There isn’t much to say about Seider that has not already been said. Seider has absolutely dominated the Swedish Hockey League this year. Elite Prospects recently gave Seider their 2021 SHL junior player of the year award, reinforcing the narrative of Seider’s domination.
Seider grew leaps and bounds in his development with Rogle BK, showcasing his physicality and heavily improving his offensive game. He notched 28 points in 41 games played (7 goals 21 assists), leading all under 20 defenseman in the league (By the way, in second is another Detroit prospect, Albert Johansson). But if you try to take away Seider’s offensive game, he’ll just knock you to your feet. Nearly every player that dared to test him ended up sideways on the ice.
There is certainly a level gap between the NHL and the SHL, but with the complete dominance Seider showed in his time with Rogle BK, there should not be any concern about translation of skill. Seider is Detroit’s most pro-ready prospect, and will almost certainly become a mainstay on the Red Wing’s roster, probably on day one.
