SJ would save under $4k...if that makes a difference to them I would think that means trouble for the organization.
Only other thing I can think is Burish, but that seems unlikely, and if he is ready to play they have are about to have a huge problem since Torres is a few away as well.
Sharks would be smart to trade a couple players now before they end up having to do so out of desperation. Kennedy would be my pick as Wingels has made him pretty expendable and I'd rather keep Wingels of the two. Sharks also have to move a defensemen if they plan to bring one in, ideally Stuart, but more likely Irwin or Demers. Havlat is another easy answer, but has little to no value.
I would love the Sharks to retain everyone, but it just isn't possible at this point. When healthy the Sharks just have way too many players and too much salary. They need some breathing room, and they have the luxury of quite a few waivable NHL capable players to call up (Nieto, Hamilton, Petrecki, Doherty, Acolotse, Tennyson).
Right now this is the healthy list of non-waivable Forwards (for various reasons), bolded are the guys I think the Sharks will see as exendable:
Thornton
Burns
Hertl (way too talented to waive)
Couture
Pavelski
Marleau
Wingels
Havlat
Torres
Kennedy
Sheppard
Desjardins
McCarthy
Brown
Burish
That is 15 essentially unwaivable forwards. The only guys who are 'bad enough' to actually possible clear or are so worthless the Sharks wouldn't care if they were claimed is McCarthy (and I bet he'd get claimed).
Now onto defense, where we know we actually need help you have:
Boyle
Irwin
Vlasic
Braun
Demers
Stuart
Hannan
None of them are going to be waived, and space would have to be made. Someone has to go. Irwin probably has very minimal value, Demers probably has less value than he is worth to the team. Stuart would be the best guy to move, but that might not be possible.
If I was the Sharks I would be trying to get rid of Kennedy, one of Burish/Brown, and Stuart in a deal to bring back a capable left side offensive d-man.
