This will be one of the most corrupt trades if this gets approved. Trading in a player and receiving higher picks has never been done before.
This one in 2015 saw GWS dump 4 salaries and send what turned out to be pick 10(H MacKay) to the Blues in return for what turned out to be pick 33(Mitch Hibberd) and what turned out to be pick 17(Jarrod Berry) in the then future 2016 draft.
So the Blues turned picks 17 and 33 into Harry Mackay by taking on 4 spuds on silly wages. They are still trying to wash the last one through their list now.
