This is a simple question with a really complicated answer. But we'll try to keep it simple.
Our data collectors are watching games as they happen and collecting data with each play. This means that some game data is available within our systems within minutes of the play happening. However, other data is only available after the game, once we've seen the All-22 tape. On top of that, we have data quality and data validation steps to ensure what we collected is, indeed, accurate.
This takes a lot of work to get right.
In practice, this means:
- All NFL game data (including PFF grades) is available by Monday, noon EST (with the Monday Night game available by noon on Tuesday).
- Most data for College teams (the FBS schools), as well as CFL and XFL data is available by 8am EST the day after game day. PFF Grading and our All-22 film review often happens after that, though.
- For FCS programs, game data may not be available until later in the week, but should always available before the start of the next week's slate of games.
We do data quality checks both in-season and over each offseason, so data may change past these dates if we ever find a mistake. (This is rare, but it does happen.)
