Writing in The Guardian, Shaun Edwards believes that some countries gamble unecessarily on new coaching blood.
"Over four seasons you build up partnerships with your fellow coaches as well as the players and Wales were a pretty close unit going off to the World Cup and probably a lot better as coaches when we returned. As a club coach you do learn as you go, but the big infusions in my knowledge have come with the Lions in South Africa two years ago and working with Wales in New Zealand during the World Cup.
"I'd like to think that given the chance, I'd learn a lot more but that doesn't mean I'm angling for anyone's job or negotiating in public. I just think Henry is correct when he says that too many coaches will be losing their jobs because of the result rather than their ability and that some countries gamble unnecessarily on fresh blood when continued learning might be a better course.
"Henry was talking about Martin Johnson, but I'm sure the likes of Declan Kidney, Andy Robinson and Warren Gatland will be better coaches for their southern hemisphere experiences this time around.
"Whereas I'm not sure about the likes of Italy, for example, who seem to be throwing away the collected wisdom of Nick Mallett, rather than asking themselves whether their team came up to expectation or whether Italian rugby would continue to improve under the same management."
