Broncos Jamayne Isaako.

Broncos captain Darius Boyd says he is prepared to stay at left centre after his positional switch worked a treat in the 50-18 win over the Penrith Panthers.

Brisbane coach Wayne Bennett moved winger Jamayne Isaako to fullback and Boyd to left centre after being concerned about several defensive lapses in the previous week’s 26-6 loss to the Warriors.

The Panthers had no joy on Boyd’s side of the field with his communication vital to keeping the left-edge defence rock solid.

Boyd, who has played in the custodian’s role for most of his career, said "the team is first" and he would be prepared to stay there and let Isaako play in his preferred fullback position if that is what the coach wanted.

"I played a lot of centre in my junior career especially and have little bits of NRL experience there too," Boyd said.

"I am pretty experienced and I know what I bring. I wanted to come in with a defensive mindset and really talk next to Milly [Anthony Milford], Alex Glenn and Corey Oates in particular and I was happy with how it went.

"Jamayne is the future of the club. He does all the extras that you'd want of a young guy and you couldn't fault him tonight." 

The win capped off a remarkable turnaround for Brisbane after the Warriors game last Sunday but Bennett was not getting carried away with the in-form Cronulla Sharks on their way to Brisbane next Thursday night.

"We can't afford to get around and tell ourselves we are sensational," Bennett said.

"We've won nine out of 12 games but we just need to nail games we should be nailing. Hopefully in a month's time we can be more consistent than we have been, particularly last week which was pretty disappointing."

The influence of powerhouse forward Tevita Pangai jnr on the Broncos performance cannot be underestimated with the Tongan international's two try display in a 31-minute cameo in the first half giving the side momentum and confidence.

Bennett said he was rested in the second half because the  hamstring injury that kept him out of the Warriors clash had tightened up.

"He'll be right. Thirty minutes of Tevita is better than no minutes of Tevita," Bennett said.

Boyd said Pangai's second try, where he wrestled with five Panthers defenders and got the better of them to score, was a huge lift to the side.

"Only certain players can do those type of things and Tevita is one of them. Just having him on the field, I know the boys get confidence out of it and he brings a lot of energy to the group," Boyd said.
