Grant Fox believes that the All Blacks' loss to Ireland last year will make them even tougher to beat at this year's Rugby World Cup.
The All Blacks selector said a tough end-of-year tour in 2018 had further stiffened their resolve as they seek a World Cup three-peat in Japan, and believes that the adversity and challenges they encountered on that tour - most notably in the 16-9 loss in Dublin - will be a useful experience to call upon.
"Ireland was the rock under the beach towel all summer, which just serves as motivation for us. Better to find out how to cope with Ireland, because we've also been beaten by them in Chicago, so they've got a couple over us," Fox admitted to Radio Sport.
"We were making some adjustments to our plan — we aren't going to divulge it but a lot of it worked and some of it didn't so we've made some readjustments. Better to learn that last year than the business end of a World Cup, to take it as a learning experience."
Fox also said he could understand 2011 winning coach Sir Graham Henry saying that he was less confident of RWC success this year, compared to 2015.
