Stern has explained that there is a huge difference between what's happening in Seattle and the situation in Sacramento. No government entity in the Seattle area has indicated they want to get an arena deal done. Heck, Seattle even passed a law prohibiting any public financial support for anymore sports stadia or arenas.
The baseball and football stadia were built with public money deals. And public funding built earlier stadia and arenas. Sacramento has never done a stadium or arena deal.
Stern says all the various parties he's talked to in Sacramento want to see an arena deal of some kind get done. That's one of the reasons he was willing to get involved in trying to get a deal done here and didn't in Seattle. NBA overtures were completely rejected in Seattle. That and the fact that the Maloofs asked for Stern's help and the owners of the Sonics never did.
Even though the circumstances are very different, if the NBA doesn't come up with an arena plan that will work, the Kings will be gone.
There is really no comparison between the situations.
