NSW Blues' Jack Wighton learns how tough it is to win State of Origin in Queensland the hard way

Which is why the NSW Blues centre knows better than most how tough State of Origin is at Lang Park.

He remembers last year. When he threw the intercept for his Queensland counterpart Dane Gagai to race almost the length of the field to spark a Maroons win.

But the Canberra Raiders five-eighth also has that great gift of leaving mistakes in the past and working to ensure they don't happen again.

As he showed in the Blues' emphatic 34-10 victory in game two at Sydney Olympic Stadium on Wednesday.

After a tough Origin I, where he missed a tackle on Gagai to allow the Maroons centre to score, Wighton responded to get the better of the South Sydney back to cross straight after half-time to effectively seal the win for the Blues.

But he knows how tough Origin in Queensland can be after he came off the bench in the series opener there last year.

The 2020 Blues are looking to create their own piece of history and join the 1994 and 2005 teams by winning the decider on enemy territory.

If they pull it off, it will also be the first time Blues coach Brad Fittler has won at Lang Park since taking the NSW reins.

Wighton said they only had themselves to blame after losing Origin I in Adelaide last week, when the Maroons upset them 18-14 to set up a grandstand finish in their home town - where they've only lost two of the 11 deciders played there.

"Yeah I threw the intercept. I've played there, I've been there," Wighton said when asked about playing Origin in Brisbane.

"I make it hard for myself. I do things the hard way. It's going to be very tough. They're a great side in Queensland and we'll just see how it plays out.

"They're going to grow another leg up at Suncorp as they always do.

"We've set a very, very hard task for us losing that first one. But that's football and we've just got to do our best."

Wighton revealed the faith Fittler showed in him was a key reason for him turning his form around from game one.

Fittler stuck with his centre pairing of Wighton and Clint Gutherson after both struggled in opening loss.

Wighton responded, not only scoring his try - where he was too powerful for two Queenslanders - but also making four tackle busts as well.

Now he'll look to repeat that effort when they travel to Brisbane on Wednesday.

"You make a mistake on the big stage like that, but then when your coach gives you confidence and puts you straight back in the team that means more than anything," Wighton said.

"That's where I got my confidence. Tackling has always been one of my big things.

"A little bit of fine tuning and go again the next game, that's what I try and do."

Wighton felt he was one of a few Blues players who "knew they had more" to give to the cause.

And that played a big role in the vast improvement in NSW from the first to the second games.

They went from a team that struggled with the ball in hand to one that was almost unstoppable at times.

Although as Fittler said after the game, a lot of things went right for the home side.

They took full advantage of the absence of Maroons five-eighth Cameron Munster, who was forced off after slamming his head into the ground and didn't return because he failed the concussion protocols.

Wighton revealed the mindset that's enabled him to go from someone who let mistakes get to him to one who can put them behind him.

"Obviously it was better than last week. Last week was a difficult day in the office, but that's football sometimes," he said.

"Sometimes you mess up and it just happened to be on the biggest stage.

"You take that in your stride and you've just got to learn from it and go again don't you.

"I love making it hard for myself you know. It's definitely something, they're big things, but even them games aren't that big if you keep sticking at it.

"You just stick at it and hang tight. That's the game we play. I'm going to have them mistakes it just depends when."
