Fantasy projections that have to prove themselves.
Fantasy Score Predictor puts an independent projection right above ESPN's for every player, using a statistical model trained on five seasons of data. Then it grades both projections in public, every week.
No account, no ads, no tracking. Your league data never leaves your browser.
Illustration. Our number sits above ESPN's: green when we project more, red when less. Hover any number for its range and the reasons behind it.
Live scorecard
Every projection is recorded before kickoff and graded after the game against the points actually scored, in ESPN's default PPR scoring, for every player ESPN projects for 5+ points. Average miss is how far a projection lands from the real score, on average: lower is better.
Tested before it shipped
The model was trained on 2021–2024 only, then scored on 2025 and early 2026: 5,257 player-weeks it had never seen, using only information available before each game.
| Projection | Average miss | vs ESPN | Close calls right |
|---|---|---|---|
| ESPN | 5.34 | — | 55.9% |
| Sleeper | 5.35 | +0.1% | 56.1% |
| ESPN + Sleeper average | 5.30 | −0.7% | 56.5% |
| Fantasy Score Predictor | 5.16 | −3.4% | 56.9% |
- Biggest gains at RB and WR, where usage, Vegas lines and touchdown markets add the most. QB, TE and kicker projections are close to ESPN's.
- Close calls are pairs of players at the same position whom ESPN projected within 3 points of each other: how often the projection picked the one who scored more. That's the start/sit decision you actually face.
- Football is noisy. Even a projection that knew each player's true season average would miss by about 5.5 points a week. The goal is to be a little better, reliably, which is why it's graded in public.

A second opinion on every player
Our projection above ESPN's, colored by how much it differs. During games it becomes a live projection; after, the final score.
Floor, ceiling and the odds
Hover any number for the full range of likely scores, the chance of beating ESPN's number, and the chance of a big game or a dud.
Why this number
A plain breakdown of every driver: role and usage, opponent, Vegas, weather, injuries and the betting market's touchdown odds.
Matchup and win probability
Both lineups slot by slot with projected totals and a live win-probability bar, for any matchup in your league.
Lineup, waiver and trade advice
Start/sit swaps, add/drop moves and fair trade ideas, judged by your whole roster over the rest of the season, injuries and byes included.
A panel that stays put
Everything lives in a floating panel you can drag anywhere on the page. It stays open while you browse and remembers where you left it.
How it works
A trained statistical model, not a hunch. It starts from the experts and corrects them where data says they're predictably off.
Start from the consensus
The average of ESPN's and Sleeper's projections, re-scored with your league's own settings (PPR, half-PPR, 6-point passing TDs, custom D/ST rules).
Correct it with 34 pre-game signals
Snap and target share, opponent defense against the position, Vegas totals and spreads, weather at kickoff, rest and travel, teammates out and ESPN's own track record on that player. One model per position, trained on 30,000+ player-weeks.
Check the betting market
When prediction-market touchdown odds disagree with the projections, the number moves toward the market. Each price is frozen at kickoff.
Account for injuries and the game itself
Injury tags become a measured chance to play. During games, the projection updates from points scored, time left and the game script.
Private by design
- Your league data stays in your browser. The extension talks to ESPN directly with your existing login. It never sees your password, and your rosters are never sent anywhere else.
- No account, no ads, no analytics. There's no server behind the extension. Nobody, including the developer, can see who you are or how you use it.
- Only public data from other sites. Schedules, stats, odds and weather, requested without anything about you.
