BUILT ON REAL DATA, NOT OPINIONS

Most dynasty fantasy football tools do the same thing: show you a value chart. They tell you what a player is “worth” based on consensus rankings or crowdsourced trade data, and leave you to figure out the rest. The advice is generic. The analysis is surface-level. And nobody can tell you whether what they’re recommending actually works — because nobody has checked.

That’s the gap Dynasty Trade Maker was built to fill. We don’t just tell you what players are worth. We tell you what actually wins championships, because we went and looked.

We crawled thousands of completed Sleeper dynasty leagues — leagues that played a full season and crowned a champion. From those leagues, we pulled everything: every roster, every trade, every draft pick, every transaction. Then we did it again for the previous four seasons, building a historical dataset that tracks how championship teams are actually constructed over time.

The result is the largest dynasty championship dataset in fantasy football. Not a survey. Not a poll. Not what experts think should work. Real outcomes from real leagues, at a scale nobody else has.

Every claim on this site is backed by data we can show you. When we say 78.4% of champions had a top-10 running back, that’s not a guess — it’s a count from 9,983 real championship rosters. When we say the value “loser” in lopsided trades wins titles more often, that’s measured across 27,485 real trades. When we say rebuilds average 1.64 seasons, that’s from tracking thousands of real rebuild-to-title runs.

We publish our methodology. We note our caveats. We tell you when a number is cross-sectional, when a sample is small, and when survivorship bias applies. The goal isn’t to sound impressive — it’s to give you information you can actually trust and act on.
