THE AFL has made its next move in attempting to remove a complex loophole from the academy and father-son bidding system in the draft.

In last year's NAB AFL Draft, the first under the new system, clubs were able to trade backwards to boost their available points.

To do this clubs traded in draft picks that were never actually intended to be used to select a player, instead using them to simply bank points for academy and father-son selections.

One option under consideration is to scrap the ability to trade backwards for points or 'hidden picks', by making a traded draft pick equate to an actual vacancy on a club's playing list.  

Also up for discussion is whether clubs should receive a discount when recruiting a player from their own academy.

AFL general counsel Andrew Dillon wrote to all 18 clubs on Friday seeking feedback on the system.

He's requested they respond by July 17.  

Changes could be in place for in time for this year's exchange period and draft process.
