Not many teams that can take on Palat's full contract. He has a full NTC for this season. I can't see him waiving to go to a team that can fit him (Devils, Kings, Predators, Senators, Wings). Jackets, Panthers, Hawks won't have room once they sign their RFAs and get to a full roster. There's also several teams that have to purge some cap.
Killorn only has a modified NTC so he has a higher probability of being traded but even then it's a 16 team no trade list.... and i don't think Devils, Kings, Predators, Senators, Wings will be on the list of where he can be traded to.
There's also still good UFAs that can be had for free (Hoffman, Duclair, Soderberg, Granlund, etc). At this point, with how few teams have enough capspace to take on these caphits and with the players having trade protections limiting where they can be sent, i can't see them costing more than future considerations and will likely end up costing Tampa something.
