I believe the 8/9/10 teams in the East would wipe the floor with the 8/9/10 teams in the West. That, to me, equals more depth and also takes into account teams like PHX (and MEM to an extent) being so much better than other teams.
Again, this is my opinion, and it is backed up by records, but that is how I would answer the question.
If you want to talk about full strength, then sure, Kawhi would probably help LAC and Murray/Porter would probably help DEN, but I thought we were just talking about this season. And it's not like the East has been totally injury free.
