Disclosure: I run Dynasty Dealer, a fantasy football site. We ran these studies and published the archive for free. What it is: the code and data behind eight pre-registered studies of public fantasy football leagues on Sleeper. Four on dynasty leagues: trading, rebuilds, how titles are built, and superflex QB shortages. Four on redraft leagues: draft position, Zero RB vs RB-heavy drafts, 0-3 starts, and how titles are built. Each study ran on the 2025 season and was repeated on 2024. What's inside: 26,500 public league IDs , drawn at random with a fixed seed. Dynasty: 5,000 for 2025 and 5,000
