Despite the fling with hoops, rugby courses through the Whitelocks' veins - from grandfather Nelson Dalzell, who played tests in the 1950s after suffering serious injury during World War II, to siblings George (who played a test at flanker), Luke (an All Black loose forward), and Adam (a former New Zealand sevens player).
Sam, last year's New Zealand Player of the Year, led the Crusaders to their first title in nine years in 2017.
In November, he skippered the All Blacks for the first time - in the end of year test against Wales in Cardiff.
The importance of a balanced life away from rugby is also not lost on the hulking second-rower.
He has completed a degree (in agriculture at Lincoln University), and understands how sport can be an initiator of positive change.
Whitelock was distraught when great mate and All Blacks' logistics manager Kevin "Chalky" Carr died of pancreatic cancer this year.
"Chalky's illness really affected Samuel," Braeden said. "He has always been balanced in his life. He loves his rugby, but when he went to university, he fully participated in university life.
"Now he has a family, he loves spending time with them, and as a result of all of this, he is able to put rugby into a wider perspective."
For Crusaders coach Scott Robertson, Whitelock is the perfect leader and role model.
"He is extremely calm and very clear in delivering his message," Robertson said. "As well, he relates to everyone regardless of their background or experience."
Like Read and Richie McCaw before him, Whitelock is happy to make final decisions but he is inclusive in his style of leadership, as is the modern way.
"He's been great for us," Robertson said. "If he gets the opportunity to again be the All Blacks captain, he certainly won't let anyone down."
