He's a shut down D man and the sens havent had the most luck in developing those... Well anything that amounts to much more than a borderline number 6/waiver player...
However other than his style its probably because not many posters watch a ton of the SHL id guess.
Other than the WJC thats all I have had the opportunity to see him, is he a strong player at the pro level? Do you think he could be a number 4 shut down type?
I have seen quite a bit of him watching the SHL.
I think for sure he could end up a shut-down #4-5 Dman... he has performed very well in the SHL vs men this season. Being his age and getting the ~17-18 mins a night he does on a pretty decent SHL team is nothing to sneer at. Especially when he quite often matches up vs the opponents top sixes.
If he reaches his potential he could be a modern day prototypical shut-down guy. Solid skating ability and a fair outlet pass combined with very good defensive tools, a physical side and IQ.
He knows his role and plays within his skill-set too... does not try and do anything fancy once he separates man from puck his go-to is getting that puck to the tape of team-mate forward quickly and effectively to help transition. I think that is a big thing for defensive defenseman... knowing your game and limits is key.
I imagine actually if he reaches his potential he would be playing a similar role in the NHL as he actually does right now on DIF.
He also played a couple of games for Sweden's mens team on the EHT this year... now he is not one of Sweden's best 6, or even ~10, defensemen in Europe, but it shows you that the National team think highly of him already.
