I was unaware the passage to manhood was in high school. I always figured it was based on being self-sufficient meaning providing your own food, shelter, and basic needs. I don't know too many high schoolers that don't live at home. Competing is fine if the sides are relatively equal - not if its a gross mismatch concerning children.
Kids get hurt in high school football all the time. Usually has absolutely nothing to do with your opponent outweighing you... They weren't risking injury, they were risking embarrassment. You learn more from failure than success.
