Scouts that spend decades watching prospects also miss good players and draft lousy ones. We don't take their opinions as gospel
You might know more about goaltending than the other guy but I don't think every opinion that disagrees with yours should be thrown out the window because you've spent more time doing this.
No offense, but if someone admits he's never played the game, doesn't know much about goaltending, and didn't really watch much of the guy play, but swears that the goalie in question is a huge bust, then it's hard to take his opinion too seriously.
