'Their problem': Broncos' star recruit unfazed by slump

Haas and fellow Bronco Kotoni Staggs broke Blues camp on Thursday to watch the reigning premiers face South Sydney at Accor Stadium, where the clubs celebrated the career of their shared former player Jai Arrow.

On a night of emotion and commemoration, the Broncos suffered a 48-6 defeat, the worst of Michael Maguire's coaching tenure, and slumped to a six-game losing streak.

With a 5-9 record, the Broncos are at risk of becoming the first team since Wests Tigers in 2006 to miss finals the year after winning the premiership.

But alarm bells are not ringing for Barnett, who will partner Haas in the front row when the Blues fight to seal a series victory in Origin II on Wednesday.

"This year, for the Broncos, is their problem," Barnett said.

"I'm going there next year, so I'm fully focused on my job here and then my job at the Warriors. I don't have any more attention to them at the moment, just because I'm going there next year."

Barnett pointed out the Broncos of 2027 were a far different proposition, given the imminent departures of Haas and Adam Reynolds, and his and Jonah Pezet's arrivals.

"If you look at their team next year, you look at their team this year and you look at our Warriors team this year, they're going to be completely different teams next year," he said.

"I'll worry about that once I finish the job at the Warriors."

Barnett made the first error that set the tone for a clumsy first half for the Blues in game one, and was one of a handful of defenders who failed to clean up a kick ahead of Queensland's third try.

But he insisted it was a "simple fix" to avoid another slow start at the MCG.

"If we fix up the errors, we have more ball where we can put more fatigue in them and we tackle better as individuals, that'll help our start," Barnett said.

"We missed the mark there, but it's a simple fix if everyone gets on board and buys in, which we've been training and actioning."
