About Depth Room who runs it and how it works

What the site does

A depth chart says who is listed first. Depth Room puts next to it who has been on the field, game by game, for every team in the league and 2,559 players. Where the list and the field disagree, the page says so.

The site also keeps the history of every team since 1999, a model that estimates the next game and the rest of the season, and a public record of how those estimates turned out.

Where the numbers come from

Every figure comes from a public source and is recomputed each day by the same program. Nothing is typed in by hand. The methods page names each source, explains each measure and shows how the model did on games it had never seen.

How the articles are written

Articles are drafted by an AI system from the numbers on this site, following a written set of editorial rules. Each team named in an article links to the page its figures come from. Before a piece is published, a program checks its links, its header, the team records it states and its wording.

The rules are short. An article states one finding and says how it was counted. It uses no anonymous sources and no rumours, because the site has neither. An estimate is always called an estimate.

What the site does not do

It does not break news and it has no reporters at team facilities. Its estimates describe chances and are not advice of any kind.
