England opening batter Crawley suggested he was not familiar with comments made by skipper Ben Stokes about the dressing room as no place for "those lacking fortitude".
Stokes made those words in several interviews in the wake of England's loss in the second match of the Ashes against the Australians earlier this month.
In the lead-up to the Adelaide Test, where the visitors are staring at defeat at the earliest opportunity, Stokes noted he had allowed his sentiment to "drift around" within the squad.
"I have completed all the talking in recent days that I required," said Stokes.
However, following the opener scored a knock of 85 on the penultimate day in the third Test, he commented: "I missed those remarks."
"I didn't see and wasn't really looking out for it. Our approach is to take everything that is said in the media with a pinch of salt," he added.
Raw Conversations and Steady Philosophy
The captain made the "fragile individuals" observation after his side were beaten in the second Test to fall 2-0 down.
The team subsequently went on a break to Noosa between the second and the upcoming matches.
Prior to the Adelaide contest, Stokes said his players had held "honest" talks and he had urged them to "display some fight" in their battle to stay in contention in the series.
Nevertheless, the Kent batsman asserted the guidance from the captain and head coach McCullum had stayed consistent with their prior three years in charge.
"The atmosphere has been extremely upbeat, the same as always," noted the opener. "It's just trying to be optimistic, play our way, with great liberty. We believed we were capable of an extraordinary feat entering this game."
The Hosts Close of Historic Ashes Triumph
The opener's wicket late on Saturday was part of a crucial triple-strike by Australian off-spinner Lyon.
Lyon's three wickets in a short spell – including the wickets of Harry Brook and Ben Stokes – meant the chasing side six down for 207 chasing a daunting total of 435.
This means, Australia need just four more wickets on Sunday's last day to move to an insurmountable 3-0 lead with three Tests.
A loss will extend the English team's drought in this country to 18 consecutive matches and ensure a fourth straight away Ashes defeat.
This series is set to be decided in just eleven days of play – with England fell the initial matches in rapid time each.
The last time 1921, when the Australians completed victory in England in eight days, has the destination of the Ashes urn been decided so quickly. The hosts have also won in eleven days on two other instances in the 21st century.
"It's disappointing," admitted the batsman. "Our goal was to win the Ashes and now we are facing elimination at this point."
"There will still be significant pride at stake and we will definitely view it with that mindset," he continued.
"It's been difficult. Australia is a formidable side. It was inevitably hard touring here against them. They entered as the favourites coming in to it have demonstrated their quality."
Pope's Position In Question
While Crawley's performance in Adelaide likely secures doubts about his short-term place in the side, Ollie Pope looks under threat for his position in the Melbourne Test starting December 26th.
The Surrey batsman was out for 17 in the team's second knock on Saturday, adding to his poor record versus Australia.
Across 16 Ashes innings, the Surrey man has never made a fifty and boasts an average of just 17.62.
Only one other England player in over a century – Dennis Amiss – has featured an equal number of innings in the top six in the Ashes and recorded a lower average.
But, the opener insisted any suggestion Pope is being scrutinised originates with "the media" – referring to the press – "and not within the team."
"We all know how good of a player he is," added he. "He has had a productive 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 finished.
