Maxwell does lower the bar in terms of refereeing standards in the NRL.
I didn't see the whole game but one of the worst calls had to be when he said the Tigers had taken their advantage after than Sharks knock-on at the back in the first half. The new rule says that advantage is given on referee discretion. Well, Maxwell's discretion isn't worth much. But it also showed that not all the bad calls went against the Sharks.
But benjis team won so it doesn't matter.
