Sacramento business leaders are asking NBA Commissioner David Stern to "strongly encourage" the Maloof family to sell the Kings so a deal for a new arena can move forward.

In a letter signed by about two dozen of Sacramento's most powerful businesses leaders and sent to Stern on Thursday, the group accuses Kings owners Joe, Gavin and George Maloof of not negotiating in good faith. It also questions whether the Maloofs have the finances and motivation to keep the team in Sacramento.

Family spokesman Eric Rose said the Maloofs are "saddened and disappointed" by the letter. He says the Maloofs are not selling the team and are committed to help fund the estimated $391 million arena, which would open for the 2015-16 season.
