So instead of trying to put your child on a better team, make sure the coach is working toward developing the players and not just searching for the right formula for a winning season. The answer to this question is the true determination of whether your child won or lost this season. PIE stands for Positive, Instructional, and Encouraging. It is a philosophy that we want all to abide by when dealing with players. This means no negative comments towards a player when they make a mistake or fail to perform to your standards.
Referees do have the authority to eject parents, coaches, or spectators who verbally abuse a player.
I see some real bad referees out there. Contact the Regional Referee Administrator and find out when the next referee class is. Then, come to class and become a certified referee. We need people that know the game and can make the calls as they see them. His poor performance may be the result of the lack of understanding of the laws on your part.
