Near disaster - Steve Hansen admits the direct flight five were off their games in Cape Town

Steve Hansen has virtually admitted that sending five players straight to Cape Town could have cost the All Blacks a defeat.

The Springboks nearly completed a stunning reversal, coming agonisingly close to victory against the team which smashed them 57 - 0 at Albany.

The All Black coach said he had "rolled the dice a bit" in an effort to leave more petrol in the squad's tank for the end-of-season northern hemisphere tour.

It almost backfired though. The All Blacks were taken to the wire by the Springboks, with the young outside backs coming to the rescue after the forwards copped a battering.

Sam Whitelock, Sam Cane, Liam Squire, Ryan Crotty and Lima Sopoaga bypassed the test in Buenos Aires. Cane and Sopoaga were noticeably sluggish while Whitelock seemed to fade after a big start.

Hansen indicated at least some of them were off their game in Cape Town.

"Why we did that was not so much for here, but for the end of year( tour)," he said.

"They hadn't played for three weeks, and were probably half a game short. We saw that in their performance - they were a split second off where they are capable of being.

"They felt that themselves, talking to them afterwards. Hopefully we'll get the benefits of doing what we've done somewhere like Cardiff."

* Beauden Barrett's immediate playing future seems unclear, after the All Blacks kept him on the sideline even though he passed a head injury assessment during the test.

"He just felt nauseous and made the comment he had stars," Hansen said.

"If you've been concussed that's one of the symptoms. We felt it was not worth him going back there. He was pretty good today. We've got a couple of weeks and see how we go."

* Hansen confirmed Nehe Milner-Skudder will be out for about six months, requiring an operation after dislocating his shoulder in the Cape Town test.

"He's well versed in what has to come...it's the second one he's done, he had one on the other side," Hansen said.

"He knows he can get the recovery done. He hasn't had much luck, poor bugger.

"But he's playing well and it's a good time of the year for it to happen I guess...he wouldn't have been playing for some of those months."

* The All Blacks will take 37 players on the northern hemisphere tour. There will be no need to take an apprentice this time.

"The last spots are always difficult, we're always open to change, to any mind boggling inspirational thought late in the piece," Hansen said.

* Hansen said South Africa's big men got on a roll early in the Newlands test, and he likened that to trying to deal with that to stopping a barrel rolling down a hill.
"It gets harder and harder to stop," he said.

* He hailed the development of prop Ofa Tu'ungafasi saying he had "grown an arm and a leg" based on improved scrum technique and a belief he now belonged in the All Black environment.

"It's one of the reasons I coach - I love seeing people come into the environment, get better, do things they couldn't before," he said.

"Maybe they didn't believe in themselves, didn't have help."

Hansen said scrum coach Mike Cron had "done extraordinary things with him."
