The England head coach despised the label Bazball the moment it emerged, viewing it as overly simplistic and perhaps anticipating how it might be used as a weapon in the future. Right now, down 2-0 in an away Ashes series that began with high hopes, it has turned into the subject of Australian jokes.
But McCullum has contributed to the problem either. After the crushing defeat at the Gabba, his insistence that, if there was an issue, England were 'too prepared' prior to the day-night Test was like attempting to extinguish a rubbish fire with gasoline. It risks becoming his lasting legacy as England head coach if results do not improve.
On one level, one must admire his commitment to the bit. As much as he says he ignore outside criticism, he will have been acutely aware of an England team often described as carefree and underprepared.
The reality, as always, is more nuanced. England play as much golf during their scheduled breaks as their opponents and they practice equally hard. Before the Gabba Test, they did more, logging five days to Australia's three, due to their limited experience to the pink ball and the different seeing conditions.
The coach's point about being "excessively ready" was that those additional training days were his call – the instance he wavered in his conviction that less is more. It suggested a significant amount of focus was expended before they even took the field in the cauldron of Australia's stronghold. And though nets are a opportunity to iron out technique, they can also become a safety blanket; low-pressure activity that mainly maintains the reactions quick.
Schedules are tight such that warm-up matches against state sides were unavailable (and no guarantee, when you consider England having played three before the 5-0 series loss in 2013-14). What is harder to square is the dismissal of domestic red-ball cricket as a valuable experience in general, as shown by Jacob Bethell's wasted summer.
Match practice alone hardens cricketers for the various scenarios they encounter, and it is here where England have so far been found lacking. The issue is not just with the batting – harrowing as some of the shot selection has been – but an bowling attack that seems leaderless. None has shown the patience or control that the exceptional Mitchell Starc and his support cast have delivered.
The coach's unconventional outlook was freeing during its first 12 months, an excellent, apt solution to eradicate the lethargy that preceded it. The frustration now stems from how it has seemingly not evolved past that initial phase – an absence of an upgrade to the original software that has seen form decline to 14 wins and 14 losses from their most recent matches.
One such player is the wicketkeeper-batter, a talent, undoubtedly, but one who is being constantly tested on each side of the bat and missed two crucial opportunities with the gloves. The situation is not aided when your opposite number, the Australian keeper, has just delivered a virtuoso performance.
Going by McCullum's words in the aftermath, England look likely to persist with Smith in Adelaide. The hope – as is the case – is that a switch to a traditional match environment unleashes his top form, with Perth's bouncy pitch and the unfamiliar day-night format now out of the way.
The alternative is to enact the plan discovered during the series win in New Zealand 12 months ago by moving the batsman down to his preferred position as a busy No. 5 or 6, handing him the wicketkeeping duties, and picking a new No 3. Bethell scored runs for the Lions over the weekend, or maybe an all-rounder could perform a similar role to the former spinner in 2023.
In the end, none of this is ideal, however Australia's better fundamentals having destroyed expectations and pushed the broader philosophy into the spotlight.
