Dont have the data, but the study admits it didnt control for velocity. If you have studies that control for velo in adults, post em up.
If its just overuse alone, catchers would have similar rates of injury, as they have similar (if not greater) throwing rates
So you want to control for velocity in adults. How would one go about doing that? Did kids used to have TJS? No. Did they used to pitch year round? You’re just being dense here. I am sure velocity plays some role but the bottom line is kids pitch lots more at a younger age. It’s wear and tear. Common sense.
