HandcuffHero runs Pick Hoarders: five seasons, a 41–24 record, the 2024 title and 24 trades. Lately a win-now team that keeps buying wide receivers, with an aging core. They sell veterans dear and usually come out about 20% ahead, so lead with players who start now and ask for picks or young players back.

FAQ

Questions

Is the league scouting report free?

Yes. The league report and each owner’s scouting card are free and need no account. The full report on each owner, with every read and the plan to beat them in a deal, is in Dynasty Seer: your own report and one other owner’s on the Free plan, every owner’s on Pro.

Do I need my Sleeper password?

No. Your Sleeper username is enough. Dynasty Seer only reads public league data and cannot set lineups or send trades.

Can my league-mates see that I looked?

No. Nothing is sent to anyone. The report is a page with a link: your league sees it only if you share that link.

Where do the reads come from?

From your league’s public history on Sleeper: every trade, draft pick, waiver claim and matchup, for up to seven seasons. Player and pick values come from Dynasty Dealer, built from real Sleeper trades.

Which leagues work?

Any NFL league on Sleeper. Dynasty leagues with several seasons give the sharpest reads; a brand-new league has little history yet.
