England opener Crawley suggested he had no knowledge of statements from skipper Ben Stokes regarding the dressing room as no place for "those lacking fortitude".
Stokes made this message in multiple conversations in the wake of England's defeat in the second Ashes series against the Australians earlier this month.
Ahead of the Adelaide Test, where the visitors now face a series loss at the earliest opportunity, Stokes noted he had let his sentiment to "drift around" among the squad.
"I've done all the talking in recent days that I required," said Stokes.
But, after the opener scored a knock of 85 on the fourth day in the third Test, he commented: "I missed those remarks."
"I didn't see and wasn't really looking out for it. Our approach is to take anything stated in the media with some skepticism," Crawley continued.
Frank Discussions and Steady Philosophy
Stokes issued his "fragile individuals" observation after his side suffered a loss in the second Test to go 2-0 down.
The England squad afterwards went on a break to a Queensland resort between the second and third Tests.
Prior to this match, he said his team had held "raw" talks and he had asked them to "show a bit of dog" in their effort to stay alive in the Ashes battle.
Nevertheless, Crawley asserted the guidance from Stokes and coach McCullum had stayed consistent with their prior three years in charge.
"It's been very positive, unchanged," noted the opener. "The focus is on maintaining positivity, playing our brand, with great liberty. We believed we were capable of an extraordinary feat going into this Test."
The Hosts On the Verge of Historic Ashes Triumph
The opener's dismissal on day four came during a crucial triple-strike by Australian off-spinner Nathan Lyon.
Lyon's triple strike in 20 deliveries – he also bowled Harry Brook and Stokes himself – left England 207-6 in pursuit of a daunting target of 435.
This means, Australia require four wickets on Sunday's last day to secure an unassailable three-nil lead with three Tests.
Defeat would prolong England's drought in this country to 18 Tests and condemn them to a fourth straight away Ashes series defeat.
This series will be completed in just eleven days of cricket – with England fell the initial matches in rapid time respectively.
The last time 1921, when Australia completed a series win in the UK in eight days, has the destination of the Ashes urn been determined so quickly. The hosts have also triumphed in eleven days on two other instances in the modern era.
"This is disheartening," admitted the batsman. "Our goal was to win the Ashes and we're staring down the barrel at this point."
"There will still be plenty to play for and we will definitely view it with that mindset," he continued.
"The challenge has been tough. Australia is a very, very good side. It was always going to be hard coming here against them. They entered as the front-runners and they've proven why."
Ollie Pope's Place In Question
Although the opener's innings in the third Test probably answers questions about his short-term future in the England team, Pope appears under immense pressure for his position in the Melbourne Test on Boxing Day.
Pope fell for 17 runs in England's second innings on Saturday, adding to his poor record versus Australia.
In 16 Ashes innings, Pope has never made a fifty and boasts an average of just 17.62.
A solitary other English batsman in over a century – Dennis Amiss – has played as many times in the top six in Ashes Tests and recorded a poorer average.
However, the opener said any notion Pope is under the microscope originates with "the media" – meaning the journalists – "and not within the team."
"The squad is fully aware how good of a player he is," said he. "Ollie has enjoyed a productive year if I'm honest."
"He has produced some really good knocks. This is talk externally. There's no discussion like that on Ollie in the camp," Crawley concluded.
