 However, this implies that these players must play in the defence should the opposing team be able to switch quickly to offence.The latter is another benefit for fast playing teams.If the attacking team does not make sufficient progress (eventually releasing a shot on goal), the referees can call passive play (since about 1995, the referee gives a passive warning some time before the actual call by holding one hand up in the air, signalling that the attacking team should release a shot soon), turning control over to the other team.
