Walyalup (Fremantle) forward Josh Treacy is adamant the Dockers are a more dangerous team when they play two ruckmen and three tall forwards despite their loss to Collingwood on Thursday night.

The Dockers’ coaches are analysing their options for Saturday’s clash against Greater Western Sydney after they dominated the clearances and inside-50s against Collingwood but took just six marks inside 50 and lost by 14 points.

Experts have called on coach Justin Longmuir to change his commitment to playing Luke Jackson and Sean Darcy in the same team after the Dockers lost both games since they were both available.

Treacy is confident Darcy will recover from a jarred knee to take on the Giants and said playing inside 50 was significantly easier when the Dockers selected two ruckmen and three tall forwards.

“I think it’s very beneficial because it allows us to stay taller in our forward line which is what we want and personally what I like when we’re a bit taller in the forward line,” Treacy explained.

“I think it’s a really good dynamic for us. It’s two guns of our teams that we really like to have in there and I certainly love having them in there.

“I think three talls has worked great for us ever since I’ve been here. It generally challenges a lot of backlines and it works in our advantage. I didn’t see it as a disadvantage on the weekend.”

Treacy, Pat Voss, Oscar McDonald and Josh Draper have all been asked to play as the back up ruckman this season when only one of Jackson and Darcy has been available.

Treacy said the forward line didn’t feel as strong as soon as one of the other big men moved into the centre square.

“It certainly makes it a bit more challenging for us talls who are down there,” he said.

“Especially sometimes it might only be one tall and that’s a really big ask. So I certainly prefer to play two genuine rucks and have three tall forwards as well.”

The Dockers spent Monday conducting primary school visits but will have their main training session of the week on Tuesday before flying to Sydney on Thursday.

Treacy said the players were keen to build on their efforts around the ground against Collingwood and fix the areas which left them struggling to score.

“Obviously we were disappointed with the loss but we were quite happy with the step forward from the week before and there was a lot to take out of it,” he said.

“Clearly we wanted to walk away with the four points but we walked away with a brand of footy that we were happy to play and know it is going to stand up more often than not.”

Fremantle will be known as Walyalup for Sir Doug Nicholls Round.
