I think you May have a point if you anticipate Demco will not be very good but in general a good goalie is huge I mean think about it they are on the ice for 60 minutes per game that’s three times more than the best forward on the team so it’s fair to say they have thrice the impact so wouldn’t you say that your team would get better if you had added three all star level forwards? The idea that we are getting from the scouting projection community is that Demko will be an all star goaltender.
Alexandre Daigle was considered generational talent.
You're projecting prospects way ahead of the reveal on NHL ice. No one can say that this player will 100% be a future HoFer, before said player even touches NHL ice.
And no, categorizing a player's importance by minutes on ice is not a solid argument.
