Not really. This is the list of unprotected players:
NHL expansion draft unprotected lists released
Not all that many top 6/4 guys as people remember. Some good players like MA Fleury, James Neal, Jonathan Marchessault, Sami Vatanen, Reilly Smith, Josh Manson, Ryan Strome, Dustin Brown, Marc Methot and Toby Enstrom and Troy Brouwer.
There were also "names" available (Jagr, Iginla, Gaborik, Michalek, Lupul) too, but at the end of their careers.
Vegas took a few of those guys and it was certainly a decent foundation, but not exactly the haul people are making it out to be. People are looking at what the players became vs. what they were at the time of the expansion draft.
Vegas definitely had a way, way, way better setup than Ottawa, Tampa, Atlanta, Minnesota and Columbus, but they weren't gifted anything. They just took the right mix of players, and have been incredibly aggressive since.
Everyone still thought, looking at their roster, that they'd be one of the worst teams in the league.
