There doesnt appear to be many if any advanced statistics for goalies. .920 save percentage is an arbitrary number. Tristan Jarry is in a different league with a .938 sv%. So if save percentage is worthless, then someone with a .500 save percentage may be actually better. Of course Im being facetious b/c they wouldnt be in goal. It does in fact mean something. Agreed by itself, no but there are few metrics for goalies. To Fucales credit, he is statistically second in the Q in GAA where the Q is having an extremely strong year for scoring so goalies are taking at hit across the board. Difficult to compare different leagues.
As far as viewing goes, Im sure the experts had ample viewing of previous first round goalie picks. Lets start from 2006. Six years is adequate time for a goalie prospect to develop. From 2006 going backwards to say 1999, the attrit of first round goalie picks is staggering. Of course everyone knows picking a goalie in the first round is probably the most dicey decision a team can make. Did the scouts not have adequate viewing or perhaps scouting was lacking.
Fucale did nothing to enhance his position by the HH Top Prospects game. Doesnt mean he wont go in the first round or be successful. I hope he does. Canada needs to produce goalies. By the same token, Id much rather roll the dice with Jarry in later rounds.
If you want to have the statistical conversation regarding Jarry, go ahead. The way to do it is to take each goaltender and figure out their comparative value in their respective leagues (so figuring out what the average is for goaltending in the league and then how far above average each one is).
And then you'll need to single out the effect of the goaltender separate from overall team defense. So that's identifying how strong a team is defensively in comparison to the average of the league and then separately judging how the team plays in front of one goalie compared to another.
Also in Jarry's case where he filling a backup (or perhaps a tandem role), you'll need to consider the quality of the opposing teams he faces. I don't know anything about him or how Edmonton decides what games he plays in, but in the 16 games that Edmonton has played against the other top 5 teams in the WHL (Calgary, Prince Albert, Kelowna, Kamloops, Victoria), Jarry has played in 4 (so 25% of them). In the 13 games that Edmonton has played against the bottom 5 teams in the WHL (Moose Jaw, Regina, Brandon, Vancouver, Prince George), Jarry has played in 8 of them (so 61%). How do we put his statistics in proper context if he normally plays the league's weakest teams?
Finally, your point about busts and scouting is irrelevant. What we're discussing is the best way to assess players. That continues to be conventional scouting and viewing. That doesn't mean it is foolproof (and I don't think anyone has claimed that it is), but despite the imperfections, it is still the best way. Of course, if you'd like to dispute this by doing some math about past drafts to show that drafting based on statlines alone would yield better results, I think that would be an interesting read.
And when you say that his play in the Top Prospects Game did nothing to help him, in who's eyes are you referring to? Is it simply because he was the only goaltender on the ice to give up goals?
