England opening batter Crawley suggested he had no knowledge of statements made by captain Ben Stokes regarding the dressing room not being "those lacking fortitude".
Stokes made those words in several interviews in the wake of his team's defeat in the second Ashes series against the Australians previously.
In the lead-up to the third Test, where England now face a series loss with a match to spare, the captain stated he had let his message to "circulate freely" within the playing group.
"I have completed the necessary discussions in recent days that I needed to have done," remarked the England leader.
But, after the opener made 85 on the penultimate day in Adelaide, he commented: "I didn't see that."
"I wasn't actively searching for it. Our approach is to take anything stated in the press with some skepticism," he added.
Frank Discussions and Consistent Messaging
The captain issued his "weak men" observation after his side were beaten in Brisbane to fall 2-0 down.
The team subsequently went on a break to a Queensland resort in the gap between the second and the upcoming Tests.
Before this match, he revealed his players had held "honest" conversations and he had urged them to "show a bit of dog" in their effort to remain alive in the Ashes battle.
Nevertheless, Crawley asserted the messaging from Stokes and coach McCullum had remained consistent with their previous three years in charge.
"The atmosphere has been very positive, the same as always," noted the opener. "The focus is just trying to be optimistic, play our way, with great liberty. It felt like we were capable of something special going into this Test."
Australia On the Verge of Historic Ashes Triumph
The opener's dismissal on day four was part of a decisive three-wicket burst by Australia spinner Nathan Lyon.
The spinner's triple strike in a short spell – he also bowled Brook and Stokes himself – meant the chasing side 207-6 chasing a daunting total of 435 runs.
Consequently, the home team require four wickets on Sunday's last day to move to an insurmountable 3-0 lead after three matches played.
A loss will extend England's winless run in Australia to 18 Tests and ensure a fourth successive away Ashes series defeat.
The current battle is set to be decided in just 11 days of cricket – with England fell the initial matches in two and four days respectively.
The last time 1921, when the Australians completed a series win in England in eight days, has the outcome of the Ashes urn been decided more swiftly. The hosts have also triumphed in 11 days on two other occasions in the modern era.
"It's disheartening," said Crawley. "We came here to win the Ashes and we're staring down the barrel now."
"There will still be plenty to play for and we will certainly approach it with that mindset," Crawley added.
"The challenge has been difficult. They're a very, very good side. It was always going to be hard coming here to face them. They were the front-runners coming in to it have demonstrated their quality."
Pope's Position In Question
While the opener's performance in the third Test likely secures questions about his short-term place in the side, Ollie Pope looks under immense pressure for his position in the Melbourne Test on Boxing Day.
Pope was out for 17 runs in the team's second innings on day four, extending his modest returns against the old enemy.
In sixteen Ashes knocks, Pope has failed to score a half-century and boasts an average of 17.62.
Only one other English batsman in over a century – Amiss – has played an equal number of innings in the top six in Ashes Tests and returned a poorer average.
But, the opener said any notion Pope is under the microscope comes from "you guys" – meaning the press – "and not within the team."
"We all know how good of a player he is," said Crawley. "He has had a productive year to be frank."
"He has played several excellent innings. It is noise externally. There is no discussion like that regarding Pope amongst the players," he finished.
