According to TSN insider Pierre LeBrun, the Sharks and Oilers were not able to come to an agreement on the financial aspects of a potential trade. However, both sides may revisit the idea during the offseason when they have more financial flexibility. LeBrun explained
The Sharks are currently rebuilding and retooling their team, so it is likely that they will continue to consider trade options for Karlsson during the offseason. The biggest question for them will be how much of Karlsson's remaining contract they are willing to retain in order to facilitate a trade. LeBrun believes that the Sharks might have to eat up to 50% of his deal if they want to make a trade happen.
Despite Karlsson's excellent play this season, there is always the potential for his contract to become a burden as he ages. As a result, the Oilers are hesitant to take on a 32-year-old defenseman with a long-term, $11.5 million annual salary. Nevertheless, if the Sharks want to rebuild and re-stock their personnel, they should do everything they can to facilitate a deal with Karlsson.
