Describing the Sacramento Kings saga as too complicated to settle in a day, NBA Commissioner David Stern said Wednesday that the league needs "a lot more data and information" before it can decide whether the team moves to Seattle or stays put.

Following a long day of closed-door presentations in a Manhattan hotel, where contingents from Sacramento and Seattle separately pitched their cases for ownership of the Kings franchise, NBA officials offered no timeline for deciding the fate of the franchise.

Stern called both presentations "extraordinary," but said the league still has many questions that need to be answered.

Members of Sacramento's delegation, led by Mayor Kevin Johnson, were brimming with confidence after their two-hour presentation to a committee of influential NBA owners and executives. But Stern said the league wants more details on publicly subsidized arena plans in both cities and how each side plans to deal with obstacles, including potential legal challenges. The NBA is also looking for more information on how the competing bids to buy the team are structured.

As a result, the league's final decision on whether to allow the Maloof family to consummate its deal to sell the team to a Seattle group – and if not, whether a deal based in Sacramento is approved – may not come until after the league's annual board of governors meeting April 18-19 at the same hotel where Wednesday's pitches were made.

"We've never had a situation like this," said Stern, who appeared visibly fatigued by what he repeatedly called a complex situation.

The commissioner noted Sacramento's long history of supporting the NBA, including its latest plan for a downtown arena, but added there's "no question Seattle is a thriving, vibrant market."
