Why don't park districts and clubs for u-18's play by the laws that Fifa has set forth? Even high schools don't play by the Fifa laws? Being a major supporter of football around the world it is very frustrating that the US is teaching its younger generation a different set of rules then the rest of the world. Prime examples are substitutions. Fifa states that you may substitute whenever there is a stoppage in play. Most, if not all tournaments I ref have different cicumstances when a team is allowed to sub a player. I was asking a senior official about this and he told me that America has its own way of running the game compared to the rest of the world. It is not good for the game in America to be changing rules that the govering body of football has set forth. Any thoughts on this?
