Test rugby returns to Aotearoa this weekend with the All Blacks taking on the Wallabies in the first Bledisloe Cup test in Wellington.
Centurion Lock Sam Whitelock will no doubt be selected to start, he has played for the All Blacks since 2010, appearing in 117 tests, even captaining a few.
The bearded second rower has been a mainstay in the All Blacks engine room for a decade and has been to three World Cups, winning two.
He has been coached in the national side by Sir Graham Henry, Sir Steve Hansen and now Ian Foster, who will mark his first test as coach in Sunday's Bledisloe opener.
So, what differences has Whitelock noticed in the leadership styles of those three men and between new captain Sam Cane and former skipper Kieran Read.
