The thing is that the US team sports you can think of such Baseball or American Football, have nearly no popularity outside of the US. Maybe Baseball in places like Japan or Venezuela.
Maybe the only parallel to soccer I can think of is sports like Rugby in UK and some English-speaking countries, Cricket in India, and some sports endemic to countries (such as GAA in Ireland).
The best way to compare the US to other countries in a sport that is similar in terms of interest among other countries is something like Volleyball. Which the US tends to be very good at, with many major competitors. I can't think of anywhere that volleyball is a #1 sport that sees a lot of unstructured play.

All this was obviously about team sports.
