The truth lies in the fact that there's no possible way that thread exists if the Banditos organization did not play winning baseball. They're successfull and will always have a loyal following as long as their success continues. My son has played for the type of coaches that are alluded to in that thread and it didn't work for him. Or maybe I should say that it didn't work for me.
Sports are all about competition and ultimately winning - no matter the level. It's up to each player and parent to chose what's right for them. There's no mold that creates the perfect organization/team and certainly no coaching style or philosophy that can claim to be better than the other. Baseball by definition is a game. Therefore, there should always be an element of enjoyment. Notice I didn't say "fun". Where ever your son finds that "enjoyment", he will stand the most chance to grow as a player.
