill team while highlighting a value replace
  • Soccer DFS: Recommend captain and vice-captain considering form, matchup, and expected minutes

FAQ

How are confidence levels determined?

Confidence is derived from data freshness, injury certainty, variance in projections, and matchup volatility; higher confidence means consistent signals across those inputs.

Can it handle custom scoring systems?

Yes—provide your league scoring settings and the optimizer will adjust projections and recommendations accordingly.
