It wont be the same, because how much of a fan base is it gunna have? cause look at it this way, most people who live in vegas werent born there, so they have different home teams they like, so even if the odd person decides they like The Vegas team, then they would go bankrupt, cause their games wouldnt sell out.
But you can also look at it this way, for all the people who moved to Vegas and like other teams, they will want to go see their team when Vegas is Playing at home, so then they will end up selling some tickets to people who dont even like them, their just there to see them lose.
Its Defenently a great Argumentable debate, but Vegas would obviously go into the western conference and then they will have to redo the divisions, and then they will need to expand for another eastern conference team to make things even, and throwing around the divisions could be good for the league.
Add: Oh, and when you get those crosby cards, if they do get signed, can you try and get a picture of him signing them? kind of like a picture of authenticity, if you know what i mean lol.
