In a nutshell, the IRB’s new scrumming laws will be tested for a trial period.
“Pause!” will disappear altogether.
“Engage!” will be replaced by “Set!”
So it will be “Crouch! Touch! Set!”
So as soon as the props withdraw their arms after touching the opposing prop’s outside shoulder, the ref will call “SET!” when the front rows are ready.
The IRB expert steering committee did however state that “there is no quick and easy fix. There are many contributing factors and we need to take a complete view of the scrum environment including engagement, Laws, forces and player welfare.”
Testing showed that “Crouch! Touch! Set!” was the most successful approach and will now be trialled globally.
It will be interesting to see how this one pans out.
