Stuart Reardon came into the Tri-Nations tournament needing to prove his class as an international winger.
Reardon's displays have been a revelation for Great Britain
And he has done just that.
While not a total novice to the position, the vast majority of Reardon's top-level experience has come at full-back.
But three tries and four virtually error-free performances later, the 23-year-old has made the number five jersey his own.
His form has been so good that he goes into Saturday's final as one of Britain's potential match-winners.
Reardon has alternated between full-back and wing with Bradford this season.
But an absence of world-class specialists convinced Lions coach Brian Noble to throw him in at the deep end, handing him his debut against Australia.
Probing for a weakness, Australia's kickers subjected Reardon to an aerial bombardment.
But he came up with emphatic answers to every question the Kangaroos' kicking game asked of him.
That unflappable display set the tone for his whole tournament.
Far from being a weakness, Reardon has proved himself a finisher of the highest order with crucial tries against both New Zealand and Australia.
But his performances have come as no surprise to Robbie Paul, his club captain at Bradford.
"I think he'd have been quite uncomfortable coming into the tournament as a winger," said Paul, who faced Reardon in the Tri-Nations while playing for New Zealand.
"At this level, it's very hard to adjust. Everybody on the pitch is a quality player and virtually everybody is in their regular position.
"The other teams are no fools - if they think there's a weakness then they'll do all they can to exploit it.
"But anyone who thought Stuart might be a weakness has been sorely disappointed."
Paul said Reardon's attitude had always impressed him, ever since the youngster arrived at Odsal from amateur club West Bowling ARLFC in 2000.
"He understands that playing rugby league is his bread-and-butter and that everything else must come second," said Paul.
Reardon has coped with the physical aspects of international rugby
"I know he's made great sacrifices on a personal level to become the player he is.
"If I was a coach, I'd love him in my squad. It's not often you find a player as talented as him with such a strong work ethic."
After a solid grounding at Bradford's academy, Reardon swiftly went through the gears as a professional.
After loan spells at Featherstone and Salford, he popped up to win the prestigious Harry Sunderland Trophy with a brilliant performance in the 2003 Grand Final.
Reardon has not had long to wait to make an impact at international level either.
He made his England A debut before making his Bradford debut and was nominated for the international newcomer of the year award after just four Lions caps.
And if Reardon can continue his rich vein of form in Saturday's final, Great Britain could finally end their wait for a major trophy.
