Personally I really don't care what they call the team. With that said tho... if it was me and I was starting a team in the nhl... and I was in a 2 worded city... Las Vegas Los Angeles San Francisco etc...
The last name of my team would not be 2 worded. It's just a little 2 wordy for my liking. Knights works. Las Vegas Knights. Sounds good. Why go with the 2 worded last name when you are a 2 worded city. Just sounds so stupid
