If Staal were traded, Id like to see Scuderi here. Hell, if Del Zotto is moved, I'd like to see Scuderi here. Great bottom-pairing defenseman, excellent penalty killer, tough as nails, and a veteran with two cup rings.
Now, I'd be intrigued as to what Staal could return. I could honestly see #5 for Staal, it makes sense; not because his name is Staal and because it's the Hurricanes, it's because the Rangers effectively clear cap space with this move and also secure an asset that is most likely NHL ready next year in a third/fourth line role (READ: Sean Monahan, Valeri Nichuskin, potentially Elias Lindholm). The Hurricanes also get what they're looking for in a top-notch defenseman. Could probably get Caroline to throw something else in there, as well.
