It hasn't taken long. The first Grand Slam since 2003 has England's new coach Eddie Jones confidently predicting his side is now capable of beating the All Black.
Granted, it was a Six Nations competition with no teams ranked higher than fifth in the world but it didn't stop Jones saying bigger scalps would come with time.
"The good thing about it is that there's still a long way to go," Jones said post-match after England beat France at the weekend.
"Winning a grand slam means you're the dominant team in Europe.
"It's a nice first step for us but that's a small step and there are much larger steps to come, starting with the Australian tour.
"Can we beat the All Blacks? Of course we can.
"We can't now but we will in the future. Why else play rugby if you don't think you can beat the All Blacks?".
"The exciting thing for us is we have an average age of 24 and the winning trophy age for Test-match rugby is about 28, so we're three or four years away from peaking."
England's Six Nations triumph is a promoter's dream for Australian rugby officials who now have a blockbuster series on their hands this winter with the bonus of Jones being a former Wallaby coach and going up against former Randwick club mate Michael Chieka.
England play three Tests against Australia and officials say they will sell out after Jones' side captured the Grand Slam.
A Jones-led revival has taken England from embarrassed onlookers in the World Cup finals to Six Nations champions.
Their win over France in Paris clinched their first Grand Slam since 2003.
