Rakell - Has been playing much better this year but not rewarded for it. Seems to have developed chemistry with Comtois. Available but the ducks can wait until next year if they want. Even if they wait, he likely still gets a first round pick next year if traded at the deadline or in the offseason. Given the quarantine rules and all the teams with cap issues - all of which make it tought to make a trade - it might be better to wait.
Fowler - not likely to be traded. Aside from the fact the ducks are thin on veteran defense, Fowler can only be traded to 4 teams he picks. Hard to trade. And I think they want him around to mentor Drysdale and as a hedge against Lindholm leaving.
Silf - has been a bit disappointing this year, but he contributes in a lot of ways that are not obvious. Incredibly versatile and a streaky goal scorer. Ducks management seems to love him and he's a bit overpaid. But certainly available in the right deal.
Henrique - clearly available. He's struggled this year and the contract is starting to look bad. Not sure what he'd return.
Steel - not available unless its for an elite young player (for example, as part of a package to get PLD before he was traded).
Jones - available in the right deal. He's adequate and brings good energy, but easily replaceable since the ducks have logjam of bottom 6 forwards.
