The All Blacks biggest question marks heading into the Rugby Championship

After a 2-0 series win over England and a resounding victory in America over Fiji, the Scott Robertson era has got off to the perfect start.

The All Blacks have a good segway into the Rugby Championship too, with two games first up at home against Argentina.

While Argentina have tipped two massive upsets in recent years over New Zealand, the All Blacks will be expected to win both ahead of the big tour to South Africa.

Here are the biggest question marks for the All Blacks ahead of the 2024 Rugby Championship campaign.

Halfback worries continue

Halfback remains a challenging position as injuries keep striking. The All Blacks were forced to call up Noah Hotham during the England series, their fifth string No 9.

After one-Test rookie Cortez Ratima went down in the 35th minute, Hotham was required to play big minutes against Fiji. The Crusaders halfback offered some spark, showing a running game that threatened around the ruck and a good tempo.

While Ratima will recover after sitting out the concussion protocols, its safe to say the All Blacks can't afford to lose any more halfbacks.

Ratima and Hotham have impressed, but instability at the position is not good in the medium term as the All Blacks try to embed an attack that can take on the likes of South Africa and France.

They need a starter who can string some games together and get into a rhythm with Damian McKenzie.

Will Jordan is not a straightforward selection at fullback

Expected to have made a full recovery from shoulder surgery by the time the Rugby Championship starts, many expect Will Jordan to slot into the All Blacks at fullback where he played under Robertson at the Crusaders.

For the prolific try scorer with 31 in 30 Tests, it's not so straightforward.

For starters, Jordan hasn't played any rugby this year missing the entire Super Rugby Pacific season with the Crusaders and carries no form into the international calendar.

In Dunedin last year against the Wallabies in his first start in the No 15 jersey, Jordan wasn't convincing. He looked dangerous with ball-in-hand but Test level isn't all about the explosive carries.

The fact is that Beauden Barrett provides better backfield coverage, a more reliable kicking game, better distribution and his standard of play at Test level is higher. Just roll the tape from the last thirty minutes at Eden Park.

You need a fullback who can relieve pressure and Barrett is the best in the country at cleaning up out the back. He kicks off both feet, has good purchase with his punt (something Perofeta struggled with), and the speed is still there. He can diffuse but also sniff out the chance to counter.

It isn't talked about at all but Jordan had his worst game in a black jersey in the World Cup final and that was on the wing. He'll be better for the experience in the long run. The All Blacks can't have that kind of night from their fullback against South Africa, Ireland or France.

Jordan is too good of a player not to be on the park, but his best position at this level is right wing for now.

Backrow needs to find some dominance against Argentina

The backrow was probably one area where England edged the All Blacks across the two Tests.

Ardie Savea is obviously world class but did not have his usual impact in the second Test at Eden Park. He had 11 carries for 9 run metres as England's defence stood up and kept him in check.

There was one trademark power run in the lead up to Mark Tele'a's try, and that was his top play of the night. Two turnovers lost and no turnovers won completed an uncharacteristic night for the superstar No 8.

He rebounded with a great performance against Fiji but nearly everyone looked like a superstar.

Hoskins Sotutu was left out in favour of Wallace Sititi who will be itching to get a run. Against the Pumas, Sititi might get a chance to start.

With South Africa just around the corner, the All Blacks need to find their best combination against Argentina.

That will be tough with Marcos Kremer and Pablo Matera always offering a physical challenge.

Proctor worth another run at No 13

Hurricanes midfielder Billy Proctor's debut was as good as it gets. On a special night in San Diego, Proctor showed what he can offer the All Blacks.

The 25-year-old has been around the scene for some time at Super Rugby level, patiently waiting for his opportunity. Fundamentally a solid defender, Proctor showed an attacking game that was elite in his first run in the black jersey.

His style is different to Ioane and it's worth seeing if he can replicate the San Diego performance against a stronger opponent, which Argentina will be.

Starting with Jordie Barrett in Wellington will be familiar for Proctor, not only is it his home town but obviously the Canes pair have played together a lot over the last few years.

It's worth another look at Proctor as a starter ahead of the trip to South Africa.

The lineout needs to be fixed asap

This is pretty straightforward but the All Blacks set piece cannot continue to malfunction like it did at Eden Park.

Jason Ryan is lucky he's got no hair as he may have pulled it all out by the end of the England series. The communication errors and unforced handling errors were far below an All Black standard.

The loss of Sam Whitelock and Brodie Retallick are proving to be huge, particularly Whitelock, who commands the lineout. An experienced play caller, the All Blacks are missing that right now.

When the lineout is blowing up, the play caller has to get it going, even calling throws at the front if that's what's needed to get some clean ball.

With more time on the turf at NZCIS, the All Blacks surely will get it right for Los Pumas.
