The Milwaukee Bucks NBA team is threatening to move to Las Vegas if they don't get a new arena. According to multiple reports the Bucks are seeking up to $250 million of public funding which would pay for half the cost of a new arena in Milwaukee.
Most people think this is just a scare tactic and the Bucks will remain in Wisconsin. However Las Vegas is becoming a very attractive option for hockey and basketball teams because of the brand new MGM arena that is currently being built on the Strip.
Every team wants to play in a nice arena, and Las Vegas will have one of the nicest. I think getting an NHL hockey team is more likely for Las Vegas than getting an NBA basketball team, but I would't be surprised if either happened in the very near future.
