Enter your Sleeper username to pull in your leagues.
For leagues the board can't read yet (like Yahoo). Type your starters and your opponent's; it scores live with the United for Rooder (Yahoo) rules.
On Yahoo, open this week's matchup page, select all (Ctrl+A or long-press → Select all), copy, and paste here. Or paste a screenshot right into this box (Ctrl+V), or upload one. Rooder picks out the players and fills both lineups, then you check them and save.
FantasyPros already syncs your Yahoo leagues. Download each team's roster there and drop the files here. Rooder matches the players and keeps the rosters on this device only.
Classic NFL: QB, 2 RB, 3 WR, TE, FLEX, DST. Start typing and pick a player from the list.
Copy your lineup from DraftKings (or paste the CSV from Lineups → Export to add every lineup at once) and drop it here.
