The Maloof family is asking NBA owners to approve the sale of the Kings to a Seattle group, saying there is "significant distance between us and the Sacramento group." In a letter sent to the NBA's relocation and finance committee, and obtained by The Associated Press on Friday, the Maloof family said the Sacramento group originally matched the $525 million valuation for the franchise negotiated by Chris Hansen, who is heading the Seattle group. Hansen then increased the valuation offer to $550 million last week.
