My son was on the young side for his grade. He gained 25 lbs and grew 2” by the end of his first year at college, bigger, stronger & faster. We didn’t keep him back but wonder what that would’ve done for his confidence if he played with those attributes as a senior in high school? Holding a kid back definitely can make a difference and give one a better chance of being accepted into A more desirable school. Why are Long Island teams so dominant in the early years and then less so in the high school years, Has anyone noticed the correlation between that and the places that reclassify? Regardless whether you like it or not it makes a difference and Most likely benefits the majority of those that do it.
