Watch: All Black Jordie Barrett scores for Leinster on club debut

Ofc the problem is heightened when the referee has not played in the pack, has never been in a scrum. It is very clear, at least to me, that many top level referees don't begin to understand the mechanics of the scrum.

I feel the laws are adequate as they stand to a great extent. The problem, as I see it, is that referees right up to top level just don't apply them in the the letter of the law or in the spirit they should .

Any significant downward pressure by a prop to cause a collapse should be penalised. For example look at the scrum clip at 54.49 mins. It is the Leinster LH who forces downwards first, then the Munster TH "pancakes" I believe the Leinster prop is the offender there.

I also think that with most of the wheels in those clips, it was Leinster who are the offenders. That can be hard to pick though in many cases. Another point is the hooker standing up. That was being penalised 3/4 years ago. So Kellaher would have been penalised back then in that first clip at 04.17.

I think the directive should be given now to referees at all levels to stop giving penalties simply because a team is being moved backwards. And the directive should be "order the team with the ball to clear it, and within 3 secs."

It would help if a change was made to remove the option to take another scrum after a penalty is awarded. Must take a tap or a kick.

10 bucks says if England, Ireland, France or Wales won a World Cup with a dominant scrum - we wouldn’t be having this discussion.

Barking up the wrong tree there Bull, I didn't like it when Wales did it with Adam Jones in his pomp either!

And the talent drain begins because there's not much enthusiasm playing for Australia. Why would there be ?
