I think, with certain exceptions, Habsfans are patient. More specifically, they're willing to be patient if a rebuild is done correctly.
Who isn't patient, however, are many of the old dinosaurs in the media. There were plenty of them that said before last year's draft, alright cool, now we can start trying to make the playoffs!
CH1 is also right: You can't keep getting top-5 picks and coming out with disappointing players. End result has to be, we need to get an elite talent in some of them or at the very least, players that might not be worth the selection spot, but carve out good and long careers with us. You can't have more Galchenyuk/Kotkaniemi picks where they're playing hockey in their mid-20s elsewhere.
Right now, we only have one elite talent in the whole organization: Cole Caufield. There needs to be at least 1-2 more years of tanking, get one of Celibrini/Eiserman and one of Misa/Hagens in 2025, now we're talking.
