The emasculation of Irish rugby began at 4.45pm on Saturday, February 2, 2019 and lasted 91 seconds. In that short space of time, a ferocious England opening knocked Joe Schmidt's team off their perch. Eddie Jones' men finished the job, backed it up in August with a record win and then did the same to Andy Farrell's charges at Twickenham last February.
With Saracens continuing the theme in their meetings with Irish opposition, the balance of power has remained favourable to England and they are intent on keeping it that way when Ireland run out in London tomorrow.
In each of the matches, England have outmuscled the Irish pack and outthought their backs. Although Ireland scrummaged well in the Dublin game, their set-piece has creaked since. They've wilted in contact and lost the breakdown.
Schmidt said the 30-22 defeat at the start of the Six Nations campaign had seen his side "bullied" and warned that they had laid down a marker for the levels needed to perform in Japan.
No team did more to undermine the success Ireland enjoyed under Schmidt than Jones' England. As it stands, they're superior in all the key facets.
The 'Dominant Tackle' statistic wasn't widely available before that Aviva Stadium game, but England's 30 to Ireland's 7 summed up the day. In the two matches since, England have consistently won the gainline battle on both sides of the ball.
When Ireland have it, England suffocate them and turn them down blind alleys. When England have it, they create momentum and the Irish defence folds in to create space for the speed merchants on the edges.
England have huge, fit, powerful, skilful players across the park, although the loss of Manu Tuilagi does remove a major thorn from the Irish side.
Farrell has picked a big team, but as Jones said yesterday: "The challenge is can they bring a dominant Irish performance to Twickenham?"
In the last three games, England have been more aggressive on and off the ball and, while Ireland tried to fight back last time out, they couldn't rattle Maro Itoje and co.
It begins in the tackle and continues at the breakdown. If England win the collisions again, Ireland are in trouble.
In 2017, Jones goaded Ireland and the Aviva Stadium crowd by describing Schmidt's tactics as "kick and clap" rugby.
Nowadays, his team put boot to ball more than anyone else in the game and they do it better than anyone else, getting tries directly from their chips in recent meetings.
Hugo Keenan is the fourth different full-back to start against England in these fixtures. The Leinster man needs all his game-intelligence to read Ben Youngs and Owen Farrell's intentions and cover the ground, with Keith Earls and James Lowe needing to support him.
According to Jones, however, it's all about how things go in front of them.
"You're only able to attack the backfield when you are able to get through the front line," he said.
Ireland's scrum kept them in the game in Dublin, but recent events at the same venue will be causing Andy Farrell some concern.
Five of the six starters tomorrow played when Leinster lost their Champions Cup quarter-final to Saracens and, crucially, referee Pascal Gauzere was in the middle as he whistled Cian Healy, Ronan Kelleher and Andrew Porter off the park.
Jones wasn't long in stirring the pot yesterday as he suggested there are irregularities in the young Irish tighthead's technique, saying "Porter scrums in a fairly unusual way, which may need some referee intervention there".
If the scrum goes against the visitors, it will be the longest of afternoons as England look to launch Billy Vunipola at every opportunity.
Considering the vast majority of Ireland's scores come off their lineout, it is essential that Ronan Kelleher finds his men.
The work doesn't stop there. Once on the deck, England will look to destroy Ireland's maul in the same way France did in Paris.
In 2017, Peter O'Mahony made life hell for Dylan Hartley in Dublin as Ireland denied England a Grand Slam.
If they can deny them that access into the game, it'll be a positive starting point.
Cohesion is important at this level of the game and England have it in spades.
In the last three meetings, Ireland had long-standing partnerships all over the park, but tomorrow every department is in its formative stage at this level.
