To throw debutant Freddie Burns in from the start could be dangerous because it could go brilliantly but it could also go badly, and against the best team in the world it would be bit unfair to give him a test like that.
He's only 21 and his game management isn't where it's going to be as he matures; he needs a bit more of an education at 10 but once he's got that I think he'll become a good player.
There were positive signs last weekend
England's physicality was impressive last Saturday; they won the battle of the breakdown against South Africa and had the majority of both territory and possession.
England 15-16 South Africa - match highlights
They carried 119 times compared to the Springboks' 68 and made 433m compared to 169m by South Africa - looking at the stats it's a surprise England lost.
But their lack of accuracy proved crucial. England were not great in the line-out, losing five of their throws, and they also turned the ball over 16 times and dropped it eight times.
You can't do against the best teams in the world and expect to win. Repeat that against the All Blacks and they will be in big trouble.
England have to use their heads
England have to be careful how many players they commit to the breakdown on Saturday because when New Zealand defend outside their 22 they don't commit many players, unless they see the opportunity for a turnover.
They wait for one of the opposition to attack in isolation and then they pounce.
Because New Zealand don't commit many to the breakdown they have numbers when the opposition lose possession and their counter-attacks are devastating.
No doubt about the key battle
England captain Chris Robshaw has the biggest task of all because competing with All Blacks skipper Richie McCaw has been difficult for any player over the past 10 years - Robshaw will have to run himself into the ground in order to have an impact.
It's all very well England boss Lancaster talking about the tackles Robshaw has made but the flanker needs effective stats.
Metres run with the ball, turnovers won, those are the kind of stats I would like to see.
Hooker Tom Youngs also needs to play well in the line-out; he can't afford to have a success rate of 64% like he did against the Boks - for this game that rate has to be up in the 90s.
The All Blacks are a precision-tooled machine
Carter has shaken off injury to regain the New Zealand 10 shirt
McCaw is arguably the best player ever to play rugby union, his performances are always excellent.
But individually all the New Zealand players have a high level of skill and technical ability, and as a team they are all tuned into one heartbeat.
