True, a lot of teams that doesn't have close ties to any of the so cal teams won't really care other than not wanting to pee off the other teams' owners. I don't think people care much for what Sterling thinks. Honestly, even Buss, phil jackson etc all have vocally stated how much they despise Sterling.
As for Buss, do most owners rather watch the lakers get stronger with their new TV deal and successfully defend their territory, or would they rather weaken the lakers/clippers by approving anther team nearby? Most teams are always gunning for the lakers.
I just can't see teams like the Spurs, Mavs, Celtics, Heats, Thunder, Magic etc want to help the lakers defend their territory and retain their market share. If anything, this is a great opportunity to throw some trouble to the way of the lakers without having to do much themselves. There are those other teams such as the Rockets, Pacers that have been long term trade partners of the Kings. The kings have also been "helping" teams left and right by taking junk players in order for those teams to get under the cap. Yes they get money in return, but its still a favor.
My question would be, has there been any team in history that filed for relocation and loss the voting? I looked it up a bit and found one where the Wolves tried to move and filed but that had to do with another company coming in trying to buy the team and then move it.
