All Blacks legend Richie McCaw has called for a stop-clock to be introduced to end lengthy scrummage delays eating into matches.
The World Cup hero admitted he's frustrated at seeing countless minutes wasted during games for lengthy scrums, which often have to be reset.
At present, the match clock continues to tick along, massively reducing ball in play time throughout a match as officials often talk to the two packs to solve regular issues.
Speaking during a World Rugby Q&A, he said: "One of the things I get a bit frustrated by is the way a scrum can eat up a lot of time in the game.
"If I was going to change something it would be to stop the clock when awarding a scrum and it starts again when the ball comes in. You'd get quite a bit more rugby."
Scrum stoppages and issues around the set-piece have long been a bugbear of many fans.
World Cup referee Nigel Owens recently admitted clamping down on crooked scrum feeds was something current refs need to get better at.
"As referees we always need to be looking at how we can become better referees and when it comes to the force feed, I will put my hands up and say I am one of those referees who could do more," he said.
"We need to address it and at all levels of the game and find a solution. Some of the feeds at the moment aren't even credible.
"Of course we all as referees can always do better, but it's not the referee who collapses the scrum and it becomes the referee's problem if we don't deal with the issues that causes the collapse.
"If we want referees to blow up at every single technical issue then we won't have a game and we'd have 50 or 60 penalties a game."
As for McCaw, he also revealed he has no plans to follow old rival Sam Warburton into coaching.
Warburton has taken on a role under Wayne Pivac's Wales regime, specialising in the contact area where McCaw ruled the world for many years as a player.
"I think I'd just get too frustrated," McCaw said.
"As a player I could get out there and do something about it. But when you are a coach I think you have to have a different way of looking at it. But I'd like to coach young kids one day."
