I have a peruvian (not athletic/nerdy) friend who moved to the us a while ago. (I played through college) his son randomly started playing football his sophmore year after getting beaned by a baseball and felt baseball was more dangerous. About junior year the kid was having some issues at home. Dad didn't know what to do. I said email the coach. He's like what will that do. I was like coach can make him run (corporal punishment) and take away things. Emailed the coach. Coach was like "I'll have a chat with him". Next day he said son came home and apologized to him. Cleaned up amazingly instantly (great kid). Pretty sure it was literally just a talk from another respected figure (who likely said maybe you should play less or miss practice while you sort this out.
