The Dockers have emerged as the most surprising premiership contender of 2022, with Justin Longmuir now getting the best of out of his balance of emerging stars and seasoned heads.

But while Fremantle continue to rise up the ranks after years of rebuilding, some pieces of the purple puzzle are yet to click, with their final solution perhaps relying on players currently plying their trade at rival clubs.

With the Dockers already in the middle of trade and free agency reports and rumours this year, they loom as a major player in the upcoming off-season for both gains and losses.

Looking at the former, we cast our eye over five players Fremantle could consider targeting in 2022.

TRADE TARGETS: ADELAIDE, BRISBANE, CARLTON, COLLINGWOOD, ESSENDON

2. Luke Jackson

Perhaps an obvious option for the Dockers given their already reported interest in the premiership Demon, Luke Jackson would be a perfect fit for Fremantle.

His ability to play as a target inside forward 50, aid the ruck workload and move around the ground would partner well with first-string tall Sean Darcy, who may be without a right-hand man should Rory Lobb return to the east coast.

With Jackson out of contract and yet to make his future known, a request to move back to his home state continues to become more likely the longer Demons fans are left to wait.

Melbourne will rightfully demand a war chest of assets to hand Jackson to the Dockers, with the WA club likely to hand over multiple first-round selections on top of a substantial salary to secure the 20-year-old.

Should Jackson re-sign with the Demons it'll likely be on a short-term deal, keeping the Dockers - and even Eagles - circling for the seasons ahead.
