This was pulled from a discussion in a different forum.
I see this a lot with kids who have had more instruction than the regular Little Leaguers who just play during the regular LL season. It is something I am also curious about.
Is this just what kids look like with adult level mechanical instruction? Are there musculatures just undeveloped and this is how is presents?
To me this looks like the mechanical arm of an older pitching machine. I have coaching responsibilities for very young throwers and see the stronger/better athletes do not look like that at this point.
