"His response summed up what Bangers, the person, is all about," Klinger wrote in an article for Players Voice.
"He thanked me, then turned the discussion to my family. He said my wife, Cindy, is going through something of far greater significance than what he was experiencing in South Africa. That, he added, was true perspective.
"Cindy was diagnosed with breast cancer a few months ago.
"Personally, I think that's a pretty remarkable way for a 25-year-old bloke to respond in the middle of the biggest crisis of his life, one that was being documented all over the world."
Cricket has had years to get to know Smith and Warner, who have been banned for 12 months and stripped of the captaincy and vice-captaincy, but a lot less time to understand Bancroft.
The opener made his test debut in last summer's Ashes and is still new to the international scene. Klinger revealed in his early days playing first class cricket Bancroft was so intense and highly strung senior players like Marcus North and Adam Voges had to work hard "to relax him and help him find perspective on and off the field".
One of the biggest takeaways from Bancroft's press conference last Thursday after touching down in Perth was how filthy he was for giving up his spot in the Test team after working hard to earn it in the first place.
"The thing that breaks my heart the most is I've just given up my spot in the team to somebody else for free," Bancroft said.
"People know I've worked so hard to get to this point in my career, and to know I've just given somebody else an opportunity for free is devastating for me."
Klinger said Bancroft "is the hardest trainer I have encountered anywhere in the world in my 19 years of professional cricket" and takes feedback on board better than most young players. It's those traits that make Klinger confident we'll see Bancroft back in the national fold one day.
"I reckon Cam has got what it takes. This won't be the last we'll see of him in the baggy green. He'll make the country proud again," Klinger wrote.
Bancroft, Smith and Warner may still appeal their punishments handed down by Cricket Australia, with that decision to be known by April 11.
Hearings over the level-three charges and/or sanctions issued to the trio are expected to take place — if needed — on Wednesday week.
There remains a possibility they will take their medicine and CA will put a full stop to the ball tampering saga that has already cost the governing body millions in sponsorship and affected TV rights negotiations. However, that possibility seem to be fading fast.
Warner is understood to be particularly keen to put his case to an independent code-of-conduct commissioner.
Smith and Bancroft have also sought legal advice and are believed to strongly considering challenging their bans. CA's code of conduct dictates players can accept sanctions at any point "prior to the commencement of the hearing at the time/place specified in the notice of charge", which is understood to be April 11.
