Fremantle are set to select "the best player" available at next week's National Draft when they're on the clock at Pick 30.

The Dockers have seen their draft hand shift, having moved on their opening selection of Pick 13 to Melbourne in a move that saw the Cockburn club attain Luke Jackson.

That trade has left them with a hand consisting of Picks 30, 43, 44, 65, 70 and 77, meaning they currently won't feature on the opening night of the draft in what will showcase just the first round of selections.

They'll enter midway through the second round at Pick 30, before holding two successive third rounds picks and a trio of later selections.

Their first pick will be the focal point for the Dockers and head of player personnel David Walls, who revealed to SEN WA that Fremantle will look toward the best prospect still on offer at Pick 30.

The Dockers will also look to add to their spine, wether that be attaining a ruckman, key defender, or both.

"Pick 30 will be the best player and then after that we'll try and address the needs," Walls said.

"We need a developing ruck and a key defender will be nice as well. We had great years from Brennan Cox, Alex Pearce last year, who got through injury free, and we look forward to seeing Joel Hamling this year, but we need a younger defender we can try and develop."

The ruck void has been opened after the departures of Rory Lobb and Lloyd Meek, who were traded to the Western Bulldogs and Hawthorn respectively.

The aforementioned Jackson will be able to take some of the workload from first-string tall Sean Darcy, however depth options are still required.

The Dockers also lost swingman Griffin Logue to North Melbourne, seeing their tall defensive options also take a hit.

"The backline held up really well last year, and there are other options like Luke Ryan who was All Australian as a full back," Walls added.

"Ethan Hughes can play taller, Heath Chapman is 193cm, but Joel is critical to play on those 205cm key forwards that we see these days."

The National Draft will commence next Monday, November 28, and run across two night, while the Rookie Draft will take place on the Wednesday.
