Here in the gilded conference rooms of the St. Regis Hotel, two blocks from NBA headquarters, Sacramento and Seattle leaders have their day in court today. Each will try to persuade a pair of NBA owner committees that their city most deserves to win an unprecedented battle for the Sacramento Kings. Both cities are sending heavy-hitter groups to those meetings, which are expected to last the full day. The committees will issue a recommendation to the full NBA Board of Governors when it meets here in two weeks for a vote. Chris Hansen, an investment fund manager, is expected to be first up today, sometime after 9:30 a.m. EDT. Hansen leads a group that has signed a tentative deal with the Maloof family, current team majority owners, to buy the team. He is expected to be accompanied by George Maloof, as well as Seattle's Mayor Mike McGinn and county Executive Dow Constantine. Steve Balmer, CEO of Microsoft, is partnering with Hansen, as is the Nordstrom family. "We're just going to go in and tell them the story," McGinn said. "Our emphasis is trying to make them understand what we are trying to do in Seattle."
