It's been nine years since the Blues travelled south and beat the Crusaders in their backyard. In that time the Crusaders have claimed three Super rugby titles, finished runners-up twice and lost four semifinals.
The Blues' blotchy record has been two semifinal defeats in 2007 and 2011.
The north-south rivalry built on provincial lines, and now franchise selection, remains, but the superiority has tilted regularly towards blokes in the red and black jerseys.
It's been 30 years since a teenage John Kirwan felt that sting and grasped what it all meant. His first lesson was harsh but defining, and now as the Blues coach he is trying to recreate that burn with his 2013 class.
Back in his debut season, Kirwan turned out in Auckland's 31-9 defeat at Lancaster Park.
He put a foot into touch when he thought he had scored and received a great sledge from one of his buddies and later best man, Craig Green.
"He said 'nice try loser' and continued to call me that for a couple of years until we got the Shield two years later," Kirwan recalled. "It was my first sort of test match experience.
"This year the Blues are learning about the intensity of this rugby and the rivalry we have with Canterbury and the Crusaders. Most of them get it and have been competing better.
"It's our responsibility to recreate the rivalry for this to be an epic encounter so the result should be in the balance."
Talk to rival coach Todd Blackadder about the match and you can picture him smiling down the phone.
He has a pack of test forwards, he has a weather forecast which is closing in to favour that crew and he knows where the Blues' problems have been this campaign.
"We'll be ready," is his pithy reply.
The Crusaders lost the opening duel and some of their pride when the Blues smacked them 34-15 at Eden Park. They've been relishing this chance for revenge.
All Black selection is also looming; this is time for the rugby credentials to be evaluated properly.
Similar thoughts have flooded the Blues this week.
If they are going to make the playoffs and be recognised as a strong team as the weather works its way through winter, they have to adapt to different styles of rugby.
All the top sides have a choice of game plans.
The Blues' preference, clearly, is to punch gaps in the game where their lively strike runners can be most effective. They have a stack of them and Blackadder's warm acknowledgment settles on Rene Ranger's work.
He wonders if there is any centre who contributes as much on defence, at the breakdown and with his strikepower, as Ranger.
How the Blues would love the weather to alter as drastically as it did for the New Zealand cricket team on the opening day of the Lord's test.
That is unlikely, so the Blues have been working on balancing that wish with more pragmatic ideas about wet-weather rugby.
They will need to, because this match will be decided by the most switched-on combination.
