Makasini and Taupau-Moors fit the height, size, fitness and speed description, Ethan Roberts fits the description and as you say the Taotua brothers and Lachlan Broederlow also fit the description.
The Taotua brothers and Broederlow are frustrating as they always show glimpses of using their size and athleticism to their advantage, but seem to fade in and out of games and fade in and out of using their aggression to advantage.
Big year for all 3 of them as they are good enough to push for NRL in the 2nd half of the 2026 season, but if they don’t put in 💯 they will be out the back door.
