These are very respectable numbers, considering the league he plays in, correct?
well... let's see...
Metallurg Magnitogorsk is currently second in the Superleague. The franchise's best goalscorer is Kudermetov with eight G, second best Gusmanov with seven G, Pestunov and Osipov are tied for the third position with six. Take in account that Pestunov is only 18 (will be nineteen on January 22). He's a regular starter, played 24 out of 25.
But on the other hand all Metallurg goals are more or less evenly spread across the roster. They don't have anyone like Mozyakin who's currently leading the league with 14 G. Dunno if it's bad or good, will see later I suppose when the playoffs start.
Unfortunately I've been unable to catch the broadcast of any Metallurg game so far this season so I can make my judgement only by the short snippets of the game they show in the news. Once I see them play I hope I'll be able to give you more or less comprehensive account on Pestunov.
