Quote ="MorePlaymakersNeeded"Good post. I wondered if Moore could actually see the ball being grounded from where he was stood, which makes me think there should be another option for referees other than try, or no try. He could state that he's not sure and refer it to VR's call, who can then only give a try if they're in absolutely no doubt that a try has been scored.'"
Only Moore will know what he saw or more accurately (pun intended) what he thought he saw. Looking at some of the views on TV review Moore is on the far side of the potential grounding so I don't think he could see anything, I think it was a hunch.
IF there was a signal of Not Sure/No Idea I wonder what it would look like? A simple shrug has that air of 'couldn't care less' and there's enough arm waving from players protesting an infringement, I'd go with I'm a little teapot.
