The story begins, like many good stories do, in a pub. As early as the Middle Ages, Szymanski explains, the rough outlines of soccer—a game, a ball, feet—appear to have been present in England. But it wasn't until the sport became popular among aristocratic boys at schools like Eton and Rugby in the nineteenth century that these young men tried to standardize play. On a Monday evening in October 1863, the leaders of a dozen clubs met at the Freemasons' Tavern in London to establish "a definite code of rules for the regulation of the game.” They did just that, forming the Football Association. The most divisive issue was whether to permit "hacking," or kicking an opponent in the leg (the answer, ultimately, was 'no').
And the argument that (American) football hardly ever involves play with the foot doesn’t fly either—the forward pass and everything since is relatively new to the sport.
