He missed time due to injury not scratch since going to Sochi.Michkov failed to crack a KHL lineup this season. Made a weaker KHL team now after getting loaned but he has been healthy scratched by Sochi as well.
Button is a joke but Michkov may very well just not be as good as many people assumed.
He has the highest points, and PPG of any D+1 player in KHL history. In fact he would be 6th (ahead of Panarin) in points and 4th in PPG (ahead of Kuznetsov and behind Kaprizov) if you include D+2 players in that also.
Holding it against him because he didnt crack SKAs lineup is kind of funny. He needs a top 6 role to develop and SKA is the best team in the league. He is 18.
