Apparently the Devils are looking to trade a defenseman for a forward. The Kings might be able to make that happen. Some people were mentioning Volchenkov or Tallinder. Trading for Volchenkov would pretty much mean not re-signing Scuderi, though.
Someone also suggested Mike Weber for Richardson. That sounded like a good deal. Weber was second on the Sabres in hits last year. Sounds like he's a physical, defensive-minded third-pairing guy. Could be a good replacement.
