not really... unless there is something somewhere that dictates the NBA assumes ownership they can't force anything. (my understanding from what i've read)
the only thing "forcing" the maloofs to sell is their perilous finances, that said they could turn around once it's rejected and sell to a group from KC.
As Brick mentioned above, the Kings are a franchise, and the NBA, like any other franchiser is able to dictate who can and can't buy a franchise. I believe somebody elsewhere came up with the scenario as follows: Imagine a known foreign druglord billionaire executed a purchase agreement to buy an NBA franchise. Do you honestly think the NBA has no protection and no ability to block the sale to such an undesirable owner? Of course they do.
It may well be true that they can't force the Maloofs to sell, though I'd expect that one could rather say that they have not seen fit to execute their power to force the Maloofs to sell. (Again, imagine that the Maloofs were accused and convicted of being druglords. Do you think the NBA at that point couldn't seize the franchise?) The NBA almost certainly has the power to unilaterally seize the franchise, but use of such power must be
extremely judicious. Maloofery just doesn't cut it. So will the NBA use whatever power they have in them to force them to sell, assuming they reject the Hansen deal? No. But the NBA won't have to, as the Maloof financials are clearly bad enough that they have to sell, and they will quickly turn to a buyer that the NBA
will approve (read: a local buyer) in no time.
