Where the numbers come from and what we changed.
Play-by-play, participation, charting and Next Gen Stats data come from the nflverse release files, published under the Creative Commons Attribution 4.0 license.
Changes made: Stats Pirates loads those files into its own database, matches players and teams across seasons, and computes rates, splits and leaderboards. Nothing here is an official NFL statistic, and the NFL does not endorse this site.
