Richie Mo'unga's starring role in the All Blacks' latest comeback victory will inevitably rekindle the debate over who should wear the coveted number 10 jersey.
But perhaps the bigger question was how he ended up kicking the winning conversion in the 32-30 result over South Africa, when starter Beauden Barrett already seemed well in the groove.
Barrett had slotted two penalties in the first half to have his team on level terms 6-6 at the break, after a four-from-four return against Argentina last week.
His goal-kicking had been under intense scrutiny, since his sub-par performance in Wellington three weeks ago cost the All Blacks at least a draw against the Springboks.
"I think [Barrett] was breathing a bit hard and we've got a lot of faith in Richie," observed All Blacks assistant coach Ian Foster afterwards.
"When Richie came on, I think it was more about those two making the decision, a little bit like the week before, when Richie came on and took over the goal-kicking.
"It wasn't a definite strategy, but we trust the decisions they make on the park."
"He banged over a couple of goodies and that's a good experience for Richie."
The other theory offered for the change of kicker was Barrett's decision to fulfil his leadership role after Aaron Smith's try.
"Beaudie, as one of the leaders in the team, saw that as an opportunity for him to get back to halfway and help [captain Kieran Read] manage the group as well," insisted coach Steve Hansen. "That's smart play."
Barrett himself was more circumspect about the delegation of duties.
"We've spoken about it and we've got a plan," he said. "I was feeling pretty good out there, but one thing I've learnt from the Wellington test is you can actually hand the tee over, if you're not feeling good.
"Richie came on tonight with fresh legs and he kicked really well. You might see a bit of that going on."
Barrett was quizzed about how a two-time World Player of the Year was willing to step aside for an international rookie.
"It shows that I've got a lot of faith in Richie," he said. "We have these discussions as kickers and I'm stoked for him that he got the job done tonight."
The first-five debate began during the latter stages of this year's Super Rugby competition, as Mo'unga skilfully steered the Crusaders to a successful title defence.
He came into the national squad probably ranked behind Barrett and utility Damian McKenzie, but has continued to challenge strongly for his opportunities.
Barrett was again not at his best in Pretoria and the All Blacks only came back into the contest after Mo'unga replaced Waisake Naholo, moving Barrett to fullback and Ben Smith to the wing.
"I was saying to myself, 'get through the ball and kick it'," reflected Mo'unga.
"A tendency of mine when I miss is I don't finish the kick and I don't really give it a good nudge. Those are some of the key things.
"It was awesome, it was great. That was every kid's dream to be in that position and credit to the boys that got me there."
