Well football is a great sport for a lot of people, as they spend lots of money to watch it, so they could see their team win, once the winning team wins people goes home to talk about it. The sport is great as well, because everyone on the team works as one, and it builds character for the person playing it, as it is a great stress reliever for people who has lots of stress.
He could learn teamwork, He could relieve some stress, and lastly, it can build his character.
One reason why I would allow my son to play football is because it teaches players teamwork
