A rugby direction used to be: only the captain should talk to the referee and no one should ever touch the man with the whistle.
Referees were depicted as sole judges and only on rare occasions could a captain approach them to inquire about a decision. Those guidelines have become increasingly blurred.
These days we see clusters of players accosting referees, haranguing them and in some cases physically contacting the officials.
Those cases are nowhere as common or deplorable as the melees which accompany soccer referees around the globe. However there is a noticeable rise in rugby and rugby league players, confronting officials.
Now it's gone to another level with Sharks coach Gary Gold challenging a TMO during a Super rugby match.
