England opening batter Crawley suggested he had no knowledge of comments from captain Ben Stokes about the dressing room not being "those lacking fortitude".
Stokes made those words in several interviews following England's loss in the second Ashes series against the Australians previously.
In the lead-up to the third Test, where England are staring at defeat at the earliest opportunity, Stokes noted he had allowed his message to "drift around" within the playing group.
"I have completed all the talking in recent days that I required," remarked the England leader.
But, following the opener made a knock of 85 on the penultimate 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 everything that is said in the media with some skepticism," Crawley continued.
Raw Conversations and Steady Philosophy
Stokes issued his "fragile individuals" comment after England suffered a loss in the second Test to go two matches behind.
The team afterwards took a break to a Queensland resort between the second and the upcoming Tests.
Before the Adelaide contest, Stokes revealed his team had held "honest" conversations and he had urged them to "display some fight" in their effort to remain in contention in the series.
Nevertheless, the Kent batsman stated the guidance from Stokes and head coach McCullum had remained in line with their prior three years in charge.
"The atmosphere has been extremely upbeat, unchanged," noted the opener. "It's just trying to be optimistic, play our way, with lots of freedom. We believed we were capable of something special going into this game."
Australia Close of Historic Series Victory
Crawley's wicket late on Saturday came during a decisive three-wicket burst by Australia spinner Lyon.
Lyon's triple strike in a short spell – he also bowled Brook and Stokes himself – left England 207-6 in pursuit of a daunting target of 435 runs.
This means, Australia require four wickets on Sunday's last day to secure an unassailable 3-0 lead after three Tests.
Defeat will extend England's drought in Australia to 18 consecutive matches and ensure a fourth successive away Ashes loss.
This series will be completed in only eleven days of play – with England fell the first two Tests in rapid time each.
The last time 1921, when the Australians completed a series win in the UK in eight days, has the outcome of the Ashes urn been determined more swiftly. Australia have also triumphed in eleven days on two other occasions in the 21st century.
"This is disappointing," admitted Crawley. "We came here to win the Ashes and we're staring down the barrel now."
"There remains significant pride at stake and we'll certainly approach it with that mindset," Crawley added.
"The challenge has been tough. They're a formidable team. It was always going to be tough coming here against them. They were the favourites coming in to it have demonstrated their quality."
Ollie Pope's Position Under Scrutiny
While Crawley's innings in Adelaide probably answers doubts about his short-term place in the side, Ollie Pope appears under threat for his position in the Melbourne Test on Boxing Day.
The Surrey batsman was out for 17 runs in England's second knock on Saturday, adding to his modest returns versus the old enemy.
Across 16 Ashes innings, the Surrey man has never made a half-century and averages 17.62.
Only one other England player since 1900 – Amiss – has played as many times in the top order in the Ashes and returned a poorer average.
But, Crawley said any notion Pope is under the microscope originates with "the media" – referring to the journalists – "and not within the team."
"The squad is fully aware of his considerable talent," added he. "He has had a productive year if I'm honest."
"He has produced several excellent innings. It is talk externally. There is no discussion of that nature regarding Pope amongst the players," he finished.
