I can't even call the west right now... Whoever wins it will take it. I originally called the Pistons. I'll go with the Celitcs.
If Lebron single-handedly beat the eastern conference last season, then Boston can do it now. Their lack of depth, however, will hurt them. They will not have an easy time by the time they get to the eastern conference finals. The winner of the west may be battered as well, but IMO will proven to have far superior depth over the Celtics and more ability to handle a best of seven.
