Karlsson was the most magical story amid the most magical story in sports last season.
After the Golden Knights claimed him from the Columbus Blue Jackets in the 2017 NHL Expansion Draft, he had 43 goals, 34 more than ever before in the NHL; 35 assists, 16 more than ever before; and 78 points, 53 more than ever before. He was plus-49, first in the League, and won the Lady Byng Trophy for sportsmanship and performance.
He was a big reason the Vegas shattered records for first-year teams, finished fifth in the NHL standings and advanced to the Stanley Cup Final, losing to the Washington Capitals in five games.
But even then, the question was if it was too good to be true. How did a player who had never scored more than nine goals in a season suddenly score 43, third in the NHL, even if he got the chance to be a No. 1 center for the first time? His shooting percentage was 23.4, 15.7 higher than his previous career average. No one else with at least 20 goals was higher than 19.2.
Late last season, he said, "One year doesn't make a career, you know? I will for sure be hungry next year to prove that I can do it again, both for myself and to other people."
In the offseason, after signing a one-year, $5.25 million contract as a restricted free agent, he said, "It's me betting on myself a little. … I believe I can have another productive year, show that last season was no fluke and earn something long-term."
Well, regression has struck, as it has for some of his teammates -- particularly his usual linemates, Jonathan Marchessault and Reilly Smith -- and Vegas as a whole. Through 55 games, Karlsson has 16 goals, 17 assists and 33 points, and he's minus-8. His assist Tuesday was his second in 14 games; he has one goal in the same span. He's averaging 2.05 shots per game, not far off the 2.24 he averaged last season, but his shooting percentage has dropped to 14.2.
"Maybe I didn't expect myself to score 43 goals again," Karlsson said. "It's only really [Capitals forward Alex] Ovechkin that can keep scoring so many goals every year. But obviously I'd like to have more points by now."
