Correct. That's US lacrosse cutoff. I Believe, U9, U10 etc is your age on 8/31. I may be wrong, but that's what I read.
But Warrior games you since up specifically by graduation year. Twist it anyway you want. If you sign up for 2025 that is the HS graduation year not age. Drop the topic and do whatever you decide to do and stop looking for someone to tell you what's right. Bottom line a boy with a fall birthday will have a tough time. Not saying it is fair but then leave him back if that's what you want to do. Otherwise play his year.
