Beyond me. Not understood. I don't get it. I don't get the attraction, the excitement, the hype. Which is all purely subjective, of course. I see two teams of idiots chasing a ball. Haven't they got better to do?

Can you even tell the difference between American football and association football (soccer)? Seems doubtful. You certainly have no basis to discuss the comparative risks between the two. Maybe the people that play these games don't want to sit around in front of a computer all day atrophying and getting fat and sick. Maybe they like to be healthy and have fun. That doesn't make them idiots. It just shows your intolerance to something that doesn't even affect you.

May I humbly suggest a basic course of reading comprehension?

You're the one that needs to learn how to write properly.
