Kobe creates great looks for his teammates this year
I don't think Kobe has really changed his play that much, he just has a better supporting cast now.
Bynum has developed into a fine and productive young center on both offense and defense.
Fisher was a good add to the team
Farmar has developed into a quality bench player on both ends of the court.
Ariza added another good athlete and defender
This Lakers team really defends hard and well, it's easily the biggest reason for their great start. Last year they were a mediocre defensive team, this year they are a top 5 defensive team allowing only 43% shooting. I don't think it's a fluke either, the Lakers have plenty of good athletes that play defense along with a top notch head coach.
