For those of you who have kids involved in team sports - do you find them to be better than their age peers because they are more aware of the way the game works ? My 7 year old loves soccer, has played since he was 4, and is very good (he was just asked to join a new program that is mainly for 9 year olds, ds just turned 7 in June, and is small for his age). I can't decide if he's just really skilled at soccer, or if his knowledge of the game is what makes him so good...?
