Brisbane's newest recruit Korbin Sims believes teammate Josh McGuire will be the Broncos' No.13 come Round 1, with the 25-year-old hoping to take McGuire's position in the front row if it becomes vacant.

McGuire would be following in former captain Corey Parker's footsteps if he made the positional change, with Parker often playing in the front row before his permanent move to lock in 2009.

Parker's retirement last year has given coach Wayne Bennett a major decision to make as the 2017 NRL season fast approaches.

Up and coming big men Jai Arrow and Tevita Pangai Jnr have staked their claim for the No. 13 jersey, but it now appears a positional switch for McGuire will be the most likely scenario.

This would be the best situation for Sims, who despite having history in the second row, was signed with Brisbane to add depth to their front row stocks.

"Front row is my position and I want to play there for the Broncos this year," Sims said.

"I don't mind a bit of lock, but I think Josh McGuire will start there for us this year.

"I played second row in our trial win against the Sharks, which I don't mind because I can get the job done there.

"In saying that, I feel like I have a lot to learn about that position if I am going to be good enough to play there in first grade."

Sims's arrival at Red Hill has not only added depth to the Broncos' forward pack, but also the aggression.

The former Newcastle Knight was a standout in Brisbane's 30-12 trial victory over the Cronulla-Sutherland Sharks on Saturday night, making a number of bone-rattling hits that brought the huge Redcliffe crowd to their feet.

This side of Sims's game is something the Fijian international prides himself on, with his huge hitting a big reason as to why he was targeted by the Broncos.

Hopeful of a Queensland Maroons call-up in 2017, Sims said he is looking forward to becoming Brisbane's new enforcer.

"It's always exciting when a big hit comes off," he said.

"I want to bring aggression to this side and I think that's one of the reasons I was brought to this club.

"A bit of aggression never hurt anyone and I think if you can control it then you can use it to your advantage."
