First Start by entering season mode and choosing the side you want (cheat works best id it is a bottom side like st kilda or collingwood) de-list 5 of your players and continue until you reach the actual game quit straight away and you will start at the menu again. Then choose the team that you want a player from (eg Brisbane and Michael Voss) then de-list the player you want and continue until you reach the game quit again and when you reach the main menu choose season mode again and chose your original side and draft the de-listed player.
