It says that Phoenix made a smart move, and are positioned to win the Championship. On the offensive end Shaq did exactly what he needed to do. The Suns were effective in their half-court offense. Amare had more room to drive and fewer people to guard him. Nash had open lanes to pass into. Players were getting easy baskets off of passes out of the middle.
The Suns need to work on their defense- something that will take time, and probably a lot of work by D'Antoni, as the Suns never were committed to defense and will not win the title without it.
Shaq makes them a better team in the post, but it's going to take some time for the Suns to learn how to use him to best advantage.
I'd expect whining Lakers fans to criticize anything that Shaq does, but it's all sour grapes. Shaq is clearly the key to the Suns future. And will be the difference maker for them in the playoffs. He was hurt in Miami, and had time to convalece, but all Laker fans say is that he was dogging it in Miami, even though he was out for several weeks.
The West doesn't belong to any team right now. The Spurs are just another team competing for a title, along with the Lakers, Mavericks, Spurs and Suns. New Orleans is just as good as any of them, and Denver and Utah are both very good. Only Denver has managed to beat Boston.
