I don't think you want to move out of 12. Last year we traded down when Derwin James was there and the rest is history. IMO there will be a guy there who fills a need, will contribute right away and could be a difference maker. No way to predict who will have a good or a bad season, see NOLA last year.I like danno's analysis. Just the thought of projecting covering at least one need through free agency, with a quality player, is something that could make a huge difference in whom they need to draft at #12. It could also free up that pick to trade down, and add a lower 1st, and possibly a second to go with it. That would give us the following picks by rounds. 2,2,1,2,1,2,1. If you can pop in another 3rd through some kind of a deal along the way, you would have a pretty good draft going in.
Another way to look at it would be to trade our #12 pick to someone you know is going to have a horrible season for their 2nd and 4th this year, along with their 1st next year. Stock the shelves over two years, not try to do it in one.
