The England head coach loathed the label Bazball from its inception, deeming it overly simplistic and perhaps foreseeing how it might be used as a weapon in the future. Currently, down 2-0 in an away Ashes series that started with great expectations, it has turned into the subject of mockery from Australia.
But McCullum has contributed to the problem either. Following the gut-wrenching loss at the Gabba, his insistence that, if anything, England were 'over-prepared' before the pink-ball match was akin to trying to put out a rubbish fire with petrol. It risks becoming his lasting legacy as national coach if results do not improve.
In a way, one must admire his commitment to the bit. As much as McCullum claims to ignore outside criticism, he will have been acutely aware of an England team often described as carefree and underprepared.
The reality, as ever, is not so simple. England enjoy golf just as much during their scheduled breaks as their rivals and they train just as much. Before the Gabba Test, they did more, completing five days to Australia's three, due to their limited experience to the pink Kookaburra ball and the different lighting conditions.
The coach's point about being "excessively ready" was that those five extra days were his call – the instance he blinked in his conviction that minimal preparation is best. It suggested a Test match's worth of focus was expended before they even stepped out in the cauldron of Australia's stronghold. And though nets are a opportunity to refine skills, they can also become a safety blanket; zero consequence work that simply keeps the reactions quick.
Schedules are congested such that warm-up matches against state sides were not possible (with no guarantee, when you consider England playing three before the whitewash in 2013-14). More difficult to justify is the dismissal of county championship cricket as a worthwhile exercise in general, as shown by Jacob Bethell's wasted summer.
Only playing hardens cricketers for the various scenarios they encounter, and it is in this area where England have so far been found lacking. The issue is not just with the bat – as poor as some of the shot selection has been – but an attack that seems leaderless. None has shown the patience or control that the exceptional Australian paceman and his support cast have displayed.
McCullum's unconventional approach was freeing during its first 12 months, an effective, apt remedy to shake off the torpor that preceded it. The frustration now stems from how it has apparently not evolved past that point – the lack of an upgrade to the initial philosophy that has seen results decline to an even record from their most recent matches.
One such player is the wicketkeeper-batter, a gifted player, undoubtedly, but one who is being constantly tested on both edges and has dropped two crucial opportunities as wicketkeeper. It probably does not help when your opposite number, Alex Carey, has just produced a masterful display.
Based on the coach's words in the aftermath, England appear set to keep the faith with Smith in Adelaide. The expectation – as is the case – is that a return to a traditional Test setting triggers his best, with Perth's bouncy pitch and the unfamiliar day-night format now in the past.
Another option is to enact the plan stumbled across during the series win in New Zealand 12 months ago by shifting the batsman down to his more natural home as a active middle order player, giving him the wicketkeeping duties, and selecting a new No 3. Bethell scored runs for the Lions recently, or maybe an all-rounder could fulfil a comparable function to Moeen Ali in 2023.
In the end, these changes is ideal, however Australia's better fundamentals having shattered pre-series optimism and forced the team's entire approach into the harsh glare of scrutiny.
