Hypothetically Speaking, if the Mavericks?

If the Whole Mavericks team died in a plane crash or true some other tragic occurence, what would happen for the WCF. Would the winner of the Memphis-OKC playoff automatically go to the Finals? Would that matchup basically be the WCF? Or would the league do something else? I'm not saying this to offend anyone just to clear that up, I'm just asking. that's all.
