As one of modern-day rugby league's finest, Cooper Cronk doesn't think he could do what Lagi Setu has done for Melbourne this year.
Setu has returned from to the game's elite level after two years away while undertaking a Mormon mission.
The 24-year-old has lost around 15kg, regained his touch, and cemented a regular spot to help the Storm to an unbeaten start to the NRL season.
"You have to admire a guy who walked away from the game to follow a belief of his," Melbourne halfback Cronk said.
"To be able to come back and be able to play that brand of football, it's pretty inspiring actually.
"I don't think I could go away for two years and come back and perform the way he's doing."
Neither did Setu just a couple of months ago.
He hadn't touched a rugby league ball for 18 months - his only regular exercise walking or bike-riding the streets of England's West Midlands spreading the Mormon message.
So as he pushed an out-of-shape body through brutal pre-season training, the ex-Brisbane Bronco questioned whether his rugby league comeback was misguided.
"I was fighting demons out there. I was thinking `was it a wrong move coming back?'," Setu said.
"Sometimes you've just got to hang on.
"There were people on my mission who just wanted to give up, who'd lost hope.
"But as you try and encourage them, like the coaches here do for me, the people on the mission, they change.
"I see myself doing the same thing as well."
Setu has certainly won his teammates over - his try against the Bulldogs last week sparking big celebrations.
Now the likeable Setu faces his most difficult challenge yet on Good Friday - coming up against the Broncos, the team he quit to follow his religious calling.
Whatever his season brings, Setu has exceeded his personal expectations.
A return to Suncorp Stadium with the Storm suggests he has come a long way from when coach Craig Bellamy laid on eyes on him for the first time.
"I was 117kg at the time I met Craig in England ... it was funny, he saw me and I was assuming he just thought `what have I signed here?'
"For the first two weeks in pre-season I was running down the sideline trying to avoid the contact - I looked like I was doing beep tests.
"But anything is possible if you put your mind to it - anything in life."
