I'll try and help out here.It just means they didn't prioritise those player like they did for Sinn a couple of drafts later.
The List Management Team will burn a 2nd rounder to move up a few spots to get their guy. They didn't feel a need in that draft.
I love Kossi Pickett but I'm pretty happy with Bergman.
When we traded Dougal to st kilda for pick 18 we also threw in Paddy Ryder and downgraded our pick 10 to their pick 12. Those two picks dropped down 2 places and Pickett and Day were taken with the 2 picks immefiately prior to ours. If we'd kept our original pick in the trade we could have selected either of those players. By being unnecessarily generous in the trade we cost ourselves the opportunity to pick one of those arguably more talented players.
That is what Shultzy is refering to by saying we were bitches in the trade
Edit - re your post that you got in before my response. You acknowleged the trade but seem to have still missed his point
