Yeah you're right he could do the job (but he lacked consistency defensively during his career), honestly IMO the team should upgrade the D by getting someone better than Gorges/Diaz and then by trading one of them.
Looking at the list (I'm looking at guys 33 and younger) :
Pitkanen
Orpik
Meszaros (Not a top 4 anymore)
Nick Schultz
Girardi (the priority)
Quincey (Maybe ?)
Klesla (injuried alot, seems like he's not a top 4 anymore)
Nikitin (Having a down season, but he could be an interesting choice)
Hainsey (Inconsistent and soft)
Gilbert
MacDonald
Some of these guys will sign with their team, so sadly it's not a good year to find a top 4 through the UFA market. Maybe a trade could be more interesting.
Also they have to either resign Murray as Physical depth or sign a guy with the similar role IMO :
Greene
Stoner
Fistric
Engelland
Stuart
Nikitin, MacDonald, and Gilbert are guys I think Bergevin will be looking to for signing. I think they will come at a lesser paid group. Not looking for huge $$$ amounts but just under the big money guys. It is hard to gauge what they will get because it seems more and more dman are going to eventually go off the market, ex. Phaneuf. Teams will follow the same trend when they see the upcoming market for dman closer to end of the playoffs.
Fistric, I personally would of love to have him a season or two ago, but I would prefer to bring in a guy like Pateryn over him.
I am very interested in Stuart. He could play a bottom pairing role with the Habs and would be part of the leadership group I find if he came here. Another Habs poster said Jets fans absolutely dislike the guy. I don't know if that's the case because the whole Jets squad has been inconsistent. He suggested having Pateryn and Tinordi fulltime over signing him. I find its ridiculous as he has a lot of experience and is physical.
Greene he will probably be in the more expensive dman group if he makes it to the market and Bergevin isn't in a position to spend ridiculously.
I think this would be something our squad will look like next year.
