Boston Celtics again?

Do you think that the Celtics will win the championship again. In my opinion no. There are so many good teams this year in the East. Philadelphia will be a powerhouse. Wizards got Arenas back. Miami has a healthy Wade and Michael Beasley. Plus in the West theres gonna be teams like Portland and Clippers that could turn out to be shockers. The Hornets will do much better. Lakers will get Bynum back. The Suns might shine just like before. And also The Mavericks looked very stacked. So overall I think Boston will lose in the second round. What do you think, will the Celtics win? How far will they go if no? Why???
