England opening batter Crawley suggested he was not familiar with statements made by captain Ben Stokes regarding the team environment as no place for "weak men".
The all-rounder made those words in several conversations in the wake of his team's loss in the second match of the Ashes series versus the Australians earlier this month.
In the lead-up to the third Test, where England are staring at defeat at the earliest opportunity, the captain stated he had let his message to "drift around" among the squad.
"I have completed the necessary discussions over the past two days that I required," said the England leader.
But, after the opener scored 85 on the fourth day in Adelaide, he stated: "I missed those remarks."
"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
The captain issued his "fragile individuals" observation after England were beaten in the second Test to fall two matches behind.
The team subsequently went on a break to Noosa in the gap between the second and third matches.
Prior to this match, Stokes revealed his team had held "honest" conversations and he had asked them to "display some fight" in their effort to stay alive in the Ashes battle.
Nevertheless, Crawley stated the messaging from the captain and head coach McCullum had stayed in line with their prior tenure in leadership.
"The atmosphere has been very positive, unchanged," said Crawley. "It's on maintaining positivity, playing our brand, with great liberty. It felt like we were capable of an extraordinary feat entering this game."
The Hosts On the Verge of Rapid Ashes Triumph
Crawley's wicket late on Saturday came during a decisive triple-strike by Australian off-spinner Nathan Lyon.
The spinner's three wickets in a short spell – he also bowled Brook and Stokes himself – left the chasing side six down for 207 chasing a notional total of 435 runs.
Consequently, the home team need just four more wickets on the last day to move to an insurmountable three-nil lead with three Tests.
Defeat will extend England's drought in Australia to 18 Tests and condemn them to a fourth straight overseas Ashes series defeat.
This series is set to be decided in only 11 days of cricket – after England losing the first two Tests in rapid time respectively.
Not since 1921, when Australia completed victory in England in eight days, has the destination of the urn been decided so quickly. The hosts have also triumphed in 11 days on two other instances in the modern era.
"This is disappointing," admitted the batsman. "Our goal was to win the Ashes and now we are facing elimination at this point."
"There remains significant pride at stake and we'll definitely view it like that," Crawley added.
"It's been tough. They're a very, very good side. It was inevitably tough coming here to face them. They were the favourites and have demonstrated their quality."
Ollie Pope's Place In Question
While the opener's innings in the third Test probably answers questions about his immediate future in the England team, Ollie Pope looks under immense pressure for his position in the Melbourne Test on Boxing Day.
The Surrey batsman was out for 17 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 boasts an average of just 17.62.
A solitary other English batsman in over a century – Dennis Amiss – has played an equal number of innings in the top order in Ashes Tests and recorded a lower average.
However, Crawley insisted any suggestion his teammate is being scrutinised comes from "you guys" – meaning the journalists – "not inside the camp."
"The squad is fully aware of his considerable talent," said he. "Ollie has enjoyed a productive year if I'm honest."
"He has played some really good knocks. This is noise from the outside. There is no chat of that nature regarding Pope amongst the players," he concluded.
