Mtg son is a 2021 and I'm ecstatic! Maybe it'll cut down on the reclassing of kids. There's a BIG difference between 13-14 year olds and 15-16 year olds both physically and mentally.
The top tier schools won't have to speculate as much and early bloomers. won't get the majority of the offers from them.
Plus it's way too early for kids to make such important decisions. They get a couple more years of playing strictly for fun.
