Questions, corrections, or data tips? I read every message.
The NFL Analytics Textbook is an independent educational project written by one person. I welcome questions about the analytics, corrections, and data tips.
The best way to reach me is email: contact@nflanalytic.com. I aim to reply within a few business days.
Spotted a number that looks off? Email me the article title and, if you can, the figure you get instead. Every statistic on the site is computed from the public game log that ships with the site at /data/, so a well-specified correction is quick to check against the same file — and I post the fix and say what changed.
I can explain how a metric is built or what the data shows. I 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.
