There's no Las. It is just the VGK. The owner, Bill Foley, is from West Point. West Point's mascot is the (Army) Black Knight. There is already a hockey team called the Knights (London, Ont.). This is the result of a great deal of compromise and corporate sanding.
They're really missing out not having any teams in Portland or Seattle (I know they're waiting for Seattle to get that stadium built so that Seattle can be our "local team" like The Seacucks and Mariners).
Yuck. Logo looks like a golden tit, which is actually somewhat appropriate given the location. They may as well drop the whole "golden" part now though, because nobody is going to be using it. The Mighty Ducks just turned into the Ducks, etc. Nobody wants adjectives in a team name, slap a noun down and quit being pretentious. I will be calling them THE TITS.
I've heard of people having "golden nights" in Vegas. But then, what happens in Vegas, stays in Vegas.
Honestly? This logo looks like some sort of generic moniker option for video games or something... This is pretty weak.
