A couple of houghts here. First of all soccer teams should have one captain. I am surprised by the army of players that come out to the center circle for the toss and all say "im a captain"
What purpose does a captain serve? The captain is the ONE player a referee MAY choose to direct answers to questions to. There should be almost NO questions anyway at the HS level. They should know the rules. If you allow constant qustioning of calls by players you are digging a hole and not preparing the players for play at a higher level where reffs dont put up with constant dialog.
As far as dissent: how well you want to quash this to maintain game control is up to you. Every statement is different based upon content and context. A player who makes a spontaneous utterance is less affronting to me than one who is obviously trying to show you up. gain an advantage, taunt the opponants, is out of control or brings the game into disrepute needs to be stepped on immediately.
Coaches get even less leeway.
