He needs to pass one of Hischier, Heiskanen, Pettersson, Makar or Tolvanen to do that. Then you have guys like Patrick, Mittelstadt, Vilardi, Chytil etc. to battle for top 10 spots, and then you have the inevitable later round steals. This is a bold statement to make.
If you go beyond hockeydb and eliteprospects, you will see that Liljegren is playing on a much stronger team than any of the D+1 comparables, and his competition is on the lower end. His 5v5 production is also quite low compared to others, especially his primary point production. Per/60 rates are also low.
