Looking at your suggestion has made me really think about the prospect of doing a deal for pick 2 for a player and say pick 8/9. I am not sure if Boak, the player mentioned is as good or better than Trengove but if we assumed he was similar and is a Melbourne boy ( no go home factor ) and we could also get pick 8/9, the deal becomes very interesting.
We would then be getting two players for the pick and effectively three inside the first 8/9.
The other big issue of course is whether that sort of deal is possible.
