Funnily enough, the All Blacks got nothing but praise for their use of a version of it, with Sonny Bill Williams in the wrecking-ball role, in the first test at Eden Park. What a role reversal.
Now it is the Lions looking to be the creative force. Of course, the pairing of Sexton and Farrell is not a random, gratuitous act.
The combination has played in tandem already by design as well as by circumstance, Sexton coming on early against the Crusaders because of an injury as the Lions impressed in victory over New Zealand's leading Super Rugby franchise, featuring also in the closing stages of the first test.
The dual playmaker role has proven its worth as England have shown with the axis of George Ford and Farrell, the idea being to use their vision and distribution to play the field through their tactical kicking as well as in feeding the outside backs.
Liam Williams's vivid counter-attack at Eden Park that inspired the length-of-the-field try finished by Sean O'Brien was a moment of inspiration (or of desperation) and Gatland clearly wants to bring his strike-runners into the game more often. This is the means to that end.
There is logic underpinning the selection. But there is also risk. And a certain lack of fairness. This is a selection made for the team and not for the individual.
The deposed Ben Te'o has been one of the standout acts in the red jersey, fierce across the gain with devilish intent in his demeanour and some fancy footwork in his feet.
Even though Sonny Bill featured in the first test he did not manage to produce any of those magical, game-shaping offloads that cause such havoc in opposition ranks. Te'o was instrumental in stymieing that.
It is a desperately tough scenario for the 30-year-old. He has made several telling breaks on this trip although the fact that the Lions have not managed to finish off such opportunities might have been held against him.
There is a certain surprise in the decision to retain Alun Wyn Jones after the Wales second-row forward struggled to impose himself last week.
He was blowing hard in the first half although he had taken a knock.
It is obviously felt that his ballast and fighting spirit are what is needed with the putative combination of Courtney Lawes and Maro Itoje considered to be too much of a likeness.
Sam Warburton's return to the colours is a natural course of progression even if the Wales back-rower is on the blindside to allow for O'Brien to continue with his all-consuming performances on the openside.
This is a time for the bugle call to sound. Gatland has rolled the dice. Boom or bust, jackpot or penury? On this selection rests so much.
