Where does it say that they are an A team - as per your standards, Yes its only the 3rd grade please remember that before you try to call out someone about being an embarassment- did your son not make the team or somthing?- what happened to letting the kids play and learn a game. So what if they played in an A or B or Z bracket or in a A or B or Z tournament - all the teams played, had fun and hopefully learned.
