Clip 2 - 12 June 2019 - Law 19
Augustine Pulu, the Blues scrumhalf, puts the ball into a scrum. The Blues hook the ball and it goes back to No.8 Akira Ioane, who picks up and runs. Play goes on.
While the ball is in the scrum, Pulu does not move towards the back of his scrum as the ball does. He stays on the side, backing into the Hurricanes' scrumhalf, Richard Judd, who wants to follow the ball.
Pulu's action makes it easier for Ioane to pick up the ball unharassed.
Law 19:29 Offside at a scrum
Once play in the scrum begins, the scrum-half of the team in possession has at least one foot level with or behind the ball.
It seems that Pulu's right foot tries to stay level with the ball but may well fail to do so throughout.
This is not entirely a nit-pick, as this sort of thing, common enough amongst scrumhalves at scrum time, has the potential to lead to fighting, which is best nipped in the bud by not allowing it to happen. It's at least a management issue.
