For any week, the lineup page compares the lineup you have set on Sleeper with the best one the projections allow, scored with your league’s own settings (PPR, TE premium, superflex and the rest). When the best lineup projects less than a point more than yours, the swaps are listed as optional: at that size they’re coin flips, and Home counts your lineup as set.
- Suggested changes show each start/bench swap and the points it adds, how often the new starter out-scores the one going out, and each player’s likely range (on a phone the odds and ranges sit behind the Why button, so the swaps come first). When the player going out is on bye or ruled out, it says so instead. While games are on, only players who haven’t played yet are moved.
- Injury fixes: for each starter who won’t play, the best bench option, the free agent projected to score the most this week (never one who is out, on bye or whose game has started) and the cheapest trade for similar production. Once trades close, no trade is offered.
- Once games kick off, rows show the live box score; before that, the projected stat line.
- Soft and tough matchups: before kickoff, a player facing one of the six defenses that allow the most (or fewest) fantasy points to his position gets a tag, scored your league’s way from this season blended with last. On a computer, hover it for the numbers.
- Weather and game script: outdoors, a forecast wind of 15 mph or more, real rain or snow, or a low of 20°F or colder gets a tag (red where it hurts the position, like wind for a quarterback or kicker), and so does a spread of 10 points or more (a big favorite runs the ball, a big underdog throws). The forecast and the spread come from Sleeper’s schedule; on a computer, hover a tag for the reasoning.
- With the suggested changes, a line compares the two lineups as a whole: the chance each one beats this week’s opponent and its likely range (a bad to a good week), not just the projected totals. Try a swap does the same for any starter you take out and any bench player who can fill his slot.
- Vs projection: once a player has two games, a “+4.8 vs proj” line shows how far he has scored above (or below) Sleeper’s pre-game projection per game this season, when it’s 1.5 points or more. It’s a record, not a forecast: across two seasons, beating projections over half a season didn’t carry into the other half, so it isn’t part of the start/sit odds.
- "Get a second opinion" adds an AI read on injuries, matchups and recent form. It runs in the background. Once every game of the week has kicked off there’s nothing left to change, so it isn’t offered.
- "Left on bench" after kickoff shows points already lost to players who scored on your bench.
- Best ball leagues: Sleeper picks the lineup itself, so the page shows the numbers without suggested changes. Guillotine leagues show the chop line: the lowest score among the other teams this week; there the lineup comparison and Try a swap give each lineup’s chance of the week’s lowest score instead of a win chance.
- Dynasty Seer can’t change your lineup: Set it in Sleeper (the link at the top of the page) opens your team there, and you make the swaps in the Sleeper app.
