The Norris Trophy winner for the 2022-2023 season, Erik Karlsson, has been in the center of a lot of trade rumors in the last few seasons. Everyobody knows he wants out of San Jose and it's only a matter of time before he changes team.
In Carolina, we can't even imagine the damage he could do. Alongside Brent Burns or Jaccob Slavin, the Canes' defense would be one of the toughest to play against in the whole league.
In Toronto, just visualize the power play. He'd fit extremely well. Treliving will have to show his magic if he wants to make a deal, but he has the assets. He might need to break the Core Four, but wouldn't it be worth it to get Karlsson?
As for Seattle, they shown that after only two seasons in the NHL, they need to be taken seriously. Their team has a lot of depth and will probably look to go firther in the playoffs going into next season.
