I agree with trading down if, when we get to #9, there are reasons to trade down. For example, if we have several players graded the same and it is likley that we will get one of them on a trade down, then why not do it and collect another pick? Can't remeber the last trade down?
Trading to move 1 or 2 pots is usually costly. We traded up for Losman and McCargo, both times reaching to fill positions of need. Both times we struck out.
