This may actually be a disadvantage for the LA teams. Every other team has a clear advantage at home, not only because of the away teams traveling, but the referees being influenced by the home crowd. Neither the Clippers or Lakers will have that home court advantage by not traveling. Who do the referees side with, if the crowd is 50/50? Will we finally see a series, where the actual teams decide who the better team is? Far too many times, series are decided by a home court advantage.
BTW, if anything, an all LA series, may hurt the Clippers, as there is no way the crowd is 50/50. If anything, the crowd will be 70/30 or 60/40 Lakers over Clippers fans. And that is where the referees will be influenced.
