Following Thursday's trade to the San Jose Sharks, the Swedish sensation will now be taking his show to the Bay Area. Still, it's not too early to revisit some of his finest moments suiting up as a Senator:
The Edmonton Oilers are known for scoring goals, but it was all Karlsson on this play, as the two-time Norris Trophy winner went end to end through a group of Oilers and fired a knuckleball by Oilers netminder Ben Scrivens.
After Karlsson missed nearly the entire 2012-13 campaign with an Achilles injury, he'd have been forgiven for playing at a slower pace in the playoffs. But that wasn't the case in the opening round against the Montreal Canadiens, thanks to Karlsson's ability to simply take over shifts. The Senators went on to beat the favored Canadiens in five games.
Typically reserved for the billiards lounge, this crafty bank shot stretched nearly the entire ice to set up veteran forward Milan Michalek. The winger scored a nifty goal in his own right, but the play will be remembered for Karlsson's wizardry.
Karlsson played through the 2017 postseason on a fractured heel, but the injury seemingly didn't take away from his ability to pull off the incredible. Here, he took the Boston Bruins for a ride before setting up Derick Brassard for a magnificent game-tying goal in Game 2.
Dumping the two-line pass rule opened up more creative avenues for puck-moving defensemen. Karlsson took it to the next level on this play with a Hail Mary setup that landed right on the tape for former teammate Mike Hoffman.
