Agree. I know some Buffalo fans think that they're set at D (more or less), but Andy would provide them with sorely needed leadership.
Whether there would be adds by either side is open to debate. The point is that I am sure something would be accomplished.
Buffalo has picks coming out of the ying-yang and a farm team brimming with prospects. I am not so sure they would be interested in more picks, but having more defensive depth, i.e. Miromanov or Bean, might enter in to the discussion.
Perhaps a larger trade could be had as well given that they have the 9th pick overall.
