In selecting Emilio Gay and James Rew for their Test squad to face New Zealand, England have in one sense been true to their word. The Ashes mea culpa included a promise to give more weight to domestic performances. Both men tick that box.

Yet as the team picks up the pieces after the 4-1 defeat in Australia, wounds licked and lessons learned, perhaps the question is whether they are staying true to themselves more broadly – or even, who actually are they these days?

Asked about his future as head coach at the end of the Ashes tour, and whether he could change his approach, Brendon McCullum gave a notably qualified answer.

“I have a firm conviction in a lot of my methods,” McCullum said. “I’m not against evolution and progress. However, you need to stand for something. Without being ultimately able to steer the ship, maybe there is someone better.”

Among those methods was having a pared-back support staff. McCullum previously felt there were too many voices in the dressing room and duly whipped out the gardening shears. By the time Australia came around it left only two assistants, Marcus Trescothick and Jeetan Patel, and a short-term bowling coach, David Saker.

But when McCullum arrives back in the country next week before a three-day camp in the Midlands – training and team‑bonding before the first Test at Lord’s starts on 4 June – he will walk into a setup that has swelled by way of numbers.

As well as the two assistants, Sarah Taylor will now lead the fielding drills (and no doubt work on fine-tuning Jamie Smith’s wicketkeeping given her own excellence in this regard). Mike Yardy, the England Under-19s head coach, and Will Gidman, who works at Durham, have also been seconded for extra support around the place.

Troy Cooley will attend the camp, having rejoined the English game over the winter as “national pace bowling lead”, while Tim Southee returns as the team’s bowling coach; albeit, like Jofra Archer, only once his work at the Indian Premier League is done. From not wanting too many voices, McCullum now has an entire chorus line.

There is talk that extra coaching input is at the behest of the captain, Ben Stokes. And if so, it strikes to the heart of some of the tension in Australia. McCullum didn’t want players to burn themselves out by over-training, even shoo-ing players out of the nets at times. Stokes, relentless by default, was the one pushing for more.

On top of the extra bodies, England are recruiting a “performance chef consultant” for the team, whose role will be to “plan and execute menus that support training adaptation, match performance and recovery”.

This is in keeping with most modern elite sporting environments. But it also feels very un-McCullum when you consider one of his first moves four years ago was to dispense with the team’s nutritionist. Bacon sandwiches were back on the menu in 2022, with players trusted to make the right decisions.

Another change this summer is the arrival of Marcus North as selector. It looks a sound acquisition, with Durham’s outgoing director of cricket well connected and widely respected in the game. At Chester-le-Street, North is viewed as someone who prefers to give it to players straight but also deals with the human being.

North, like Luke Wright before him, is not the chair of selectors however. As the press release confirming his appointment put it, he will “work collaboratively on selection matters” and “contribute to decisions” regarding contracts. So another voice at Rob Key’s table – an important one – but not calling the shots per se.

In the runs this year for Durham, known to the setup via the Lions, and having made four centuries in Division One last year, Gay is a sound selection as the team’s new opener. How he or any new player adjusts to the step up in standard and scrutiny thereafter is always the great unknown.

But it is not a huge leap to suggest that before the great slapdown Down Under, England may well have opted for the 6ft 7in Ben McKinney, who at 21 is five years younger than his Durham teammate and is considered a terrific prospect. Who knows, they might even have backed Zak Crawley to continue.

As a selector himself, albeit on the other side of the world during the first six rounds of the County Championship, McCullum will have had an input. Likewise regarding the expansion of his backroom staff. The question now is how he fits back into an environment where relaxation is meant to make way for more rigour.

There is also the subject of results. Four years ago McCullum was hired after an Ashes defeat so harrowing that expectations were low – a period that allowed him to breathe fresh life by taking minds away from outcomes. Players were told to be free, to attack, and not to worry about the consequences. It worked well initially.

But this summer, the leadership having survived a rash of missteps in Australia, getting wins on the board against New Zealand and Pakistan feels non-negotiable if this supposed reboot is to have legs. Much may hinge on whether McCullum can adapt, or whether these changes ultimately compromise what he stands for.
