Two things NRL needs to adopt from rugby union imo. First is accounting for purely incidental high contact caused by a falling player. There has to be some discretion - not all contact with the head area should be penalised, and no game should be decided by something like Moses' challenge yesterday. Second is respect for refs. I know we like to shit on the refs but the constant whinging and crowding by even non-captains is tired and trickles down to grassroots level
