I think that the problem with this thread is that people are looking for absolutes when in fact the truth lies in the center. Refs are confronted with different types of team mentalities from game to game. A stern verbal warning in one game may work just fine, while sending off multiple players may have an aggravating result in another. A couple of weeks ago we were in a game that was very aggressive and the ref warned, and then started sending off players. The players being sent off were high fived by their coach and teammates upon reaching the sidelines. The behavior worsened and remained for the balance of the match. We were short on playing time because of the constant stoppage of play. All in all it was a gross deviations from a normal match, but by no fault of the refs. I think that most refs do their level best to control the game and in most instances their authority is respected, but not in all cases. Some teams are trained to push the level of the laws to the breaking point and prosper by doing so.
