To be fair it was very dodgy even though his reaction is oot. The ref gave no try for obstruction and the video ref said he could see no real obstruction and sounded like he was going to give it. Then he seemed to have a change of heart and disallowed it.
Now this is where I have the issue, when the ref gives it the video has to show clear proof and in my view there should be try/no try or video ref's call. This year we have seen many trys given and not given where it appeared to be incorrect. How does the ref in real time become a better judge than someone watching in slow mo from all angles?
We also need to clear the obstruction rule up slightly brushing against a defender is not obstruction. Also the high tackle where a player tackles the top of the arm and it bounces up in my view unless there is real dangerous contact they should go back to where the first contact was made. There are far more dangerous cannonball tackles and you can do these if your the first in the tackle and that needs looking at,
