Based on the analytic of pNHLe, or Projected NHL Equivalency, Grebyonkin is on track to become a similar player to Jakub Vrana. However, Grebyonkin started his season playing less than two minutes a night with Magnitogorsk, and thus his equivalency is on the low side.
It is safe to say that the Maple Leafs may have a superstar on their hands across the pond!
