Conversation is about little kids, if he is at a D1 program now, that means he wasn’t an 8,9 year old kid for about 10,11 years. Was it grade based back then? Probably not. Even though your post is probably not true, that’s not the point. The point is those parents chose to let their older kid play against kids a year or 2 younger. Normal people would be embarrassed doing this for Youth sports. Any sport. If my 10 year old son ran for 300 yards, scored 4 touchdowns against 8 and 9 year olds I’d be embarrassed. If my 10 year old threw a no hitter against 8 and 9 year olds I’d be embarrassed. If my 10 year old had 40 points and 20 rebounds, against 8 and 9 year olds I’d be embarrassed. So you say how wonderful those parents were, not in my book. Wonderful is doing things the right way.
