Fantasy Football Start/Sit, Trade & Lineup Optimizer
Enter your whole fantasy football roster and league setup — any slots (QB to superflex to IDP), any scoring — and get a Smart Score lineup that weighs projections, recent form, matchups, injuries and weather, with side-by-side player comparison. Free, no signup.
Full PPR — every projection and past result is rescored from raw stats with these values.
Data updates itself: Sleeper projections, results and injury tags refresh automatically all season (cached 12 hours — tap the refresh icon for the latest). Weather comes from the ESPN scoreboard. Smart Score = projection rescored to your league × recent form × matchup × injury × weather.
What Is the Fantasy Football Start/Sit, Trade & Lineup Optimizer?
The Advanced Start/Sit & Lineup Optimizer sets your whole lineup at once — and ranks players on more than a raw projection. Every player gets a Smart Score built from five live factors: the weekly projection rescored to your league's exact custom rules (per-yard values, PPR, TE premium, yardage bonuses, kicker distance tiers, team-defense and full IDP categories), recent form from the last three weeks of actual results scored your way, how generous the opposing defense has been to that position, injury status, and the game-day weather forecast (domes stay neutral). Set any lineup shape — QB, RB, WR, TE, three kinds of flex, superflex, K, DEF, IDP slots and bench spots — add your full roster with player photos, and the tool fills the best legal lineup, explains every call with factor chips, and gives each bench player a start/sit margin. Lock any player in or out to override a call. A Compare tab puts up to four players side by side, and the Trade Analyzer values any deal — including multi-player packages — using points above a waiver-wire replacement, Vegas lines, remaining weeks and upcoming schedule. Everything saves in your browser, with one-click JSON export/import to move devices.
How It Works
Pick your week, search and add each player on your team, then set your lineup slots (or tap a preset — Standard, 3 WR, Superflex, 2 QB, IDP) and bench size. Open League Scoring to match your league exactly. The optimal lineup, factor chips and bench verdicts update instantly; tap player chips to send up to four into the Compare view. Data refreshes itself all season — the refresh button forces the very latest.
When to Use It
Every week before lineups lock, after trades or waiver pickups reshape your roster, or when a questionable tag, brutal matchup or stormy forecast has you second-guessing a starter.
Frequently Asked Questions
- Is this just sorting by projected points?
- No. Projections are the starting point, but the Smart Score also weighs recent form (hot and cold streaks from actual results scored with your rules), how many points the opponent's defense has allowed to that position, injury status, and outdoor weather. Each factor appears as a chip so you can see exactly why a player ranks where they do — and override with your own judgment.
- Can it handle my league's weird lineup?
- Yes — set any count (0–6) for QB, RB, WR, TE, W/R flex, W/T flex, W/R/T flex, superflex, K, DEF and IDP slots (DL, LB, DB and IDP flex), plus bench size. Two-QB, three-WR, no-kicker and full IDP formats all work.
- Do I need to update the data myself?
- No. Projections, results, injury tags and weather come from free public feeds (Sleeper and ESPN) that update continuously through the season. The tool caches for 12 hours; the refresh button pulls the very latest before you set your lineup.
- Will I lose my team if my browser clears?
- Your roster, slots and scoring auto-save in your browser, and the Export button downloads them as a JSON file. Import that file on any browser or device to pick up right where you left off.
