Why are you all so sure that the owners won't approve a move in a couple of years? Do you really think the other owners care so much about Sacramento that they'll block it? Of course not. Sacramento tried its best to build an arena. The city went way past what was expected, and what was even rightful, in their attempt to finance it. But even that wasn't enough. The city can't afford to put in more money, and the Maloofs refuse to.
Now it becomes a waiting game. How long do the Maloofs have until they become bankrupt? They apparently made a profit last year, so if they continue to keep this team in the dirt, paying minimum payroll, how long will it be until the BoG finally says "Fine, you guys can leave".
I don't see any hope in this at all. As far as I am concerned, the Kings are gone now. There is no chance of getting them to stay, unless some random investor came in to pitch the Maloofs' portion of the arena deal, which would never happen. Its game over.
