The National Football League (NFL) is a professional American football league consisting of 32 teams, divided equally between the National Football Conference (NFC) and the American Football Conference (AFC).
The exact number of clubs varies from year to year as clubs join and leave leagues or fold altogether, but an estimated average of 15 clubs per division implies that more than 7,000 teams of nearly 5,300 clubs are members of a league in the English men's football league system.
