First, an explanation.
I'm ranking NBA teams based on how they will perform in the regular season, not in the playoffs. There is certainly a difference, as those who watched Bulls-Heat in 2011 or Cavs-Celtics in 2010 can attest. Certain depth-laden teams will win more regular season games than top-heavy squads that are better suited for the playoffs.
Just know that the regular season is different from the postseason. Also know that, between a massive James Harden trade and huge Los Angeles talent haul, we should be in for a fantastic 82 games.
