England opener Crawley suggested he had no knowledge of statements from captain Ben Stokes regarding the dressing room as no place for "those lacking fortitude".
Stokes made those words in multiple interviews in the wake of England's defeat in the second Ashes series versus the Australians previously.
Ahead of the Adelaide Test, where England are staring at defeat at the earliest opportunity, the captain noted he had allowed his sentiment to "circulate freely" within the squad.
"I have completed all the talking in recent days that I required," remarked Stokes.
But, following the opener made a knock of 85 on the fourth day in the third Test, he commented: "I didn't see that."
"I didn't see and wasn't really looking out for it. We take anything stated in the media with a pinch of salt," Crawley continued.
Raw Conversations and Steady Philosophy
The captain issued his "weak men" observation after his side suffered a loss in the second Test to fall two matches behind.
The England squad subsequently took a break to a Queensland resort between the second and the upcoming Tests.
Before the Adelaide contest, he revealed his team had held "honest" conversations and he had asked them to "display some fight" in their battle to remain in contention in the series.
Yet, the Kent batsman stated the messaging from Stokes and head coach McCullum had stayed in line with their previous three years in leadership.
"It's been very positive, the same as always," said Crawley. "It's just trying to be optimistic, playing our brand, with great liberty. We believed we could do something special entering this game."
The Hosts Close of Historic Ashes Triumph
Crawley's wicket late on Saturday came during a decisive triple-strike by Australian off-spinner Nathan Lyon.
The spinner's triple strike in 20 deliveries – he also bowled Harry Brook and Ben Stokes – meant England six down for 207 chasing a notional target of 435 runs.
This means, Australia need just four more wickets on Sunday's final day to move to an insurmountable three-nil lead after three matches played.
A loss would prolong England's drought in Australia to 18 Tests and ensure a fourth straight away Ashes series loss.
The current battle will be completed in just eleven days of play – with England fell the first two Tests in rapid time respectively.
Not since 1921, when Australia completed a series win in England in eight days, has the outcome of the Ashes urn been decided more swiftly. Australia have also won in eleven days on two other occasions in the 21st century.
"This is disappointing," said the batsman. "Our goal was to regain the Ashes and now we are staring down the barrel at this point."
"There will still be plenty to play for and we'll certainly approach it like that," Crawley added.
"The challenge has been difficult. Australia is a very, very good side. It was inevitably hard touring here against them. They entered as the front-runners coming in to it they've proven why."
Ollie Pope's Place Under Scrutiny
Although the opener's performance in the third Test probably answers doubts about his immediate future in the England team, Pope appears under threat for his position in the Melbourne Test on Boxing Day.
Pope fell for 17 runs in England's second innings on day four, adding to his modest returns against the old enemy.
In 16 Ashes innings, Pope has failed to score a fifty and boasts an average of 17.62.
A solitary other England player in over a century – Amiss – has featured an equal number of innings in the top order in Ashes Tests and returned a lower average.
However, the opener insisted any suggestion his teammate is under the microscope originates with "the media" – referring to the journalists – "not inside the camp."
"The squad is fully aware how good of a player he is," said Crawley. "Ollie has enjoyed a good year if I'm honest."
"He has produced some really good knocks. It is noise externally. There is no chat like that on Ollie amongst the players," Crawley concluded.
