The English opener Crawley suggested he had no knowledge of statements from skipper Ben Stokes about the team environment as no place for "weak men".
Stokes made those words in multiple interviews following England's defeat in the second Ashes against the Australians previously.
In the lead-up to the third Test, where the visitors are staring at defeat at the earliest opportunity, Stokes noted he had let his message to "drift around" among the playing group.
"I've done the necessary discussions over the past two days that I needed to have done," remarked Stokes.
But, after the opener scored 85 on the penultimate day in Adelaide, he commented: "I missed those remarks."
"I wasn't actively searching for it. Our approach is to take everything that is said in the media with a pinch of salt," he added.
Frank Discussions and Steady Philosophy
The captain made the "fragile individuals" observation after his side suffered a loss in the second Test to go 2-0 down.
The England squad afterwards took a holiday to Noosa in the gap between the second and third Tests.
Before the Adelaide contest, Stokes said his players had held "raw" talks and he had urged them to "show a bit of dog" in their effort to remain alive in the series.
Nevertheless, the Kent batsman asserted the guidance from Stokes and coach McCullum had remained consistent with their prior tenure in leadership.
"It's been very positive, the same as always," noted the opener. "The focus is on maintaining positivity, play our way, with great liberty. We believed we were capable of something special entering this game."
The Hosts Close of Rapid Ashes Triumph
Crawley's wicket on day four was part of a decisive three-wicket burst by Australian spinner Nathan Lyon.
The spinner's three wickets in 20 deliveries – including the wickets of Brook and Ben Stokes – meant England six down for 207 in pursuit of a daunting target of 435 runs.
Consequently, the home team need just four more wickets on the last day to secure an unassailable three-nil lead with three matches played.
A loss will extend England's drought in Australia to 18 Tests and ensure a fourth straight overseas Ashes series defeat.
This series is set to be decided in only 11 days of play – after England losing the initial matches in two and four days respectively.
Not since 1921, when Australia sealed victory in the UK in eight days, has the destination of the urn been decided more swiftly. The hosts have also won in eleven days on two other instances in the modern era.
"It's disappointing," admitted the batsman. "Our goal was to win the Ashes and we're facing elimination now."
"There will still be significant pride at stake and we'll definitely view it like that," Crawley added.
"It's been difficult. They're a very, very good team. It was inevitably hard coming here against them. They entered as the front-runners coming in to it they've proven why."
Ollie Pope's Position Under Scrutiny
Although the opener's innings in the third Test likely secures doubts about his immediate future in the side, Pope looks under immense pressure for his spot in the fourth Test on Boxing Day.
The Surrey batsman fell for 17 runs in England's second innings on day four, extending his modest returns versus Australia.
Across 16 Ashes innings, the Surrey man has never made a half-century and averages 17.62.
A solitary other England player in over a century – Dennis Amiss – has played an equal number of innings in the top six in the Ashes and returned a poorer average.
But, Crawley insisted any notion his teammate is being scrutinised originates with "the media" – referring to the journalists – "not inside the camp."
"The squad is fully aware how good of a player he is," added he. "He has had a good year to be frank."
"He has played several excellent innings. This is noise externally. There is no chat like that on Ollie in the camp," Crawley concluded.
