Strength and resources in the back three seem to grow every few months and there are probably a dozen players, including those injured and the unwanted Julian Savea, who would be in front of Tuivasa-Sheck for a place in Japan in two years.
Rugby is tough enough for those with a strong grounding in the game who are then tutored at the highest level and while Tuivasa-Sheck is a superb athlete and a well-grounded bloke, a successful transition to international rugby in one season would be a massive stretch.
His concentration needs to be in full focus tonight at Mt Smart as one of the Kiwis that captain Adam Blair can rely on to lead and help direct play through the inexperienced backline. Like Shaun Johnson, RTS delivers the greatest danger to rivals by running great lines as a support player for others who make a half-break.
If they can get some phase ball, their speed and agility will give fringe defenders plenty of concern and create holes for themselves or space for their Kiwi teammates. Samoa will look to put a clamp on that by taking the game through the middle and pulling the Kiwis into those areas.
The focus for RTS, coach David Kidwell, the Kiwis and anyone who follows rugby league has to be on an opening win at Mt Smart, otherwise conjecture about everyone's future will be in the red zone.
