The American football (AFC) and National Football League (NFC), was created in 1920. In 1960, the NFL and the AFL merged to create today’s American Football Conference (AFC) and the National Football Conference (NFC). The two conferences were divided geographically in 1967. Each team plays its opponents twice each season (16 games per year). A total of 32 teams play 16 games per year, meaning that 4 games are played at each site location every week. Most weeks, 2 different teams will win their matchup, with 1 team winning 14 times out of 16 games, and the other team winning 12 times.
