They are paid to do a job, so make the right decisions.
In terms of the Hurricanes 'try' last weekend, both the referee and his assistant had their doubts, believing the ball had gone forward, but they were over-ruled by the TMO. It's doubtful the try would have been awarded had it been the referee's decision.
The on-field officials can see what has happened on the big screen so there's no reason why they can't make the decisions. On Friday night we were constantly told about the size of the screens in Sydney. Well, use them.
More often than not, the TMO is the least capable of the four referees so why are they charged with the important decisions?
By all means consult with the TMO but leave it up to the on-field referee to make the call. They have a better feel for the flow of the game and also a good view of the action as it unfolds.
It's what happens in sevens. A referee asks to see a contentious try on the big screen and then makes a decision, which seems a better way to handle it. Why can't they do the same thing in the 15-man game?
In saying all this, I believe rugby is using technology better than league and I would hate rugby to follow some of the things league has adopted.
League is taking an eternity to play these days because of the number of things referees are checking and I would hate to see multiple TMOs employed for a game like they do with the rugby league bunker.
And putting players on report is a joke. If a referee thinks something is bad enough to put them on report, then have the courage to send them to the sin-bin. The offending side aren't punished in any way if they're allowed to keep their full complement of players.
Rugby isn't too far off getting it right but take all the power away from the TMOs. Please.
