The curious nature of the All Blacks Sevens side can be captured by one relationship: 18-year-old Rieko Ioane has spent the last week sharing sevens tips with Sonny Bill Williams, a man who has celebrated almost as many career triumphs as the youngster has birthdays.
The opening day of the Wellington leg of the World Rugby's Sevens World Series saw the hosts' talent-laden squad split into three camps.
The regulars, like captain Tim Mikkelson, provided the glue, the Super Rugby ring-ins, like Williams, added the spark, and those who sat somewhere in between, like Ioane, helped bridge the divide.
It barely matters that he's 18 and has appeared only six times for Auckland - Ioane knows a thing or two about these small-sided games and that, for now, is more than an illustrious team-mate.
"I've helped Sonny out a bit - just getting to know his position when he comes out into the backs," Ioane said.
