Scott Sio is the son of Samoan prop Tavita ‘David’ Sio and has a first name steeped in rugby history. His dad was a member of the famous, giant-killing Samoan XV who upset Wales, almost beat Australia and ultimately made a shock 1991 Rugby World Cup quarter-final appearance. Back at home in Sydney, mum Tina gave birth to a baby boy in the week before Samoa played Scotland in Edinburgh. That was shortened to Scott, and 21 years later, young Sio, playing for the Brumbies in Super Rugby, emulated his dad by winning a first Test cap, against New Zealand in Sydney.
