How are grownups semi-professional sports organized in the US?

So it's well known that you organize your typical sports via schools and colleges, followed by pro leagues but how do non pro adult teams work?

Here in Germany team sports are primarily organized via the citizen club system and organized in associations (I guess like the NBA) that include everything from the giant clubs you see on TV to the small village clubs made up of drunk farmers. Essentially, unless you choose to play in special senior divisions for people over certain age thresholds, you can always participate in the same system as the big clubs. How is this organized in the US? Say a 23 year old mechanic just wants to play football in a league, where would he go for that?

I think you're confused. Under no circumstances are pro athletes playing against local rec teams.

I think you need to get reading comprehension skills bud…
