It is two years since Martin Johnson took what we thought was an emerging England rugby team to Ireland to win a Grand Slam - and got absolutely trounced.
But if you want to read any significance into that piece of history as another Red Rose side goes in search of a Slam at the Millenium Stadium on Saturday, just take a look at the team sheet. It's a measure of just how quickly Stuart Lancaster has torn up everything from the regime he inherited that just FOUR of that defeated Dublin team are likely to start in Cardiff.
Chris Ashton, Dan Cole, James Haskell and Tom Wood are the survivors - with Toby Flood the only other who could possibly be involved although he's far more likely to be on the bench to make way for the return of the dynamic Owen Farrell.
The lack of mental strength that was exposed under pressure that day came back to haunt England in the World Cup, and actually did Lancaster a favour because it gave him the perfect opportunity to begin his revolution. New Zealand had seen a low in terms of performance and behaviour, and both public and players were ready to draw a line under it all and start again.
Since then the team has been driven by a culture of continuous improvement. I picked out back in January the attention to detail as the reason to back an England Grand Slam when the price was as high as 7.06/1, and by now they will be even better equipped to handle the Millenium Stadium atmosphere. After all they set up this Grand Slam campaign in the second game by returning to Dublin and winning, and you sense a mood of determination will be hardened further when the team bus rumbles across the Severn Bridge.
The decision to rest Farrell from last weekend's win over Italy underlined just how central the young fly half has become - not just for his metronome kicking but for his ability to make the right choices of how to launch attacks. Without him England became pedestrian. Don't forget it was Farrell who was the star of the show when England recorded their best result so far under Lancaster - beating the All Blacks last Autumn - and he is the man who will most relish the big occasion again.
It won't be easy - making the most obvious bet in the early markets not the 1.8810/11 for an England win but up to 3.052/1 for Lancaster's side to win by under 12.5 points. But it will be significant that while Farrell returns for England, Wales have learned they will be without their own leader after captain Ryan Jones was ruled out with a cracked shoulder bone.
Curiously coach Rob Howley won't name who will take over as skipper until tomorrow, rather than simply restoring Sam Warburton to the role. That's an odd decision to allow a bit of uncertainty to creep in. The key to Saturday's game will be who best handles the occasion in the first 20 minutes, and you would think that allowing any doubt around his selections would weaken Wales.
Their record at the Millenium this season reads played five, lost five. So while England couldn't handle the atmosphere in Dublin two years ago, this squad will know only too well that this time it is the home team who will be under most pressure if they can keep it tight.
