About QuickManager: Fantasy for Sleeper

QuickManager runs all of your Sleeper leagues from one tab. Set lineups, handle injuries, work the waiver wire and review trades across every league at once, instead of opening them one at a time. AUTOSUB NFL teams announce inactives about 90 minutes before kickoff. If one of your starters is ruled out and you are not at your phone, that slot scores zero. Autosub watches the leagues you pick during that window. When a starter is ruled out, it puts your best available bench player in his place. It fills empty slots, and it can move players who are out onto IR to free up a bench spot. You decide how much it does on its own. Log only: records what it would have done and changes nothing. Approval: asks you before each change, with an optional timer that applies it if you have not answered in time. Away Mode: makes the changes without asking. Everything it does goes to an inbox, grouped so one injury across four leagues reads as one line. When it cannot fix a slot, for example because everyone who could play there has already kicked off, it tells you that too. It never makes waiver claims, never drops a player you have not marked as droppable, and never moves anyone off your taxi squad. Autosub runs while QuickManager is open in your browser, so leave the tab open on game day. Autosub is part of Pro. SLEEPER AUTOSUBS Sleeper lets you name a bench player to replace a starter who does not play. QuickManager now works with them instead of around them. In the lineup editor each starter has an autosub picker that lists only the players your league allows, and a bench player who is someone's autosub is labeled. Optimize can choose the best autosub for each Questionable starter, even moving him into a FLEX slot when that lets a much better player back him up. The Gameday board suggests an autosub, or a better one, for starters who are Questionable or Doubtful. Your autosubs stay yours. Anything that would remove one is shown first and asked about, and rearranging slots never removes one. Autosub leaves a ruled out starter to his Sleeper autosub unless you tell it to replace him, and it never replaces a starter whose autosub has already played, because only Sleeper can still swap that player in. LIVE SCOREBOARD Every matchup you are in, with live scores and your chance of winning from here. Open a matchup to see each player's points, projection and stat line as his game goes on. On a computer you can pop the scoreboard out into its own window and keep it on a second screen. LINEUP OPTIMIZER Scan every league and see how many points are sitting on your bench, then apply the best lineup everywhere with one click. It uses each league's own scoring and handles bye weeks and injuries. It never moves a player whose game has already started, and it can put your latest kickoffs in FLEX so you still have options after the early games. Open trades have an Analyze button that runs them through the trade simulator. GAMEDAY BOARD Every lineup you manage, in kickoff order, showing only what needs a decision: a starter who is out, an empty slot, or an upgrade worth making. Each move names both players and what it is worth in that league. Apply one, or tick the ones you like and apply them all. WAIVERS Put the players you want on one list and see which of your leagues each one is available in. QuickManager builds the claims and you choose the drops and bids. Edit or cancel claims you already sent. Free Agent Radar finds the best unowned players across your leagues, Lineup Upgrades points out the free agents who would actually start for you this week, and Mass Drop cuts a player from every league in one step. TRADES Find trade partners across all of your leagues and review every pending offer in one place. Accept, decline, counter or withdraw without switching leagues. Before you say yes, simulate thousands of seasons for both teams to see what the trade does to each side's playoff odds, and where each lineup slot ranks in your league before and after. POWER RANKINGS AND STANDINGS Simulate the rest of the season in every league for real playoff odds. See how your roster ranks at each position against the rest of the league, which of your leagues still deserve your attention, and full standings for all of them. Leagues that also play the league median every week are counted correctly. ROSTER HEALTH Every league is checked against its own IR and taxi rules. Move everyone eligible to IR in one pass. If a roster breaks its league's rules, QuickManager finds it and fixes what it can, and nobody is dropped unless you say so. FREE AND PRO The free plan runs the lineup, waiver, trade and rankings tools on up to five leagues. Pro adds all of your leagues, autosub and league filters, and starts with a 7 day free trial. PRIVATE Your Sleeper login stays in your browser. QuickManager has no server and does not collect your data. The extension talks to Sleeper directly from your own computer. QuickManager is an independent tool. It is not affiliated with, endorsed by or sponsored by Sleeper. The Sleeper name is used only to describe what the extension works with.
