I'm not worried about Kylington at all. His skating and puckhandling are already elite and he's grown so much defensively in the last year.
Yes, he makes lots of risky plays and sometimes that leads to chances against, but I'd rather him be confident enough to make those plays than do what 90% of all other hockey players do and be too afraid to take those same risks because they're afraid they'll get benched by the coach.
Kylington could very easily stop making those plays and look just like every other D-man out there. But I'm glad he doesn't, because it makes for fun and exciting hockey. Coaches have made hockey so dull these days that it gets boring to watch sometimes. But players like Kylington are what provide hope for the future. They're the players who are confident enough in their abilities (even if lots of his moves don't work out) that they make the game exciting.
He'll definitely take some of those risky plays he makes out of his game as he continues to progress but for the most part, I'm very happy he hasn't completely changed his game and shifted to playing a typical boring style that is so common in today's D-men.
Also, I think people have been extra negative on Kylington these first two games because he gets the most ice time among all Sweden players and combine that with the way he plays the game, it's IMPOSSIBLE not to notice him so it's easy to pick him apart considering a player who plays as much as he does is bound to make some mistakes.
