Wingers coming in a spot have a rather better record (eg. Tana Umaga, Bill Davis) but Piutau looks as if he might have the ability to break the mould. He is strong - strong enough to routinely get past the first tackler or to have his hands free for the offload or the pass. He is a good defender and has a physical presence; he successfully looks for work and enjoys the thrust and parry at this level.
There might be work to do with the subtleties of the centre game. The vision to find a man with a pass can make all the difference and we don't yet know whether Piutau has that. The defensive side of the job is also complex, as Ben Smith is finding; Conrad Smith makes it look so easy with his gliding, instinctive covering, support and accuracy and ability to tidy up.
But Piutau probably made the biggest impact of all the debutants and tyros on display in this so-called "development" test. There would be few definitive judgements able to be made on the back of this match - although Dane Coles and Steven Luatua advanced their cases a little and Tawera Kerr-Barlow did well enough in an important game for him.
Japan is one thing, however, and he will need to show he has that much time and space playing against more major rugby nations to hold off what could yet be a searching challenge from TJ Perenara.
Francis Saili did not have a happy time at second five-eighths and Beauden Barrett demonstrated beautifully that Cory Jane might be a better bet - a much better bet - if the All Blacks are looking for a back-up fullback who is not Ben Smith.
