Those are different kinds of targets, though. I highly doubt Risto is available and Larsson turned it on in the second half and still has the sheen of a top pick, although he might be attainable considering they're loaded with young defense talent and barren up front - a mirror image of our trade needs. Either way, those guys are expected to break out. I was thinking more along the lines of guys like Brodie, Vatanen, Sekera - guys that weren't really expected to be as good as they are now.
I realize what I'm asking for here is something like pulling a rabbit out of a hat, but these aren't huge risks either, considering what we have on our roster. If we landed any of the guys I mentioned (Ellis et al), they wouldn't cost the moon and they are, at the very least, as solid as our bottom-pairing guys. Its a low-risk, high-reward move. At the very least, it would mean bringing in non-Red Wings defense products, which probably can't hurt at this point.
