1. Stop coaching
This might be the toughest, given how ingrained it has become, but it is also, paradoxically, one of the easiest. Referees need to communicate less. If a player is offside from chasing a kick, don’t tell them to get back, penalise them! If a player is offside at a ruck, don’t tell them to retreat, penalise them! If a player is deemed as off their feet at a ruck and continues to contest for the ball, don’t tell them, penalise them! They will not do it again. Discipline would improve tenfold, with players no longer willing to push the laws to the absolute limit – and beyond.
The auxiliary benefit, too, would be that non-English-speaking teams would benefit, given they are palpably hampered every time they take the field with an English-speaking referee. Referees should speak with their whistle and little else.
