On his first shift, Dahlin skated down the left wing before shooting just wide of the right post. He also did a splendid job quarterbacking Buffalo's power play, settling pucks with ease and hitting teammates with precision passes.
"An effective power play is one that moves the puck fast and gets a lot of shots on net," Dahlin said.
He brought fans to their feet when he leveled Devils forward Ryan Schmelzer with a solid body check along the boards at center ice.
The edge in Dahlin's game shouldn't come as a surprise. He had 30 hits and 36 blocked shots in 41 games for Frolunda of the Swedish Hockey League the past two seasons.
"That's the way he should play; I expect every player to play that way," Taylor said.
Dahlin, 18, became the highest scoring under-18 defenseman in the history of the SHL, the country's top professional league, with 23 points (eight goals, 15 assists) in two full seasons. He was named best defenseman at the 2018 IIHF World Junior Championship, with six assists for Sweden, and was the youngest player by seven years on his country's roster for the 2018 PyeongChang Olympics.
