England are probably the pick of the bunch. They are on average bigger than the French, yet just as mobile. They can scrum, they have ball carriers, they have tacklers, they have lineout men.
The All Blacks will have to work for every inch and they will have to work smarter, more cohesively and more intensely than they did in Paris. They made the point about the pitch cutting up and fingered that as the chief cause of their troubles. Maybe. But All Black coach Steve Hansen is hardly going into the real issues chapter and verse seven days before playing England - one of the best scrummaging sides in the world.
He and his fellow coaches will be scouring the footage to gather as much intelligence as they can about where things might be going wrong. They will already have some ideas.
Changing the personnel is not really an option. There is nothing between Owen Franks and Charlie Faumuina now but the former is better suited to starting. He's not high impact off the bench like Faumuina.
Andrew Hore will most likely come in for Keven Mealamu as part of the old man rotation and be asked to shore things up for 50 minutes.
But it's not going to be a test for shoring things up.
This game is going to need the All Black tight five to be at the peak of their craft.
It's going to need them to be ruthless and intense and blow English bodies away at the breakdown and hit them low and hard in the tackle.
They did that at times in Paris. Sporadic won't be good enough in London.
