This guy is totally right. I can see it in my own family. I have two sons 18 months apart one grade apart. Older son is 5'10 140 lbs 14 years old Younger son is 4'8 80 lbs 12 and a half. They would have played on the same middle school team if not for covid. It looks ridiculous. Looks even worse with equipment on. Even worse my older is not the oldest kid on the team. There are 4 kids who are playing down on the school grade cut off, 2 of which that repeated a grade older than him by 6 to 7 months. This has been going on since 1st grade same kids. Even worse there are two kids smaller than my younger one. Its going on in the year below too when my younger kid was in the older grade on a combo some of lower grade kids were the same age or older than him. Parents cheat build up their kids confidence by beating up on younger kids.
