Last night's game shows you that they can hang with the big guns. They need D and G upgrades.
Dump Chiarot, Petry and Holl. Then let Reimer walk. You have to move on from Husso, he injured himself AGAIN! You have to buyout his last year of his contract.

They need to upgrade G, period. Whether that's a trade or UFA. They could try to get Samsonov or Kahkonen as UFA.
The D needs upgrading the most! Edvinsson is here to stay. Re-sign Ghost if you want, but you still need 2 more if you dump the three I mentioned. Go all in to acquire a 28 something (or younger) D. If you can steal Andersson from Calgary, or if you can get Chychrun. I'd start with Berggren and a protected 1st for either of them. Then you could go UFA for another, or a lessor trade. I mentioned Fowler before. You could do Veleno, UFA rights to Sprong, young D (like McIssac or Viro) or a 2nd round pick. Anaheim has tons of cap, maybe they could retain 50% on his last 2 years if the contract.
Up front Kane is a must. Just pay the man. Then you'll need to replace Veleno and Sprong. There's plenty of players out there that would fit, it's just trying to get them in under the cap.
