Well Bobblehead,
That is the funny thing about scientific studies. They tend to change over time. You never know and every kid is different. Maybe the difference in arm injuries is something little like max effort pitchers get hurt the most and what they throw and how often doesn't mean a thing. Get them all to throw at 90% and all of the injuries go away. How you can judge that I don't know.
And we are far from a rec league team. Never confuse fun with mediocrity. We just try our best to avoid burnout in kids that play national level tournament ball 9 months a year. We aren't the best team in the nation, but we can compete with anybody.
