Overview: Most teenagers play sports and enjoy playing them, but can sports be too dangerous?
Explanation: Young children learn their own limits and strengths through play with others and  they also learn valuable social lessons about acceptable behavior and the rights of others. Although, Injury Network has called for the elimination of violent contact sports, especially when it comes to teenagers. Effects of athletic and sports concussions can be severe and even, in rare situations, deadly. 
Claim: Teenagers should be allowed to play sports. Sports are not all about getting injured, its about building your own character, and getting through the times when you get hurt and gaining the courage to try again.
