I agree that we need to produce a balanced offensive attack so that everyone has to play defense, including Luka. We don't want to let him just stand in the corner. But I think we also need to be careful not take ourselves out of our regular offense because we are trying to match up hunt to make Luka work. If we work our offense, work our sets, that should be enough to force everyone to play defense.
On any given possession, we may be better off attacking Kyrie for example, or getting a 3 for Porzingis or Horford (making Gafford/Lively come out). There may be times that we want to attack Luka, maybe have Brown take him down low, but don't let that get you out of what you need to do.
We should be the better, more balanced team. We should do what we do and force them to adjust. It tends to backfire if you start changing.
