Payne Haas is a physical specimen to be reckoned with but the Broncos prop credits his father Gregor for his remarkable resilience and instilling in him the "mental edge" over opponents with extra training sessions on his days off.
The 19-year-old was on song against the Warriors in the 18-all extra time draw at Suncorp Stadium where he scored a barnstorming try, ran for 201 metres and made 41 tackles.
Haas was the most dominant forward on the field in the early exchanges and it was his last-ditch tackle on Chanel Harris-Tavita when the Warriors utility was certain to score that showcased his huge engine and desire.
Haas, who stands at 194cm and weighs 119kg, told NRL.com last year how his father had taken him for gruelling sessions as a youth on a kilometre-long "hill of pain" near their Gold Coast property where he learned the value of extra effort, endurance and mental strength.
It is an ethic that Haas said was still as relevant today as it was back then.
"I credit my dad for my engine because he still trains me hard. I live at home now and on my rest days I train with him," Haas told NRL.com.
"We do what I call 'sweat-ups' and I do some gym work and boxing with dad. He gets me through the pads. He taught us all how to box.
"A sweat-up is just getting the sweat up with your training. I have spoken to a few people about the benefits of training on your day off because it is a good mental edge to have on your opponents on the weekend.
"Dad wants the best for me and is still my coach on the side when I am not at the Broncs."
Haas is not the only Bronco who does extras on his days off. Jamayne Isaako practices his goal kicking on rest days at Brisbane HQ while rookie winger Herbie Farnworth also trains with his uncle Brian Foley to sharpen his footwork and speed, which comes as no surprise to Haas.
"Herbie is another hard working kid with a good ethic and that is going to show in the years ahead. I still think he is killing it at the moment," Haas said.
Haas was modest about his 87th-minute tackle on Harris-Tavita and said it was the kind of effort that everyone who wears a Broncos jersey needed to have. The Broncos can improve on their attack but the grit they displayed against the Warriors without the football is what impressed Haas the most.
"For me it is about doing my job for the team and having real pride in wearing the Broncos jersey," Haas said.
"I think our performance showed that even though we are a young team we can still fight it out. Only time will tell how we good we are going to be.
"There are plenty of lessons to come out of that draw. We had a good 15 minutes to start, but we had trained all week on their fifth and last plays because they are the first in the comp at scoring on the fifth. We didn't shut them down with that and it put us behind."
It is no surprise that Haas admires forwards who have big engines and are workaholics. It is why he is tipping 21-year-old Patrick Carrigan to build on what was one of his best games yet in a Broncos jersey.
Carrigan made a career-high 130 running metres and 31 tackles in his 37 minutes against the Warriors in the best game of his 10 Telstra Premiership appearances to date.
"Patrick was a massive for us and what you saw is only a glimpse of how good he is going to be," Haas said.
"Once you get to watch him fully you will understand why I consider him one of the best that I have ever played with.
"I am really excited for him and really proud of him and you are going to see him become a real force because he does all the gritty things and all the little efforts. When someone is there to get whacked he is going to whack them. He has got one of the best engines at the club so I can't wait to see him fulfil his potential."
Haas said the Broncos needed to back up their performance against the Bulldogs on Thursday night at Suncorp Stadium where he is salivating over taking on Maroons prop Dylan Napa and company.
"They have got a big pack and big Naps. I can't wait," Haas said.
