What is the highest position in a sports team?

so the captain tells the coach what to do, really?

Many teams in sport function without a captain, but there is always a coach/manager. This question is written to split hairs and banter words. Bad form.

I answered " Coach". I believe that the way the question is written that I answered correctly.

The coach selects and appoints the Captain . The captain doesn’t select and appoint the coach . Where is the power?
