"I never would have thought a year ago that Vegas would be a hockey town," Karlsson said. "It's crazy to see that, from month to month, it's been growing. They've seemed to really embrace us and it's a fun place to play."
Karlsson, who had 50 points (18 goals, 32 assists) in 183 NHL games prior to this season, had 78 points to help the expansion Golden Knights to the Pacific Division title, the Stanley Cup Final, and records for wins (51) and points (109) by an NHL team in its inaugural season.
"[I'm] going into the summer motivated," Karlsson said. "I want to try and get better. Obviously, we didn't go all the way this year. That's the goal we have. I'm very hungry to get going and excited for next year."
Five players have scored more goals playing for a team in its inaugural season, and seven have had more points.
Buffalo Sabres center Ryan O'Reilly, 27, and Florida Panthers center Aleksander Barkov, 23, were the other finalists. O'Reilly took one minor penalty in 81 games. Barkov had 14 penalty minutes in 79 games.
