I would also tend to think that this is pretty much a pipedream. It's not as if we have many tradeable assets right now. Our prospects are pretty weak, and most of the players that could actually get some attention in a trade have NTC's.
That said, if I had the opportunity to trade some of our D(core or otherwise) for a legitimate scoring forward, I would jump at the chance. While we should have some cap space next year with contracts coming up for Naslund and Morrison, the FA market isn't going to be that hot. That being the case there may be some wisdom in making a trade from a position of strength to compensate for a position of weakness.
If we were to lose a core D or two and in the process make this into a team that has the potential of putting the puck in the net so be it. With guys like Edler and Bourdon showing that they are able to make the next step up and with prospects like, Rahimi, McIver and Coulombe still in the ranks, why not actually use the depth instead of waiting for offense to magically develop from inside the organization. That is a ship that just isn't going to dock anywhere in the near future. We have enough pluggers in our system to have stopped New Orleans from sinking, but of blueship forward prospects I see nary a one. Thus if we had the option to trade talent for talent and boost our offense there would be no hessitation on my part.
