The English opener Crawley has indicated he was not familiar with statements from skipper Ben Stokes about the dressing room as no place for "those lacking fortitude".
Stokes made this message in multiple interviews in the wake of his team's loss in the second Ashes series against the Australians previously.
Ahead of the third Test, where the visitors now face defeat at the earliest opportunity, Stokes stated he had let his sentiment to "drift around" among the playing group.
"I've done all the talking over the past two days that I required," said Stokes.
However, after Crawley scored a knock of 85 on the fourth day in the third Test, 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 media with some skepticism," Crawley continued.
Frank Discussions and Consistent Messaging
The captain made the "fragile individuals" observation after England were beaten in Brisbane to fall 2-0 down.
The team afterwards took a break to Noosa in the gap between the second and the upcoming Tests.
Prior to this match, Stokes revealed his team had held "honest" conversations and he had urged them to "show a bit of dog" in their effort to stay in contention in the series.
Yet, the Kent batsman stated the messaging from Stokes and coach McCullum had remained consistent with their prior three years in leadership.
"The atmosphere has been very positive, unchanged," said the opener. "It's on maintaining positivity, play our way, with great liberty. We believed we could do something special entering this Test."
The Hosts Close of Rapid Ashes Triumph
The opener's wicket on day four was part of a decisive three-wicket burst by Australia spinner Nathan Lyon.
Lyon's three wickets in a short spell – he also bowled Brook and Stokes himself – left England six down for 207 in pursuit of a notional total of 435.
This means, Australia require just four more wickets on Sunday's final day to move to an unassailable 3-0 advantage after three Tests.
Defeat would prolong England's drought in Australia to 18 consecutive matches and condemn them to a fourth straight away Ashes series defeat.
This series is set to be decided in just eleven days of play – after England losing the initial matches in rapid time respectively.
The last time 1921, when Australia sealed victory in the UK in eight days, has the outcome of the Ashes urn been decided so quickly. The hosts have also triumphed in eleven days on two other instances in the 21st century.
"This is disheartening," said Crawley. "We came here to win the Ashes and now we are facing elimination at this point."
"There remains significant pride at stake and we will definitely view it like that," Crawley added.
"The challenge has been tough. Australia is a very, very good team. It was always going to be hard coming here against them. They were the front-runners coming in to it have demonstrated their quality."
Ollie Pope's Position Under Scrutiny
Although Crawley's performance in the third Test probably answers questions about his short-term future in the England team, Ollie Pope appears under threat for his position in the Melbourne Test on Boxing Day.
Pope was out for 17 in the team's second knock on day four, extending his poor record versus Australia.
In 16 Ashes innings, Pope has never made a fifty and averages 17.62.
A solitary other England player since 1900 – Amiss – has played an equal number of innings in the top six in Ashes Tests and recorded a lower average.
However, Crawley insisted any suggestion his teammate is being scrutinised originates with "the media" – meaning the press – "not inside the camp."
"The squad is fully aware how good of a player he is," added Crawley. "Ollie has enjoyed a productive year if I'm honest."
"He has played some really good knocks. It is noise externally. There's no chat like that regarding Pope in the camp," he concluded.
