About
Every league has one person who keeps the record.
LOL SO COSMO started in 2014 on NFL.com, moved to Yahoo in 2017 and to Sleeper in 2021. Its history lived in a Google Sheet that Austin Kilgore, a manager in the league since 2017, kept by hand.
In August 2026 he built a site from that sheet and from every box score the platforms still held. The build found seven bookkeeping errors in twelve years of the sheet, and the league ruled that the site, no longer the sheet, was the record.
Recordbook is that site, rebuilt so any league can have one.
What it stands on.
- The record must be right. Every figure is checked against every source that has it. Disagreements are explained on the page, never smoothed over.
- It works with no writing. The archive, the records, the tools and the votes stand on their own. Writers are a layer on top, and any league can turn them off.
- The league's name goes on it. Your site carries your name and colors at your address. Recordbook is a line in the footer.
- Deep history beats instant setup. If your league's records exist anywhere, the plan is to get them. Gaps are marked, never guessed.
- The facts do the trash talking. A record changes how a league behaves. Losers stay engaged when the losing is documented well.
The company.
Recordbook is made by Greenpath Labs, Austin Kilgore's studio.
The first league
The founder is sixth of twelve in luck.
Austin Kilgore keeps the spreadsheet for a league founded in 2014. Recordbook started as a site for that league and became a platform when it turned out every league has someone like him. His own manager page shows a Luck Index of 51, sixth of twelve, and a Skill Index of 59, first of twelve. He would like you to focus on the second number.
