The English opening batter Crawley suggested he was not familiar with comments from captain Ben Stokes about the team environment not being "weak men".
Stokes delivered this message in several interviews following his team's defeat in the second Ashes series against Australia earlier this month.
In the lead-up to the third Test, where the visitors are staring at defeat with a match to spare, the captain noted he had let his message to "drift around" among the squad.
"I have completed the necessary discussions over the past two days that I needed to have done," remarked Stokes.
However, following the opener made a knock of 85 on the penultimate day in the third Test, he stated: "I didn't see that."
"I wasn't actively searching for it. Our approach is to take anything stated in the media with a pinch of salt," he added.
Frank Discussions and Steady Philosophy
The captain made the "fragile individuals" comment after England suffered a loss in the second Test to go 2-0 down.
The team subsequently took a holiday to Noosa between the second and the upcoming Tests.
Prior to this match, he said his team had held "raw" conversations and he had urged them to "display some fight" in their effort to remain in contention in the Ashes battle.
Yet, the Kent batsman asserted the messaging from the captain and coach McCullum had stayed consistent with their prior tenure in charge.
"It's been extremely upbeat, unchanged," said Crawley. "It's just trying to be optimistic, playing our brand, with lots of freedom. We believed we could do an extraordinary feat going into this Test."
The Hosts Close of Rapid Ashes Triumph
Crawley's dismissal on day four came during a crucial triple-strike by Australia spinner Nathan Lyon.
The spinner's three wickets in a short spell – including the wickets of Brook and Stokes himself – meant England six down for 207 in pursuit of a notional target of 435 runs.
This means, Australia need just four more wickets on the final day to move to an insurmountable 3-0 advantage after three Tests.
Defeat will extend England's drought in Australia to 18 consecutive matches and ensure a fourth straight overseas Ashes series loss.
This series will be completed in only 11 days of play – after England fell the first two Tests in two and four days each.
The last time 1921, when the Australians sealed victory in England in eight days, has the outcome of the Ashes urn been determined so quickly. The hosts have also won in eleven days on two other occasions in the modern era.
"This is disheartening," said Crawley. "We came here to win the Ashes and now we are staring down the barrel at this point."
"There will still be significant pride at stake and we will certainly approach it with that mindset," Crawley added.
"It's been tough. They're a very, very good team. It was always going to be tough touring here to face them. They were the favourites and they've proven why."
Pope's Position In Question
While the opener's performance in Adelaide likely secures 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 day four, extending his poor record versus Australia.
In 16 Ashes innings, the Surrey man has failed to score a half-century and averages just 17.62.
A solitary other English batsman since 1900 – Dennis Amiss – has featured an equal number of innings in the top six in Ashes Tests and returned a poorer average.
However, the opener insisted any suggestion his teammate is under the microscope originates with "you guys" – referring to the press – "and not within the team."
"The squad is fully aware of his considerable talent," said he. "He has had a productive year if I'm honest."
"He has produced some really good knocks. It is talk from the outside. There is no chat of that nature regarding Pope in the camp," Crawley concluded.
