He is arguably the Wings best D-man when the season starts. Yes that speaks to who is on the team and some of the problems, but you don't want to healthy scratch Mo Seider for some of the other guys on this team. He is flat out dominating the SHL after being a #1 D-man in the AHL last year logging upwards of 25 minutes a night on occasions for the Griffins. His planned nine game treatment was actually supposed to take place in late March of last season.
It also helps that the only real question on Seider seem to be trending towards how much offense he has. To date he has been exceptional in his own end, great skating, smooth, physical dominate at times with the pros as well. He has also played 3 pro seasons, he isn't really your press box learn to see the pro game candidate. He will barring injury more than likely go directly from the SHL to the NHL to finish his season.
I do expect him to go through some rookie struggles. However he is too physically gifted and is dominating at his current levels, he is going to be pulled up as a result and because of the team he is joining has plenty of opportunity to earn ice time and given how he has played since the spring of his draft year I just don't see this being the transition in terms of lots of press box. Kind of like when Larkin played a lot as a 19 year old, I expect Seider to do the same.
