You must understand that Anisimov was merely a fourth liner at the RSL level for the vast majority of the season. Only towards the end of the regular season as well as the playoffs did he step it up and begin to make more of a contribution to his team. Am I prepared to say that he is NHL ready on account of this last stretch? No, not really. It was a big step in his development, but even then, he was overshadowed a number of fellow NHL prospects on Lokomotiv. He is one of the more promising prospects in Russia, but not quite ready for the NHL yet.
As for Volkov, it was hard to decide between him and Mirnov for the last spot in my top twenty. He is strong on the puck, has decent offensive instincts, is very responsible defensively, and versatile enough to play center or wing. All in all, he could be a very good bottom-6 player.
