If Richie McCaw ever joins the rugby coaching ranks, it would most likely begin and end at young age group level.
In a Q&A with World Rugby, the former All Blacks captain said although a number of players move into coaching roles after their careers, it wasn't of interest to him.
"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."
McCaw also indicated his frustration with the lengthy delays caused by scrums and suggested a stop-clock should be introduced to avoid the set piece eating away at time on the clock.
