Tend to agree with
@GraemeS for some cases. Slowing the game down is not the silver bullet. If early on players are getting frustrated because you keep stopping the game for small fouls, then that frustration is an early sign. The answer is not to call even more fouls. The key is to understand the issue and figure out a way to mitigate it
for that game. The same solution may not work for every game. You need to use you experience to figure out what works.
For example if dissent has crept in and you suddenly realise you should have handle it much earlier but it is kind of out of control now. It's mainly from one team who is being outplayed. It may be too late but there are a number of possible ways try and regain control but which ones to use totally depends on your personality, your experience, the two specific teams and that specific game. A few ways I can think of, one or more of which you can choose for this scenario.
- slow the game down. Pros: dissent if often caused by by high adrenaline, lowering it could reduce dissent. Cons: players generally want to play. This can bring further frustration especially for the winning team who has been quiet.
- talk to senior players from the losing team. Pros: they may have a level head, take responsibility and work with the team. Cons: it can backfire the senior players put the blame on you with further dissent during the talk. Does your personally and level of experience back up effectiveness of this approach?
I'll make the rest short
- start giving cautions /bin for even small dissent
- give a few more free kicks to to losing team for the small 5-50 fouls
- speed up restarts (less chance to complain at stoppage)
- keeper a distance from hot zones or problem players
- threaten to abandon
There may be a few more but the point is, there is no easy answer.
