Trades involving draft picks in an active draft.
Once the trade is agreed upon GM2 tells GM1 he wants him to select player X when the pick is up. That players rights are then listed in the trade instead of the actual pick. This will take waiting for approval of the trade with the draft pick out of the mix, allowing an already slow draft to have a bit more flow.
I hope that makes sense I have been enjoying an old fashioned or 3.
