The real difference is that Anaheim has already started collecting young talent and is much further along in their rebuild than the Sharks are
Since the Ducks started tanking they've already added Zegras, McTavish and Carlsson to this year's roster
They also added Kilorn and Gudad this year in UFA
Since we started tanking our 1st round picks of Smith and Musty are still in college and major junior and we added Duclair, Hoffman, Granlund and Ruuta through trade, those guys don't have the same winning pedigree as the Ducks free agents unless you want to compare Gudas to Ruuta, and even then it's questionable what impact he would have on a bottom feeder with no support
The Ducks are starting their upswing based on the development of their young players (and also some pretty lucky comeback wins, if we're being honest)
The Sharks aren't yet at that point in the rebuild, we're arguably still in the teardown phase, we haven't added a single young player of consequence outside of William Eklund, and he's not the kind of prospect that will alter our fortunes all by himself
The Sharks are probably going to look about this bad for the next 3 years at minimum unless we luck into a transformative talent in the draft lottery, this is gonna be a real slow burn
