Joe is right of course, but I'm not sure if the Lakers have the skill set to bust a zone. Their inside players are too soft and their counterparts to big for the Lakers to be able to dump it inside. Their ball handlers can't penetrate and dish and the inside player can't find a way to get open. They also don't have the outside shooters to stay with Phoenix. Kobe is still unstoppable, but he's not getting anything easy for his team-mates. Artest is a liability because the Suns know he can't shoot a three, and playing a zone, means he can't put the ball on the floor. Fisher is too spotty a player to be of much help. The only one who can save them is Odom, but he'll need help to get going.
Kobe can't score and be the primary distributor, it makes defending the other Lakers too easy.
Phoenix isn't getting away with murder, they're playing team defense and it is killing the Laker offense. That is exactly what a good defense is supposed to do. Don't think for a second that Boston didn't notice the Lakers problems scoring against a zone. something Boston can easily do. BTW, Boston is built to bust a zone, that's what Ray Allen, Paul Pierce and Rondo are for.
Lakers misses translate into easy opportunities for the Suns bigs, who run the floor better.
Worst problem for the Lakers is that their 2nd team sucks, and Phoenix has a passable group.
Now, Phoenix has to be able to win one in LA. They have the formula, but do they have the will to impose themselves on the Lakers?
