The 18-year-old defenseman was taken with the No. 1 pick in the 2018 NHL Draft after he had 20 points (seven goals, 13 assists) in 41 games with Frolunda of the Swedish Hockey League last season. Dahlin's 23 points (eight goals, 15 assists) in 67 regular-season games over two seasons were the most for an under-18 defenseman in the history of Sweden's top league.
"It's been a dream since I was a little kid," Dahlin said at the draft in Dallas on June 22. "It's been a long wait and you can't really plan anything, but like finally today I can plan my future and I love to call my new town Buffalo."
