With that move by CLB for Duchene, you have to think that pulls Panarin off the market, which hopefully means the Kings are now in a stronger sell position with remaining buyers. Remove Bobrovsky and it clears up scenarios even more. Here are the teams that are still buyers who I think need to make some kind of depth move to upgrade for the playoffs.
San Jose
Vegas
Calgary
Dallas
Nashville
Winnipeg
Boston
Montreal
Tampa
Islanders
The best possible players to trade are Carter and Kovalchuk. I could see teams like Boston and Dallas as ideal trading partners for either of those players.
