Outside of Cleveland and Golden State, I think the only other teams that stand a chance at making the Finals are Boston in the East and San Antonio, Houston, and OKC (if Westbrook goes out of his mind and weird things happen) in the West.
In fact, I wouldn't be too quick to advance Cleveland to the Finals, much less win a second championship. They have not been good since March 1 - 10-14 record. Their two saving graces this year is the East is incredibly weak (well, the NBA in general is incredibly weak outside of these 6 teams), and their one real good win since March 1 was at the Celtics.
That being said, I'll take GSW over CLE 4-1.
