Impressing the All Blacks' on-field leader is no doubt a priority for newcomers into the national side - and that was no different for Liam Messam when playing under Richie McCaw in the latter part of the 2000s.
Messam, a long time servant of the Chiefs and Waikato in domestic rugby, made his New Zealand debut in 2008, in the middle of McCaw's reign in the national number seven jersey, and early in his captaincy stint.
The pair enjoyed sustained success in the black jersey with two World Cup wins, five Rugby Championship titles in eight years and continuing New Zealand's ongoing Bledisloe Cup success over the Wallabies.
On top of that, Messam was often part of the world's best loose forward contingent, either as a starting flanker or off the bench.
But as Messam recounts for The XV, there was a not-so-peachy occasion where he and Jerome Kaino elected for a specific colour of boots for a game, which differed from the typical team attire.
