How First Down
works.

First Down is a set of free fantasy football tools for Sleeper leagues, plus an NFL matchup lab. These guides explain what each tool does and how it decides.

• LineupThe highest-scoring starting lineup for any week, with your league’s scoring and flex slots.
• WaiversFree agents ranked by how much they improve your best lineup, and who to drop.
• TradeBoth teams’ best lineups before and after a trade, week by week.
• ByesWhich weeks your lineup will have holes, so you can plan ahead.
• Start / SitTwo to four players compared on projection, form, matchup and injuries.
• Matchup LabTwo NFL teams, each offense against the other defense, with player box-score totals.

What the league tools have in common

Lineup, Waivers, Trade and Byes work on your real Sleeper league. You only type your public Sleeper username, with no password and no login. Everything is computed with your league’s scoring settings and roster slots. Players are judged by how they change your best possible lineup, solved exactly, not by raw points. A great player stuck on your bench adds nothing, and the tools reflect that.

First Down never changes anything in your league. It reads public data and shows you the result.
