Berggren is a key player for the Griffins and has established consistency and equity in the lineup.
"What I've liked about him being there is he's got some stability," Yzerman said. "He knows where he's playing tomorrow night, he knows who he's playing with, he knows his role and he's not sitting there, wondering, 'Am I gonna get called up? Am I in the lineup? Am I out of the lineup?' He's playing well and an important player, so I'm happy with him there."
Grand Rapids currently finds itself in a Calder Cup Playoffs spot, which may end up determining Berggren's end-of-season plan.
"I wanna make the playoffs, so I kinda trade that off with maybe seeing him up here," Yzerman said. "But he's certainly improved his play throughout the course of the season and it's definitely something that's on our minds."
Edvinsson is another Swedish prospect who could be a candidate for an NHL audition next season. The blueliner has two goals and 17 assists in 43 games this season for Frölunda in the Swedish Hockey League, where he is teammates with Söderblom. Raymond also played for Frolunda before debuting for the Red Wings on Opening Night this season.
"Simon has done extremely well," Yzerman said. "He's a different player than Moritz Seider, but he's had a real impact for a 19-year-old in a very good league. He's had a tremendous impact in the Swedish league."
