What is it about Leinster assistant coach Richie Murphy that everyone wants to keep working with him?
The former fly-half has been a central member of the Leinster coaching ticket for more than five years.
He has listened to and learned from Michael Cheika, Joe Schmidt and Matt O'Connor, while making an increasing impact as a tactician to what Leinster do week-to-week.
Murphy is more than a Skills and Kicking coach. The time is coming when he will be a serious candidate to move into the hot seat at Leinster or somewhere further afield.
"I would definitely like to move on in the future to try to become a head coach," he said.
He signed a new two-year deal for the province in the summer, indicating head coach Matt O'Connor's satisfaction with his contribution to the overall flavour of the province.
More importantly, Schmidt's choice to bring Murphy to Ireland, not just in a Mark Tainton-type specialist role, reflects on the 'added value' Schmidt sees in him.
"That is one of the reasons why I wanted to do Leinster and Ireland, the fact that I would get that hands-on experience on a daily basis," said Murphy.
"I am very comfortable in what I am doing at the moment. I feel I understand what the two head coaches are looking for within the two groups I am working with and that I can give them the support they need.
"Working with two coaches like Joe and Matt - and Michael Cheika beforehand - gives me great experience on how they deal with different situations."
In Munster, Anthony Foley has taken over from Rob Penney. At Ulster, Ireland defence coach Les Kiss has been employed to follow Mark Anscombe.
"Obviously, I am delighted to be given the opportunity by Leinster and Ireland to work with them again," said Murphy.
"It is going to be a case of making sure that I am able to apply myself properly to both jobs.
"My role over the last couple of years has grown quite a lot. Matt and Joe, both of them, will listen to stuff that I bring to the table and a lot of that gets applied on a weekly basis."
