Though we did not know it at the time, that was the beginning of England’s Bazball journey. Legend has it how, by degrees, the fates of England and McCullum would entwine and interlock: first, through his close personal friendship with his counterpart Eoin Morgan, who would adopt and adapt his mentor’s aggressive methods to glorious effect for the 2019 World Cup, and then, in 2022, with the relaunch of the Test team under McCullum and Ben Stokes – essentially a transfusion of that new unfettered attitude from white ball to red.

Lest it be forgotten amid the navel-gazing, Buttler did achieve that aim magnificently at the first time of asking. And yet, even as he piloted England to the T20 World Cup in 2022, there were doubts as to whether he had placed his own stamp on the team that Morgan rebuilt, or simply pressed the right buttons and got the requisite response from men that he had already gone the journey with: Stokes and Adil Rashid chief among them.

These doubts were redoubled in 2023, when England’s bid to get the 2019 band back together came such a spectacular cropper at the 50-over World Cup in India. And since then, even though McCullum’s arrival as all-formats head coach implies a renewed focus on white-ball cricket, this winter’s Ashes is surely the more pressing reason for the realignment. Irrespective of the setbacks in the short term, the consistency of messaging to the likes of Harry Brook, Jamie Smith and Ben Duckett, not to mention England’s cohort of hard-worked fast bowlers, could yet be crucial in a legacy-defining campaign.

“There have been few players of Buttler’s generation whose performances have seemed so dependent on his mood. His famous bat-handle message has long been a prop to remind him to snap out of it, but his innate pessimism was even in evidence in the Afghanistan defeat”

By the time of his ODI debut in February 2012, Buttler was already a star of the county one-day scene, having amassed 854 runs at 71.17 in his first two seasons with Somerset, including two Lord’s finals. In an early example of the ECB’s fretting about attention spans, the format back then was 40-overs not 50, and yet, as Matt Roller and Tim Wigmore noted in White Hot, their book about England’s white-ball renaissance, this had the unexpected benefit of drawing out the players’ aggressive tendencies, but not at the expense of technique and endurance.

By contrast, the advent of the Hundred has taken all such long-haul considerations out of the picture, and with it the very best players. Brook, Buttler’s heir apparent, had not played a single List A game since May 2019 until his ODI debut against South Africa in 2023, and while Smith averaged 63.00 in Surrey’s run to the One-Day Cup semi-final in 2021, his elevation to Hundred marquee status means he may never again feature in a competition that ticks over as a county development project in those overshadowed summer weeks.

It’s hard, then, to blame Buttler if he has struggled to greet the advent of “white-ball Bazball” with anything like the same enthusiasm and optimism that Stokes dredged up for the red-ball project. There’s next to no reason for a player who has achieved as much as he has, and with such a stellar cast alongside him, to believe that the best really is yet to come. Of his 2019 team-mates, only Rashid is performing at anything like the requisite level, and he is already 37. Buttler himself has made three fifties in 15 innings across formats since November, having missed five months with a calf injury.

If Buttler, of all people, could not be persuaded to suspend his disbelief at the outset of this alliance, then who realistically could fill such a void? Ten years on from that tide-turning loss, this time England’s standards may simply have sunk with their skipper.
