I just reviewed the last 8 years of KHL scoring, there are few top prospects among the leaders (probably b/c few excel at 18-19, and come over when they're NHL ready around 20, so someone as talented as Michkov playing 3 years in the KHL is rare). The KHL is a veteran dominated league, even more than the SHL and much more than the AHL (which is a developmental league that limits how many veterans can play).
In NA, a player as talented as Michkov would probably play one more season in the CHL and then the NHL at 19. Might even jump directly to the NHL, but would probably struggle for a year or two (see Hughes, etc).
I'm skeptical that any poster labelled "GodKingMichkov" is an objective observer.
Though I agree that if Michkov is for real, he should be a threat for 100 points his first NHL season, at 21-22 years old, with 3 years of experience playing against men, albeit less talented men than the NHL (Lehtera is an object lesson, a below replacement level NHL player, from age 32-34, 137g 34-79 113 in the KHL, then at 35, 57g 11-46 57 in Liiga), he'll have time to fill out and be ready for the rigors of a NHL season (82 games plus hopefully the playoffs).
