The main issue at this point remains that Erik Karlsson carries a $11.5M cap hit until 2027 and the Oilers currently have $0 under the cap space.
It's been stated that the Oilers would certainly be open to move support players like Yamamoto, Puljujarvi or even Tyson Barrie, if it meant acquiring Karlsson.
