Part of the confusion is that the United States (and yes, Canada) refers to "football" as American football, where an oval-shaped football (also known as a pigskin) is used. "Football", to the rest of the world, is "Association football", where a round ball is used. The U.S. and Canada call this kind of football with a round ball "soccer". And if that isn't confusing enough, "American football", to the rest of the world, is called "gridiron". Hence the absurd confusion whenever someone says "football", which is why I, rather than take sides, used "association football" or "football/soccer" in this edition of TSP.
