I don't see why Carolina would make Pesce available. Burns replaces Deangelo, they still need Pesce.
But the Canes still make the most sense to me with a deal centered around Necas or Morrow, and they have the space to fit Miller's extension (but Canes fans are adamant that is simply not the type of move their management team would make, which is fair).
Caps are also a good fit if Backstrom is done.
Isles won't give up Dobson and they have nothing else we want, so there's no fit there. Pens already traded away what we may have wanted, but I'm still of the mind that if we wanted Marino he would have been a Canuck a long time ago.
