Ben Hunt says he can’t overplay his hand as the Broncos must quell the red-hot Rabbitohs on Thursday night.

Brisbane playmaker Ben Hunt believes Ben Barba’s switch to the halves has made his job easier, not tougher, and turned the Broncos into a more dangerous NRL outfit.

Hunt has starred in his first full season at halfback but his form suffered a worrying dip in losses to Melbourne and Manly after Barba was moved to five-eighth.

There was speculation the club’s decision to dump mentor Anthony Griffin had rattled the 24-year-old while it also seemed the No.7 was struggling to strike the right combination with Barba.

But Hunt said his troubles all boiled down to himself overplaying his hand.

“I just think those two games I was just looking for too much,” he told AAP. “I was going out there and trying to find plays that just weren’t on instead of playing a simple game and playing what was in front of me.

“It wasn’t the coach’s decision, it was just the way I played.”

Hunt was back to his best in Brisbane’s 41-10 thumping of Canterbury on Friday night – their biggest win of the year.

He scored two tries and was creative on the right side while Barba, growing in confidence after swapping with Josh Hoffman, also shone in sharing playmaking responsibilities on the left.

“I think it’s going really good,” he said. “Barbs has been one of our better players the last couple weeks and he’s really taken that position on and it really helps me.

“When he’s firing it takes a bit of pressure off my side and if people are doubling up on him then it gives me an opportunity to have a go.”

Hunt, leading the Dally M medal count before it went to a secret count, believes the Broncos must lift again to upset a bruising South Sydney on Thursday night.

The Rabbitohs are firing after outmuscling pasesetters Manly 23-4 to be back in the hunt for the minor premiership.

It looms as a season-defining clash for Brisbane who remain 10th.

“It’s going to be a massive game for us and one that we have to win,” Hunt said.

“They really came out and dominated Manly and that’s a credit to them and how well they’re going. We have to be as good, if not better, than what we were.

“They’re going to come out and try and dominate us.

“They can hurt you wherever they want with a couple of good young halves and Greg Inglis out the back and look at the size of their forward pack. They have size everywhere.”
