To be clear you want your freshmen son to play against just 14 year old's. So when HS play rolls around (in 4 months) they should create a special team just for Johnny! It just won't be fair! Fact is there are plenty of age appropriate players that are just bigger and better and parents with less skilled or athletic kids are just looking for an excuse as to why there son isn't as good. They wrongly conclude the kid is older and they are cheating. Maybe it should be a clue that your son isn't a top player. Perhaps he should be playing on B level squads in B level tournaments where he can compete and work on the skills he needs to get better, or until he goes through puberty. Otherwise be happy he is on a top team and gets a chance to work on his play against better players and stop complaining.
