What it can do

• Link with just your Sleeper username. No password. It's read-only and safe: we can see your league, nothing else.
• All your 2026 NFL leagues, each on its own tab, plus an overview of lineup problems across all of them.
• Start / Sit using our blended data: FantasyPros experts, ESPN projections, Vegas team totals, snap counts and target share, weather, injuries and byes, scored with your league's own rules (PPR, half PPR, standard, superflex, TE premium, roster spots).
• Trade ideas with your real league-mates, using SportsMafia Trade Desk values, aimed at trades that help both teams.
• Waiver pickups for your roster's needs, plus Sleeper's most-added and most-dropped players today.
• This week's matchup: your projected score against your opponent and your win chance, plus how much your best lineup would add.
• Power rankings for every team in your league, and team strength by position compared with the rest of the league.
• Playoff outlook: your playoff chances from 2,000 simulations of the rest of the season, using the real Sleeper schedule.
• Recent league moves, with a grade for every trade based on today's Trade Desk values, including draft picks in dynasty leagues.
• Lineup alerts: a red banner on My League, and an on-site alert (the bell, never email), when one of your starters is Out, Doubtful, on IR, ruled inactive for the game (inactives come out about 90 minutes before kickoff) or on bye, with the best healthy bench player to start instead. At most one alert per player per week. Turn site alerts on or off at the top of My League.
• Live matchup on game days: both teams' live points from Sleeper, who's still left to play, and your win chance as games go on. It updates about every 2½ minutes.
• Trade checker: build any trade with a league-mate, players and draft picks on both sides, and get a grade for each team with a short explanation. It accounts for your league's scoring, each team's needs and roster spots.
• FAAB bid advice: suggested bid ranges for the top pickups based on your budget, everyone else's budget and the player's value. Leagues without FAAB get waiver-priority advice instead.
• Drop candidates: your lowest-value bench players, each paired with a better free agent when there is one.
• Scouting report on this week's opponent: their lineup, strengths and weak spots, injuries and their last 3 scores.
• Playoff schedule strength: how tough each of your players' matchups are in your league's playoff weeks, and where your roster ranks.
• Rivalries: your head-to-head record against each league-mate and your biggest wins, going back through the earlier seasons of your league on Sleeper.
• Linked members leaderboard: every linked member's Sleeper teams ranked by record and points (Sleeper team name and site username only, members only). You can hide yours. See the leaderboard.
• League clubhouse: one members-only thread per Sleeper league in the League Clubhouses forum, for league-mates to talk. Tap "Open your league's clubhouse" on My League; if it's already open you go straight to it.
• Stays linked to your SportsMafia account until you tap Unlink.
• Works on phones as well as computers.

What it can't do yet

• Set your lineup or make moves for you. Sleeper only lets approved partners (like FantasyPros) do that, so you still make your moves in the Sleeper app.
• ESPN or other fantasy apps. Sleeper only for now.
• Alerts don't come by email or phone notification, only on the site.
• Live scores can be a couple of minutes behind the Sleeper app.
• IDP (defensive) players aren't rated.
• Trade ideas are mostly 1-for-1 players (use the trade checker for bigger deals). In dynasty leagues we may add a draft pick to even things out; we don't build big multi-player deals yet.
• Trade grades use today's values, not the values on the day the trade was made.
• Kicker and defense ratings are rough.
• Our data refreshes about 6 times a day. It isn't live during games.
• NFL only.
