You are the leader of the team.  While at games you and your team are representing HOVSA.  It is important to be respectful to the Refs - they always have the final ruling on any calls.  Never argue with a ref or make rude comments to them.  Many are young and doing the best they can.  If you have a legitimate complaint, consider filling out a "Game Incident Report" on the East Central Soccer District website.  This same report can be used for praises and positive feedback.
