Not a good comparison IMO. Canes fans would liken Pashin to Sergei Tolchinsky. Both are small Russian wingers who have been in our system. Both flashy. I think both will be career KHLers.The Russian Cole Caufield... but much weaker.
His window is closed. He will never reach the level sufficient to play in the NHL.
Becoming a good KHL player will already be quite a challenge.
