Adams, I disagree about baseball. The repetitive throwing activity has caused children I am aware of to have to have surgery after repeatedly pitching multiple games for their schools, travel teams, all-star teams, etc. Doctors have to shut them down when they are 12 years old because their parents push them so hard that their elbows can’t take it. Ever heard of TENNIS ELBOW? Injuries like that are almost impossible to heal from and even surgery is not a 100% cure-all. These types of injuries occur with repetitive activities of the elbow, so not just tennis is a culprit.
But, yes, you’re right about football- totally barbaric. What about soccer? Not so simple a call, but the number of high school kids I’ve seen with injuries is appalling. People just don’t pay attention where they’re running. I could go on and on, but you get my point.
