8. What rules are especially under discussion at the moment?
One current focus of rules development is a trial of what has become known as the "3 up (or out) rule" whereby at least three players of each team must not enter their defending 23 metres area. The aim of this trial is to create more space in this area and therefore to create more flowing and attractive hockey in a key part of the pitch. Indications are that by being less crowded the area will also be safer. Trials at various levels may take place over the next year or so.
Other examples of rules currently under discussion are:
the penalty corner – which is part of the tradition of the game and can be very attractive but about which there are some possibly concerns regarding safety;
the idea of scoring "own goals" in hockey;
further metrication of pitch measurements – including the possibility of changing some dimensions including even the goal and/or circle size … but this would be a very long term proposition if it ever goes ahead at all!
