So single-minded a Test cricketer was Justin Langer that team-mates have often spoken of the almost monastic fanaticism with which he pursued team and individual success for Australia. So it was telling that he spoke with enormous admiration for the cricketer David Warner has become, epitomised by his busy intensity in Australia's victory in their tri-series opener against West Indies.
The past week in New York and Guyana has been the first time Langer was able to get a look at Warner up close since he resigned as Australia's assistant coach to take up the head coach role with Western Australia in November 2012. At that point, Warner's performances were strong enough, but he was on a spiral of bad behaviour that led to his suspension from part of the 2013 Ashes tour for throwing a punch at Joe Root in a Birmingham nightclub.
Three years on, Langer speaks of Warner in the same way as he does about former team-mates and close friends Ricky Ponting and Matthew Hayden - an unlikely scenario in the past, and a measure of how far the teetotal and focused Warner has come. This applied not only to the national team, but also to his work for Sunrisers Hyderabad in the IPL, where Warner played a large part in securing the trophy for his side.
"I just admire David Warner so much, it's not just his performances on the field but his actions off the field," Langer said ahead of Australia's second match against South Africa on Tuesday. "He'd probably be the first to admit that a few years ago he was pretty hard to manage; he liked to do things his way. But really he looks super-focused at the moment. He's super-fit, you see his running between the wickets, he's an elite athlete now and that takes great discipline.
"He's been rewarded for that, he's been rewarded for his discipline and he should be really proud of the fact he has become a great role model for our young Australian cricketers and cricketers around the world. He's become so fit and disciplined in what he's doing and he's so consistent, that's what great players do. I really respect David Warner's career, but I really respect his last year or so, because you can really tell, like a lot of great players do, there's a trigger moment where he really switched on and he's now cashing in on that."
Expanding on this theme, Langer said he was delighted by the Australian players' willingness to adapt to foreign conditions without so much as a warm-up match, a mindset vital for bigger battles ahead, notably next year's Champions Trophy in England.
"What I feel is it's a fantastic team of young men," Langer said. "There's no trouble-makers. They're all really good blokes. They all work hard, they're all hungry. We had two things [to focus on before the match against the West Indies]; the first was to adapt and the second was to look after each other. We all get on well, we've got good camaraderie and they're really good people.
"I was nervous, particularly about some of those big fast bowlers coming back. They're all fit and they've got some bowling under their belts, but not match practice. I always get nervous when we don't have match practice. Having said that, I thought one of our main themes was being able to adapt. We've got a different coaching staff, we're in a different country, we're playing on different wickets. Our main theme was adapting to the conditions and we did that very well.
"Looking after each other is a lot easier - I always maintain - when you have that good camaraderie in the group. It's like the glue that keeps things together when you're under pressure. I like coming into a team that gets on well and everyone's good mates."
Langer, never one to take the game or success for granted, was aware South Africa could well be in a fighting mood following their opening defeat to West Indies. Warner's professionalism and the team's good spirit should only help Australia's cause as they seek to notch up another win.
