Darcy has been one of the competition’s best big men over the past two years,but the arrival of Jackson has raised questions about who will assume the lead ruck role.
Fremantle are still formulating a plan about how Jackson and Darcy will split their time between the ruck and forward line,and the pair have been enjoying the training battles against each other.
“It’s good fun. Lukey’s a character. He’s an extremely good athlete. He pushes me in training,” Darcy said.
“He’s a really good runner. He covers the ground extremely well. If I’m ball watching a little bit,he’s spreading out wide. It’s really helping me a lot.
“He’s pushed me every day.”
Darcy said it would take time for him and Jackson to build their on-field chemistry.
