How acquired: Selected with No. 1 pick in 2018 NHL Draft
Last season: Frolunda (SHL): 41 GP, 7-13-20
Dahlin (6-foot-2, 181 pounds) could start the season on the No. 1 defense pair with Rasmus Ristolainen. The 18-year-old, who is a left-handed shot, set a Swedish Hockey League record for points in a season by an under-18 defenseman. He was named the best defenseman at the 2018 IIHF World Junior Championship when he had six assists in seven games, and he was the youngest player for Sweden at the 2018 PyeongChang Olympics.
"Just how he shifts back and forth from one side to the other side," said Chris Taylor, coach of Rochester in the American Hockey League affiliate, who ran Buffalo's development camp. "He can stop laterally, his stride, his passing is crisp like an NHL player. Receiving passes, you probably see a lot of times pucks bouncing off of people's sticks. It didn't bounce off his stick. He's just one of those guys, you can tell."
