Perhaps, but another way to interpret this is it is precisely Stern and the BOG behind it.
In other words, the BOG doesn't want to tell a sitting owner who they can and can't sell to, not officially. But in this case they are telling the Maloofs they damn well might. So what does the NBA do? They talk to Seattle about the expansion option, ask them if they back out of their deal with the Maloofs will they accept expansion as an alternative? Then the NBA goes to the Maloof and tells them, not asks, TELLS them, contact Sacto if you want your money. If Sacto matches Hansen, then bring it to the BOG, and we'll approve it and you'll have your pound of flesh, and good riddance. If it happens, Hansen abruptly pulls out of the offer, the Maloofs then switch over and accept Sacto's offer. And then all the BOG has to do is accept the sale without ever officially voting against the Maloofs sale to Hansen. Hence, no precedent they don't like, but they still get the right result.
