For those who think the holdback issue goes away during HS, you couldnt be any further off base. The hold back issue continues through College. if you have nephews or older children just compare how they are at 16/17 to what they are at 21/22 not the same person so yes players continue to mature both mentally and physically. Each year between 16-23 a male continues to grow, maybe not in Height but in things like strength absolutely!
A 19 year old freshman in fall ball is much different that a 17 year old. a 20 year Sophomore is much different than a 18 year freshman. Or better yet a 21 year old Jr is the same as a 21 year old Sr.
Holdbacks and pre-first will continue to have an advantage though college. I have an on age boy, he looks around at the boys a grade younger than him and just laughs, as most played with him when he was younger, some are even older than he is. All great athletes.
