Ground rules

The site is the league's record. The spreadsheet the league has kept since the beginning is a frozen input: it is read once, checked against Sleeper and the recovered Yahoo box scores, and never edited. Where the two disagree the site is right by definition, and the receipt is on this page.

The 2025 co-championship. Greg managed the roster through week 8 at 6-2; Drake took it from week 9, went 3-3 and won the final in week 17. Each is credited half a ring, and every table that counts rings carries ½ for both. The 2025 season counts the two of them as the one roster they were.

The 2025 XP return. Sleeper credited Ryan's week 13 lineup with 393.84 after a defensive extra-point return was scored as a touchdown many times over; the record counts 113.84. The Miami Dolphins that week is corrected from 290.00 to 10.00. The game against David M shows both figures, and the win stands either way.

The 2021 week 9 override. The league recorded Caleb over Jeff. A stat correction landed after the result was locked and left the raw score 103.03 to 103.63 the other way. The record follows the league, and the game page carries the note.

Yahoo scoring, recovered. The sheet never labelled it, so it was tested against the recovered box scores: 2017 half PPR; 2018 to 2020 full PPR, with -2 for an interception and no penalty for a missed kick in any of the four years. Player figures for those seasons are reproduced under those settings from nflverse play by play.

7 confirmed bookkeeping errors · the bracket is the proof

Where the spreadsheet's bookkeeping disagrees with the brackets Sleeper recorded. The site shows the bracket-verified value and marks the cell corrected wherever it appears.

Each note opens the game that proves it; each manager opens that manager's season.

Minor point differences

Sleeper's API reflects post-game stat corrections; the sheet recorded scores as they stood at the time. 29 rows, none of which changes a result.

Lost to time

2014 and 2015 are gone entirely: no standings, no scores, no rosters. 2016 keeps one fact, that David M won it, and nothing else. The league played those years on NFL.com, and the league page did not survive the platform's purge.

What would recover them is an NFL.com league id, the kind that sat in the URL of an invite email in the autumn of 2014. With one, the Wayback Machine can be asked for snapshots of that league's pages, and the seasons go back into the sheet in its own format. If one turns up in an old inbox, send it to the league's address and the three seasons come back on the next Tuesday.

Refreshing

A scheduled Action runs every Tuesday morning through the season, after the Monday night stat corrections settle. It pulls the week's matchups, rosters, transactions and player scoring from Sleeper, fetches the published tier lists, rebuilds the model, and reruns every check on this page. Nothing is edited by hand between runs, and the spreadsheet is never written to at all.
