Of the rest of the backs likely to be included, Aaron Smith, TJ Perenara and Andy Ellis must be considered as front-runners for halfback, Malakai Fekitoa is a midfielder who could play on the wing, with Cory Jane and Ben Smith both comfortable wide out or at fullback. Israel Dagg, in good form for the Crusaders until a calf injury ruled him out of the recent defeat to the Chiefs, is considered a specialist fullback and consistent game-breaker Julian Savea a specialist left wing.
If he is included then it would be a just reward for the 23-year-old Piutau, who is the best-performing back the Blues have got this season.
That might not be much of a compliment given how poorly John Kirwan's attack has been performing, but Piutau's statistics are up there with the best in the competition, most notably in terms of defenders beaten where he is ranked third equal behind Damian de Allende of the Stormers and Waratahs fullback Israel Folau, and alongside in-form Highlanders wing Waisake Naholo.
Piutau is also fourth in terms of ball carries and fifth equal on metres made.
Given the disruption going on ahead of him at the Blues - the struggle to find a consistent halfback-first-five combination and a midfield which has included George Moala, Hamish Northcott, Francis Saili and Pita Ahki, Piutau's continuing good form in a team which has lost eight of their nine games is quite an achievement.
The statistics show Piutau is an explosive runner - and he could yet have the opportunity to show them on the biggest stage.
