LA's defense is not good at all so out scoring them is the way to go. Well, that's the way you win any game but you have to run up a lot of points on the Lakers because they will score on you.
I think the Lakers defence is highly superior to their offence. They are vulnerable to quickness/fastness and Fisher is a sieve, but they're still very good. Their offence, on the other hand, isn't working. Too much guys wanting to play the post, too little penetration and outside shooting, underwhelming ball and player movement, declining Kobe becoming more self-absorbed.
That said, I think Denver's chances of beating them are really small. They lack another quality big man + rebounding + another big time scorer/shot-creator.
