As a fan of Swedish former Red Wings like Nicklas Lidstrom, Henrik Zetterberg, Niklas Kronwall, Tomas Holmstrom and Johan Franzen, Detroit was Berggren's favorite NHL team as a child, and he was thrilled to be drafted by the Wings and have a chance to follow in the footsteps of his famed countrymen.
"Detroit was my favorite team growing up," Berggren said after he was drafted. "They had all the Swedes on the roster. I'm excited."
But the road to the NHL has been an eventful one for the 5-foot-10, 181-pound winger.
After tying for the scoring lead in the Swedish junior league with 57 points in 38 games in 2017-18, Berggren suffered separate back and shoulder injuries the last two seasons, combining for 15 points in just 40 games played in that span.

The swift-scoring winger bounced back, though, and enjoyed a breakout campaign for his Skelleftea AIK club in 2020-21, earning 45 points (12 goals, 33 assists) in 49 games and adding four points in 12 postseason contests to lead his team to the SHL semifinals.
Berggren's 45-point output this past season was good for a sixth-place tie among SHL skaters, and he became just the 13th player in SHL history at age 20 or younger to earn at least 40 points in a single season.
Red Wings director of player development Shawn Horcoff said Berggren has developed a lot of mental toughness through rehabbing his injuries and he's polished the raw skills that enticed the Wings when they drafted him three years ago.
"He's a guy who's faced a lot of adversity with injuries the last couple years," Horcoff said in October. "These aren't injuries that are easy to come back from. To his credit, going through that, it's done two things - it's made him realize what he needs to work on, and it's also given him time to work on those deficiencies.
"He was a guy we drafted who was very raw in terms of his physical development. I think the last couple of years, the amount of time he's been able to spend in the gym and off the ice has helped him in that area."
