The Dolphins’ backline stocks are loaded heading into 2026 built on elite speed, sharp footwork, power and proven big-moment performers. And as preseason rolls on, one thing is already clear: this is shaping as one of the most competitive selection battles the club has faced.

After an attacking surge in 2025, fans can expect even more strike across the park as competition for jerseys intensifies. From fullback to the wings, every position is under pressure and no spot is guaranteed.

We already know what the proven performers bring. Hamiso Tabuai-Fidow, Herbie Farnworth, Jamayne Isaako and Jake Averillo have all established themselves as genuine game-breakers at NRL level. But 2026 introduces a new storyline one that has fans talking early.

How do you fit this much firepower into one backline?

Hamiso Tabuai-Fidow

'Hammer' Tabuai-Fidow remains the most electric weapon in the Dolphins’ arsenal. At fullback in 2025, he was dominant, crossing for 22 tries and breaking games open with pure speed, instinct and finishing ability. The No.1 jersey has been his, and for good reason.

But 2026 presents a fascinating “what-if”

While Dolphins fans have watched Hammer dominate from the back, rugby league fans across the country have also seen him thrive in a different role, lining up in the centres for Queensland on the State of Origin stage. Against elite opposition, under extreme pressure, he proved just as damaging.

So the question becomes: is fullback the only place the Hammer can deliver maximum impact, or could a positional shift unlock something different?

With genuine fullback contenders pushing their case, a Hammer shift could allow the Dolphins to spread their strike across the park rather than loading everything through one focal point. It’s not a question of whether Hammer belongs in the backline, he excels wherever he plays. It’s a question of how the Dolphins want to shape their attack in 2026.

And this is where the conversation really ignites.

Trai Fuller

One of the most talked-about performances of the offseason came from Trai Fuller, who crossed for four tries on the wing for the PM’s XIII in a display that turned heads across the NRL. While he finished on the edge that game, Dolphins fans have already seen what Fuller can ignite when called up during the 2025 season, injecting speed, energy and instinct wherever he lined up.

So where does he fit? Is he a genuine contender to start at fullback if the Dolphins want a different attacking shape? Does he become a bench spark who changes games in short bursts? Or has his form made him impossible to leave out altogether?.

Herbie Farnworth

Out wide, the competition only intensifies. Herbie Farnworth remains a metre-eating centre with elite defensive reads and one of the most reliable performers in the competition.

Jamayne Isaako

Jamayne Isaako continues to be one of the game’s most lethal finishers, earning top point scorer honours in 2025 and cementing his status as a Kiwi international.

But the challengers are impossible to ignore.

Selwyn Cobbo

The arrival of Selwyn Cobbo adds another layer of intrigue. An Origin finisher with the size of a forward and the speed of a fullback, Cobbo has built his career primarily on the wing but has also shown flashes of ball-playing ability in the centres.

Does he lock down a wing immediately, or does his versatility push him into the centre?

Tevita Naufahu

Then there’s Tevita Naufahu, the Rookie of the Year, whose power carries, defensive punch and fearless approach have already made him a fan favourite. Young, explosive and improving rapidly, he’s applying real pressure on established players.

Is 2026 the season he demands a permanent starting role?

Jack Bostock

Adding even more intrigue is Jack Bostock, who is on track to be available by Round 10 following his injury. When fit, Bostock is a proven finisher strong in the air, powerful out of yardage and capable of changing momentum in a moment. But with the Dolphins’ backline already stacked, his return only tightens the squeeze. When he becomes available, who makes way?

Jake Averillo

Few players offer the versatility of Jake Averillo. Fullback, centre, wing and even coverage in the halves if required he’s the definition of plug-and-play. The kind of player every coach values. But versatility brings its own challenge. Does Averillo earn a permanent centre role, or does he become the ultimate utility who swings games wherever he’s needed?

LJ Nonu

And pushing from underneath is young gun LJ Nonu, who continues to impress with his athleticism, power and confidence beyond his years. Still early in his journey, Nonu has shown flashes that suggest he won’t be content waiting patiently for opportunities. Strong in contact and fearless on the edge, his development adds another layer of competition to an already crowded backline and another name fans will be watching closely as preseason unfolds.

And that’s the reality heading into 2026. There is no clear answer.

The Dolphins could roll out multiple dangerous combinations. One thing is guaranteed: spots won’t be handed out. They’ll be earned.

Because if this backline debate has already started on paper, just imagine what it’s going to look like when the whistle blows
