Quote: Conroy "Not really. The RU ref doesn't say whether he thinks it's a try or not he just asks if there is ANYTHING wrong. In other words he has no idea what happened.
The refs in the NRL give their verdict and then ask for something to be checked, EG - I have a try but just double check he grounded it properly or I'm not giving it because he dropped it but just make sure he did.'"
Actually there are two questions asked by RU refs. If the referee has seen the ball grounded but may be unsure about obstruction or a fumble, he asks "Is there any reason that I cannot award the try" which means the TMO does not have to see the grounding.
The second option is to ask. "Try or no Try." Meaning the TMO will have to verify the grounding. In this case if the ball is possibly grounded at the bottom of a ruck but cannot be seen then the try is not awarded.
Seems to me that this method added to the specific questions asked by RL refs would cover most if not all eventualities.
