All the blacks, Dan Carter, believe that New Zealand's current side is better than the World Cup winning teams it has been involved in, and that their extraordinary speed has led them to higher heights.
New Zealand, ranked first in the world and fresh from a third consecutive rugby championship title, is preparing for a November test against England on Saturday before traveling to Dublin to face Ireland next week.
36-year-old Carter, three times the world's player during an illustrious flyhalf career for All Blacks, believes the pace of the New Zealand attack will prove decisive against rivals in the Northern Hemisphere at Twickenham.
"The rugby world saw what all blacks from the 2015 World Cup have done when we had a fantastic campaign in England, but I personally feel they have become stronger," Carter told a Tokyo Mastercard Thursday.
"The speed of the game over the last two years has been much faster than other teams.
"But, most of the time, we do not have the chance to come up against the teams in the northern hemisphere … so it's an excellent test for all blacks, just to see where they are.
"I think the speed with which All Blacks is playing the game could be a little too long for England to live with them for 80 minutes."
When Carter surrendered internationally after being named Man of the match in the final victory of the 2015 World Cup against Australia, there were concerns in New Zealand about who would replace the highest score in test history.
However, Beauden Barrett stepped perfectly into boots and already fit with Carter's 24 attempts for All Blacks because of his lightning speed.
"I think what distinguishes him from the other 10 in the whole world is his striking mentality and not just the skills, but above all the speed that he has to create," Carter added his successor.
"The opposition can have all the momentum and puts all the pressure on All Blacks and then a moment of brilliance from a guy like Beaudy who is fast enough to go through goals that many other players can not play, the game ."
