Adelaide have traded its pick 4 to GWS for pick 6 and a future first-round pick.
The move will likely allow the Giants to pick a player in the open pool before a bid comes to highly-rated academy prospect Tom Green.
The Demons could place on a bid on Green with pick 3 but are also keen on using their selection on ruckman Luke Jackson.
GWS are likely eyeing speedy halfback Lachie Ash, rebounding defender Hayden Young and midfielder Sam Flanders with their pick 4.
The Swans could also bid on Green with pick 5, who is a Canberra local.
The trade with Adelaide means GWS will likely be able to get ‘inside’ the bid for Green.
