I think this is a good move for the A's organization.
(1) Las Vegas has a larger population than Oakland.
(2) More out of town people come to Las Vegas than Oakland, and that should help with attendance especially if it is a really nice park with a lot of extras. Can they set up a gambling casino in the park with a big screen TV and have people bet on the game as it is going on?
(3) It sounds like they plan to keep the name Athletics. I'm not sure if that is a great idea. The Las Vegas Raiders sounds good, but the Las Vegas Athletics? Yuck. How about the Las Vegas Gamblers? I like that and the residential population will like it too. Or how about the Las Vegas Aces? That's even better. If they call themselves the Las Vegas Aces, they can keep the same hat and logo with the A. Aces refers to card games, but can also refer to ballplayers or a pitching staff more specifically. The name "Athletics" has been in MLB since the early 1900s, I get that, but there are better options for Las Vegas.
