"My old mate Dan Carter there's no doubt he must've been pretty close. I was lucky in my time playing for the All Blacks having a guy like that as a number 10 who directs things ... pretty lucky to have him in my team which helped for a lot of success.
"I think you could've made an argument for all those All Blacks guys – Beauden [Barrett] and Kieran Read and Brodie Retallick. I played alongside all those fellas and they're all worthy winners of those awards each of those years.
"It's quite hard to pick who was better or what. It's all a bit subjective isn't it. But I think always when you get an award like this, you realise you can't get it without having a good bunch of people around you."
McCaw led the All Blacks to two World Cup triumphs in the decade and was named player of the year in 2010. He retired at the end of the 2015 World Cup.
He played 68 of his 148 test matches for the All Blacks between 2010 and 2019 – he was captain for all but one, against Namibia at the 2015 Rugby World Cup – with a record of 61 wins, two draws and five losses.
McCaw also made the team of the decade alongside All Blacks Ben Smith, Ma'a Nonu, Carter, Retallick, Sam Whitelock and Owen Franks.
