Did you get any grip of why he didn't play well? Was he just ineffective? Was he frustrated? Was he tired? Sucked?
Another problem is, at which place did he play this season that hasn't been small sample size?

All are small sample sizes. He scored a bunch at the Hlinka but also the 4 nations. He moved from Moscow and to St. P this season and played a little in the KHL, a little in the MHL, a little in the VHL, a little for the U20 national team and a little for the U18 team. How was he received as a Moscow kid on that MHL team, did he get pucks to work with etc?
I am not giving this kid a pass and your report that he didn't play well in the MHL definitely means more to me than the stats alone. I've also seen first hand how frustrated he got at the WJCs. You know that typical childish frustration where you show up at first and play great, have a little bad luck and starts to bang your stick, then it seems like the kid has the most bad luck in the world and comes to the bench in pain every other shift "crying" because they got hit in the foot by a puck and what not.
I've gone from acknowledging some issues with the kid 'but you can't just pass on the kid no matter how many grey hairs it would give you if you drafted him really high', to thinking that most players in the top 12-13 (rounded off buy guys like Caufield, Boldy, Dach, Newhook and co in most rankings) qualifies for being put toe to toe with this kid.
