Questions, corrections, or data tips? We read every message.
The NFL Analytics Textbook is an independent educational project. We welcome questions about the analytics, corrections, and data tips.
The best way to reach us is email: contact@nflanalytic.com. We aim to reply within a few business days.
Spotted a number that looks off? Email us the article title and, if you can, a link to the underlying data. Every statistic on the site comes from a script we can re-run, so well-specified corrections are easy to verify — and we’ll post the fix.
We can explain how a metric is built or what the data shows. We do not provide betting picks, fantasy lineup advice, or recommendations on individual wagers. For how the analytics relate to betting markets, see the betting education section, and read the disclaimer.
