Watched a wee bit of this game. Referee was completely hopeless and seemed totally out of his depth. Constant referrals to TMO.
Now you would think the TMO should get things right but how often in rugby union is the TMO just wrong. Irelland scored a perfectly good try in the second half -the referee despite being just yards away went to the TMO. There were no camera angles showing the ball touching the ground and the TMO and referee between them disallowed the try as neither had seen the grounding.
In rugby league the referee has to signify whether he thinks its a try or not before referral upstairs. The video ref then has to find something to conclusively rule against the referee to change the decision - not two people having a guess at it. Much better system.
