According to capfriendly the following is expiring:
5,000,000 - Filppula
3,625,000 - Read
1,000,000 - Oduya
0,975,000 - Manning
2,000,000 - Mrazek
1,500,000 - Umberger
14,100,000 in space opening up...
That leaves:
Giroux
Voracek
Lehtera
Couturier
Simmonds
Weise
Raffl
Weal
Laughton
Patrick
Lindblom
Konecny
Leier
MacDonald
Gostisbehere
Gudas
Hagg
Provorov
Sanheim
Elliot
Neuvirth
In regards to bad contracts, I would consider the following to be the ones the team would love to move, but will be unlikely able to:
Voracek
Lehtera
Weise
Raffl
MacDonald
The following will be prime trade bait (yes, I know a lot of people here do not like these guys, but they probably are desirable to other teams):
Simmonds
Weal
Gudas
