What sports does the average american play ?
It’s just that your sports all seem to be very elitist to play football you need to be at least over six ft tall as with basketball, here in england anyone can play almost any of our national sports even rugby (certain positions) do you play much soccer as you call it.
I suspect that if you went by the number of participants for all ages, it would probably be basketball. Softball (like baseball except with a larger ball and underhand pitching) would probably be second. Soccer is popular amongst kids, but is not (yet) played much by adults.
And you don’t need to be six feet plus to play basketball — that’s only for professionals, and not even all of them (specifically the guards) are that tall. I played basketball in high school and college (house league) — all 5’11” of me. And I played forward.
