I think this is spot on from the few games I have watched in the SHL. He’s overly aggressive on the puck carrier but definitely gets away with it. I think he will quickly learn with better competition though so I’m not worried
Imo the reason he "gets away with it" is because he has the IQ, mobility, size and reach to play this style.
A smaller/weaker D can't be as aggressive, because they're easier to shield the puck from and can't physically outmuscle other players the same way.
A slower D can't be as aggressive because they can get burned easily by faster players.
A dumber D can't be as aggressive because they're going to misread the play and get caught out of position.
etc.
It's the defensive equivalent of looking at Datsyuk and saying "well, he got away with stickhandling through traffic THIS time, but he'll need to adjust".
