Right now I'd say, if he returns to form and you can find a taker for his entire contract (no cap eating) you move him and use the money you save to upgrade 2nd pairing and 3rd line.
Right now, set to go to UFA:
Zidlicky
Meszaros
Schultz
Tallinder
Robidas
Klesla
Greene
Morris
Niskanen
Hainsey
Stralman
Obviously, Hainsey's ours and we need to re-sign him, and obviously not all these guys are going to make it to UFA. Pittsburgh, Philly, Boston, and even LA are going to have to make some tough decisions on who to keep. I can easily see Mesz or Niskanen ending up here in the offseason, especially since we have Komi coming off the books.
The only thing that makes me think we're not going to be major players on the D UFA front is that we have Faulk, Sekera, Murphy, Bellemore, Harrison, and Liles already. But I honestly think there's a decent chance we could trade someone cost effective like Bellemore at the draft to one of the big spenders in order to bring in one of these guys.
