How old is Fyfe now? Possible long term fitness issues? How many more full seasons will the Dockers get out him? Seriously doubt that the club would receive 2 top draft picks for him. That boat has sailed.
Apart from Franklin-Hawthorn and possibly Judd-West Coast, both of whom had ample second, third, even fourth string coverage already, when has trading on super players in their prime ever benefited the former club with a premiership winning replacement?
