Your 1st example, it’s not cheating according to the rules, but I’d be embarrassed if my kid did that. My dad would have been embarrassed if I did that 40 years ago too. The kids we were impressed with years ago were the kids who played up. Not vice versa. If a kid is held back for academic reasons, social reasons, etc. That’s fine, but that shouldn’t translate to youth lacrosse. Lots of kids like my son play football too. So are you supposed to play on age with one sport, play down with the other? It’s youth sports, play your age.
