The English opener Crawley suggested he was not familiar with comments made by captain Ben Stokes about the dressing room not being "those lacking fortitude".
Stokes delivered this message in several interviews following his team's loss in the second match of the Ashes versus the Australians earlier this month.
In the lead-up to the third Test, where the visitors now face defeat at the earliest opportunity, Stokes stated he had let his message to "circulate freely" among the squad.
"I have completed the necessary discussions in recent days that I needed to have done," said Stokes.
But, following the opener made 85 on the fourth day in Adelaide, he commented: "I didn't see that."
"I wasn't actively searching for it. Our approach is to take everything that is said in the press with some skepticism," Crawley continued.
Raw Conversations and Steady Philosophy
Stokes made the "fragile individuals" comment after England suffered a loss in Brisbane to fall two matches behind.
The England squad afterwards took a holiday to Noosa between the second and third 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 in contention in the Ashes battle.
Nevertheless, 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 extremely upbeat, unchanged," noted the opener. "It's just trying to be optimistic, playing our brand, with lots of freedom. It felt like we could do something special going into this Test."
Australia On the Verge of Rapid Series Victory
The opener's wicket late on Saturday came during a crucial three-wicket burst by Australia spinner Nathan Lyon.
The spinner's triple strike in a short spell – including the wickets of Brook and Stokes himself – left the chasing side six down for 207 in pursuit of a notional target of 435.
Consequently, Australia require just four more wickets on the final day to move to an insurmountable three-nil advantage after three Tests.
A loss will extend England's winless run in Australia to 18 consecutive matches and condemn them to a fourth successive overseas Ashes loss.
The current battle is set to be decided in just eleven days of cricket – with England losing the initial matches in rapid time each.
The last time 1921, when the Australians completed victory in the UK in eight days, has the outcome of the Ashes urn been determined more swiftly. The hosts have also won in eleven days on two other occasions in the 21st century.
"It's disheartening," admitted the batsman. "We came here to regain the Ashes and now we are facing elimination at this point."
"There will still be plenty to play for and we will definitely view it with that mindset," Crawley added.
"The challenge has been tough. They're a formidable side. It was always going to be tough coming here to face them. They entered as the favourites and they've proven why."
Ollie Pope's Place Under Scrutiny
Although Crawley's performance in Adelaide probably answers questions about his immediate place in the England team, Ollie Pope appears under threat for his spot in the Melbourne Test on Boxing Day.
The Surrey batsman fell for 17 runs in England's second innings on Saturday, adding to his poor record against the old enemy.
In 16 Ashes innings, the Surrey man has never made a half-century and boasts an average of 17.62.
Only one other English batsman in over a century – Amiss – has featured as many times in the top order in the Ashes and recorded a poorer average.
But, Crawley said any notion Pope is being scrutinised comes from "you guys" – meaning the press – "and not within the team."
"We all know how good of a player he is," added he. "Ollie has enjoyed a good year to be frank."
"He has produced some really good knocks. It is noise externally. There is no discussion like that regarding Pope in the camp," Crawley concluded.
