His KHL points per game is currently 1.23. He’s maintained a very similar points per game over every single KHL season of his career since he became a member of St. Petersburg.
Using the KHL->NHL conversion rate multiplier of 0.73, his NHL estimated points per game would be roughly 0.9. So, if he played an 82 game season, we can estimate that he would score roughly 70 points. Which sounds about right, although I’ll admit I haven’t watched him outside the Olympics, where he was still very impressive.
