Milwaukee Bucks Looking to Build a New Arena
However the reason is simple — it’s one of the worst buildings in the league. And cities with worse ones — for example, the Sleep Train in Sacramento — are already moving well along on plans to replace their structures.
The Bucks signed a lease extension in 2011 that runs through 2017, but by the end of that a plan to get a new arena built is supposed to be in place (or maybe even work could have started).
