I wouldGood to see him turning it on late in the tournament to help secure the win and birth into next round but I didn't have many worries he would have trouble against the teens.
For me, he needs to come over to NA next year, his development in KHL has been underwhelming. He's on the cusp of being an untouchable for me but right now, sits outside it and I would move him in a package, if for the right piece on D. Hopefully he's a good replacement for Dadonov in a few years if he keeps improving.
Leave him in Europe. They seem to develope better over there and he needs more physical development without the worry of adjusting to coming overseas.
