Make no mistake, this was the biggest win for England under Eddie Jones and a real boost in what will be a massive year. What a fantastic performance against the form side in the world and what a fantastic way to kick off 2019.
The Grand Slam in 2016, the 3-0 series win away in Australia, the Six Nations title in 2017 - this trumps the lot and Eddie will be feeling a lot happier.
I can't remember England playing better in his tenure. From one to 15, they were huge and Owen Farrell led the team brilliantly. Flanker Tom Curry had a blinder, despite his first-half yellow card and Jonny May proved he is one of the best wingers in the world.

England head coach Eddie Jones will have left the Aviva Stadium beaming after that display
In a World Cup year this was a real line in the sand. All the rubbish from last year has been consigned to the dustbin, England are on track and Eddie has his mojo back after the distractions of 2018.
Eddie can park all the arguments with club owners - they are producing a roll call of excellent players - and all that peripheral nonsense. Now is not the time to be some sort of pantomime villain in press conferences, now is the time to get busy. England got busy in Dublin.
Ireland had no answer and it has been a while since we have said that. So hats off to Eddie, after a poor 2018, and his defensive coach John Mitchell, to go and win in a place where the All Blacks got seen off in the autumn series.
There were heroes all over the pitch but some of them were in the coaching box. From the start, England exposed Ireland playing Robbie Henshaw who was at full-back with their kicking game and that would have come from the brains' trust.
They also got Manu Tuilagi into the match as soon as they could after his prolonged absences from the Test arena and they took the correct decisions to take the points when they were on offer.
