Both Wyatt Crockett and Ben Franks will feel more could have been done to squeeze the Japanese scrum in the first half.
Tawera Kerr-Barlow didn't kick well enough from the base. Francis Saili, a wildly talented footballer, let his propensity to try too much run away a bit. He's at his best when he hits the ball, shoulders square, hard and direct. Too often he was drifting. Beauden Barrett had all of his usual willingness and eagerness, but there was some poor execution. A missed touch finder from a penalty and a miscue off the side of his boot tainted what was an otherwise solid afternoon.
Cane was accurate and relentless again but he has of course the not insignificant issue of playing in the same position as the skipper.
Piutau is likely to be the only man with genuine cause to wonder whether he might have forced a change of thinking about the line-up for France.
He was the star of the show: so alive to opportunity, focused, powerful, sharp and constructive. His two tries were just rewards for his work-rate and contribution, even if he was steadfastly refusing to be carried away with his performance.
"It was about ticking off the roles in my job," he said. "It is about making sure that when I get an opportunity, I make the most of it. Whatever the coaches are telling me to do in the week, I try to do that to the best of my ability.
"On the wing it is about connecting with the centre defensively. It was about making my connection with the back three, being able to work together, finish off, carrying strong and kick-chase - making sure I contest.
"It was quite a slow start. We didn't want to get drawn into throwing the ball around but it kind of did happen like that. We didn't get into our structures as well as we wanted to. I guess, there is a lot we can work on."
As well as Piutau played, Cory Jane is in chronic need of game time, having managed only 120 minutes of rugby all year because of injury. The veteran is likely to start in Paris but after that - the decision between him or Piutau could be decided on form.
