New Fremantle coach Justin Longmuir wants his side to defend smarter in 2020.

Speaking on SEN’s Dwayne’s World, the former Collingwood defensive coach said he feels the team needs to reduce the amount of turnovers they commit coming out of defence.

“I think we need to really educate our players on identifying which turnovers are the right ones to attack off of and which ones you need to take your medicine and go a little bit more slow and a little bit more systematic,” Longmuir said.

“We want to be a little safer coming out of our back half. I think you see Geelong and Richmond and those teams don’t cough up turnovers in their back half which makes it really hard to score against them.

“If our defence is aggressive and we are able to force turnovers in the front half, that should give us good looks in offence.

“First and foremost we want to make sure that we are defending really strongly and forcing teams into turnover and that’ll give us good opportunity to attack off those turnovers.”

The Dockers’ first game in the post Ross Lyon era will be against Carlton in week two of the Marsh Community series.
