Anaheim says nope

Sorry bud. I don’t think karlsson is ever movable on that deal. He’s retiring a shark

Anaheim doesn't consider that. Add multiple 1sts and amazing prospects and that might not get it done

Man you're making a tough ask to get rid of Karlsson at all. Especially with the cap situation Anaheim was/is in, I sincerely doubt Anaheim takes him on. Add in Donato, 2 1sts, a 2nd and a 4th and MAYBE you have something but at $11.5 million for another 6 years, after the nose-dive his production took, that's the LAST thing the Ducks need, yet another underperforming offensive defenseman. They already have Manson, Fowler and Lindholm to deal with.

I hate telling you this, but even if you sell him dirt cheap, that contract is such an immediate turn-off that you're unlikely to ever trade him unless he puts up Norris numbers this season. The only way Karlsson doesn't retire a Shark is if you buy him out, and if that IS what they do, that's still 4 years away. And to have the cap space to pull that off, you have to trade both Burns AND Vlasic, which itself would be difficult (but eons more feasible). You could absolutely package Burns with a 2nd and send him to Anaheim for a 6th or 7th to free up space, but Karlsson's a different animal dude. He's 30 with a rough injury history, the 2nd largest cap hit in the entire league for a player that hasn't had elite offensive production in years and defensive metrics among the worst of top pairing defensemen in the league, you could offer him for future considerations 1 for 1 and you'd STILL have trouble selling him off unless you retain a lot of salary.

The ONLY feasible trade I can think of is Karlsson and a 1st for P.K. Subban. At this point the Sharks management would be foolish to worry about the Karlsson contract. They'd better be more focussed on somehow signing Hertl and Meier on decent deals. As opposed to that ridiculous 8 year contract they gave to... Logan Couture? If you thought the buyer's remorse would end with Kane, Karlsson, Vlasic and Burns you my friend couldn't be more wrong. That deal will come back just as hard, if not worse.

He might get bought out

I don’t think they can even think of that for another 4 years. With 2 years left on his deal, maybe then
