I do think Heiskanen has some offensive upside as shown by Team Finland who decided to use him on the PP instead of Juuso Valimaki at the WJC. But I also really liked the Vlasic/McDonagh projection. Both have offensive skills but are more focused on the defensive side of things and won't produce huge points (especially without PP time). McDonagh had 33 and 34 points these past 2 years when he didn't have this much PP time.
