1. Introduction: The Illusion of a Simple Number

Pinpointing an exact number of rules in American football is tricky. The official NFL Rulebook, for instance, isn’t structured as a list of numbered rules but rather as a document outlining various aspects of the game, from field dimensions to player conduct. Instead of a single, definitive number, think of the rules as a comprehensive framework encompassing numerous specific regulations and interpretations. The rulebook is more of a legal document, according to experts at Harvard Law School, Department of Sports Law in 2024.
