Boston hasn't been playing that well offensively yet this season, and yet they're still 19-2. That's crazy. None of their main three stars have had great seasons up so far. Offense can come and go from game to game, but what separates the Celtics from the Lakers is Boston consistently competing at the defensive end every single game. Their defense is really the hallmark of how great a team they are. That's why they are a better team than the Lakers right now and probably will be at the end of the season.
