Funny that neither tennis nor golf are a top sport anywhere despite having such worldwide appeal (well, mostly).
And, I get it, soccer is the most popular sport in the world and I really do try to like it, but is there any doubt that basketball and American Football are clearly more entertaining? Like, I am sure I am biased being from the States, but I had pretty equal access to all sports growing up and I can't understand soccer's wild popularity. If the field were like half the size with more scoring and actual contact/action, perhaps it would make a lot more sense to me.
As for the OP's question, I will take people's word for it on soccer. I will go with Yankees for baseball, Celtics for basketball, Patriots for football, and let's polish it off with Tiger for golf (because nobody has even remotely touched his level of popularity since).
