He's got a good point.
Here in Milwaukee the chances of a new arena getting approved/built is somehwat of a long shot...Their current home (Bradley Center) was funded by the Lloyd, and Jane Petit, and was completed in 1988 for an NHL expansion franchise.
Well - the Petit's didn't spend the extra $$$ for the franchise fees, and so now the NBA Bucks are looked upon as the main tenant, and the new owners of the Bucks feel the building is antiquated.
Personally - I feel the Bradley Center is just fine, and if the Bucks leave.....Oh well.
Off topic, but this is incredibly uninformed. First of all, the deal passed the state senate and was never a long shot to get done. Second, the NBA, not the owners, set a deadline of 2017 for the Bucks to have an arena in place before the owners even bought the team. If a deal wasn't done, the NBA would forcibly buy the team back from the new owners.
