It doesn't really make much sense. They already have Orpik.
If they add a big money D it will be to replace Gonchar.
I think Pitt goes after Hamhuis. And if he's cheap enough, might look at Paul Martin.
The eklund rumour of Pitts being highly in on Volchenkov is interesting. If they let Gonchar go and sign Volchenkov to 4.75 million, then trade Staal and say their second or something for Kabs and Mitchell they get the tough defenseman, the puck moving one, and Salary wise they would be pretty good, as volch takes most of the gonchar money and the kabby Staal salaries wipe eachother out.
hamhuis has become crazy overrated, IMO.
Pittsburgh learned the hard way how much they missed Gill and Scuderi, so they'll probably look to improve the D with similar players if they can.
