During the 2014 FIFA World cup we saw the introduction of a white vanishing spray being used by referees to mark where a free kick should be taken.
With rugby referees constantly turning a blind eye to crooked feeds perhaps it is time that they used the same spray to set the scrum. A small line could be drawn as the centre spot with hookers heads positioned over the mark before and when the ball is put in. The mark would also be the line on which the scrum-half must put the ball in. Perhaps this might end the ridiculous feeding by scrum-halves . If referees penalize crooked feeds the No. 9’s would soon learn.
The hookers would then have to hook the ball,which is why they are called “hookers!” Without this basic skill the role of a hooker becomes redundant,as their only designated role would be to throw the ball in at a line-out – which can be done by any player prepared to learn the skill.
