The English opener Crawley suggested he was not familiar with comments from skipper Ben Stokes regarding the dressing room as no place for "weak men".
Stokes delivered this message in several conversations in the wake of England's defeat in the second Ashes series against Australia earlier this month.
In the lead-up to the third Test, where England are staring at a series loss at the earliest opportunity, Stokes noted he had allowed his message to "circulate freely" among the playing group.
"I've done all the talking over the past two days that I needed to have done," remarked Stokes.
However, after Crawley scored 85 on the fourth day in Adelaide, he commented: "I missed those remarks."
"I didn't see and wasn't really looking out for it. We take everything that is said in the media with some skepticism," he added.
Frank Discussions and Consistent Messaging
Stokes made the "fragile individuals" comment subsequent to his side were beaten in the second Test to fall 2-0 down.
The England squad subsequently went on a break to a Queensland resort between the second and the upcoming Tests.
Prior to the Adelaide contest, Stokes revealed his players had held "honest" talks and he had urged them to "display some fight" in their effort to stay in contention in the Ashes battle.
Yet, the Kent batsman asserted the messaging from the captain and coach McCullum had stayed in line with their prior three years in leadership.
"It's been extremely upbeat, unchanged," said the opener. "The focus is on maintaining positivity, playing our brand, with great liberty. It felt like we could do something special entering this Test."
Australia On the Verge of Rapid Series Victory
Crawley's wicket late on Saturday was part of a crucial three-wicket burst by Australia spinner Nathan Lyon.
The spinner's three wickets in 20 deliveries – he also bowled Brook and Ben Stokes – left England six down for 207 in pursuit of a daunting total of 435 runs.
Consequently, the home team require four wickets on the final day to secure an unassailable three-nil lead with three Tests.
A loss will extend England's drought in this country to 18 Tests and ensure a fourth successive overseas Ashes series defeat.
The current battle is set to be decided in only eleven days of cricket – after England fell the first two Tests in rapid time respectively.
Not since 1921, when the Australians completed victory in the UK in eight days, has the destination of the urn been decided more swiftly. Australia have also won in eleven days on two other occasions in the 21st century.
"This is disappointing," admitted the batsman. "Our goal was to win the Ashes and we're 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 difficult. Australia is a formidable team. It was inevitably tough coming here to face them. They were the favourites coming in to it have demonstrated their quality."
Pope's Position In Question
While Crawley's innings in Adelaide likely secures questions about his short-term future in the side, Pope appears under immense pressure for his position in the fourth Test starting December 26th.
The Surrey batsman fell for 17 in England's second innings on day four, extending his poor record versus Australia.
In sixteen Ashes knocks, Pope has never made a half-century and averages 17.62.
A solitary other England player in over a century – Dennis Amiss – has played an equal number of innings in the top order in the Ashes and recorded a poorer average.
But, Crawley said any notion Pope is being scrutinised originates with "you guys" – meaning the journalists – "not inside the camp."
"We all know how good of a player he is," added Crawley. "Ollie has enjoyed a good year to be frank."
"He has produced some really good knocks. This is talk externally. There's no chat like that regarding Pope amongst the players," Crawley finished.
