Doesn't Vegas already have too many defensemen? I wouldn't think that'd be a need for them.
As far as Eakin goes, I just am not a huge fan of his. He's solid defensively a pretty good on face offs, but offensively I'd hope for better. I'd rather gamble on Linberg.
Yes they have too many, but the following are number 6-8's that are pending UFA's:
Sbisa, Stoner, Garrison, and McNabb (probably a 4-5), and Engo (likely re-signed due to Vegas being "home"). If those 4 walk this summer or are dealt at the deadline, they will be left with:
Schmidt (UFA after 18-19)
Merrill - RFA
Miller - RFA
Engo - UFA but likely re-signed
Theodore - RFA
Hunt
Schmidt, Miller, and Theodore are only top 4 guys. Cole would make them better short term and give them some certainty long term. He'd be a 2nd pairing guy and one with Cup experience.
What I don't know is why GMGM would move any of their centers to sign a guy long term on D. I can't see JR coveting Lindberg enough to move Cole and I can't see GMGM wanting to move either of Karlsson or Haula for a 4-5 dman.
That leaves Eakin and his contract structure is a tough fit for the Pens.
