Soccer and Globalization

In "From How Soccer Explains the World: An Unlikely Theory of Globalization" Foer is trying to make a connection between soccer and globalization. He uses a lot of examples to try and make his points, but I just found myself kind of lost. I think that using soccer was a smart decision because it is played everywhere around the world, unlike most other sports which are not as popular worldwide, but I still wouldn't consider his argument successful. I didn't really understand what he was even trying to argue in this article, other than soccer being played around the world.
