Hawk-Eye could revolutionse scrum refereeing
In the draw with Scarlets you could have penalised either side, yet Munster got done for three or four penalties in the scrum.
Hawk-Eye was used at Parc y Scarlets for the first time but it was more to do with the regular calls a TMO would be making.
Maybe it could be used at scrum-time for some of the bigger games - the scrum is such an important part of the game, and when every other facet is so well policed you need to have a better look at the set-piece.
Ex-props or referees could be in a room away from the game deciding on what's right and wrong at scrum-time.
It's impossible for a referee to do it all because they are on one side; you might have the touch judge looking after the other but that still doesn't account for everything.
An overhead view would be ideal, it would give a different perspective and prevent teams from being punished when they are doing very little wrong.
Steve Shingler kicked 18 points from penalties for Scarlets against Munster and a good few of them were on the back of disrupted scrums where it could have gone one way or another.
It really is time for a re-think on reffing the scrum.
