End the speculation. Age verification. I have spoken with several coaches and parents that have verified the left back status of their kids but nothing is done about it. Go to the Yale Fall Bulldog tournament and you will see it on display. Unfortunately it may take a kid getting hurt to change.
This argument has been going on for years in the Long Island and Maryland threads. Bottom line, in high school you play against older kids and in college you play against men. Might as well get used to it now. Makes your son a better player.
The HS kids can still play against older/younger kids- but why not attach a birth year to every player? A coach seeing a small 15 yr old, man handle a big18 yr old fully developed kid gives one food for thought. That smaller 15 yr old sure seems like a good bet if he can handle the older, stronger, bigger player and has yet to go through puberty. Tables turned as well- knowing an older, bigger player repeatedly gets best by kids 1-3 yrs younger gives one something to think about. As long as kids are fighting for a roster spot, and are allowed to play down, age should be connected to their name. Let them play- but also let it be known that they are playing younger opponents. The only people fighting a birthdate being attached or published is those players and their families that have been left back. If you are do proud- might as well flaunt it publicly for all to see!!!
