NSW back-rower Ryan Hoffman has revealed he was once approached to play for Queensland but did not feel comfortable about pulling on the Maroons jersey worn by his father, Jay.

With the ARL Commission having introduced a father-son rule for Origin, Wendell Sailor's son Tristan and Adrian Lam's son Lachlan are expected to play for Queensland in coming years despite having grown up in NSW.

However, Hoffman said he could never play against the Blues, and told how he had rejected an approach from Maroons officials, who insisted he was eligible after representing Queensland under-19s while playing for Melbourne Storm's feeder team, Brisbane Norths.

"I said no because I had never lived in Queensland so it wouldn't have been right," Hoffman said on the eve of his 11th Origin appearance for NSW at Suncorp Stadium on Wednesday night.

"To me, that is not what State of Origin is about. Queensland is not where I am from and it is not where I played my junior league.

"I went to school with Beau Scott, I played a lot of junior footy with Greg Bird and I played in Wests Tigers junior development teams with Robbie Farah, so I grew up with quite a lot of these guys in the NSW team and it would have been weird to play against them."

Asked how his father felt about him playing for NSW after he had packed down at hooker for the Maroons three times in 1979 and 1980, Hoffman said: "When I play for the Blues, dad is a Blues man through and through, but when I am not, he is a Queensland man."

Hoffman did his father proud in Origin II by winning the NSW players' player award in their historic 6-4 win, which secured the Blues' first series victory since 2005.

Even Storm teammates Cameron Smith and Billy Slater were pleased for him.

"Immediately after the game, they were the first to come and congratulate me," Hoffman said. "We have achieved so much together over 13 years and they know how much Origin means to me, they know how hard I have worked and how disappointed I have been in previous years. Three times a year for 80 minutes, they are just blokes in a Queensland jumper, but as soon as that siren goes we are the best of friends. That is what Origin was built on. It is still Queensland versus NSW, and you want to win that game, but afterwards you are mates."

After making his Origin debut in 2007, Hoffman has played through most of the Maroons' eight-year domination of the series. "I could almost feel the weight lift off my shoulders and I am sure a lot of the boys were the same," he said. "Eight years is a long time and we had been so close so many times. A lot of times in the third game, we have been knocked off and it has come down to one pass, one dropped ball or one missed tackle.

"I think that, as the night wore on, we started to realise the enormity of what we had achieved because this Queensland side we have beaten are one of the greatest sides of all time, they really are."

However, he was confident NSW could still have won the series at Suncorp Stadium if the match was a decider.

"We achieved something in that first game, it was the first time since 2005 that NSW had won a live game in Brisbane and I think that gave us all the confidence in the world that we can beat Queensland in Queensland when the series is on the line."
