Microsoft CEO Steve Ballmer is leading a new effort to remodel KeyArena and bring another NBA team to Seattle as soon as 2010, reports the Seattle PI. “It should be noncontroversial, because it’s a city-only tax that already exists and will not be an increase,” said Deputy Mayor Tim Ceis. He said that the city would not spend the $300 million in renovations until a NBA team is committed to move here. The plan needs approval from the legislature.
