Blue chipper generally means they are going to have an immediate impact to the team and is a can't miss. Tolvanen was considered a blue chip prospect by the loose definition of being at the top of the league and most thought he would have some immediate impact to the team. I wouldn't be surprised if Tolvanen never makes it to the NHL as he seems to still be struggling. I don't see Kap having an immediate impact to the team and he is definitely not a can't miss prospect given how wonky KHL players have had translating over to the NHL.
