7. Golden State Warriors (23-13, previous ranking: seventh): The Warriors' challenging January continues with games against Miami and at San Antonio. Even the improving Hornets can't be dismissed.
8. Indiana Pacers (23-15, previous ranking: ninth): The Pacers have two All-Star candidates in forward David West and swingman Paul George. Does Indiana deserve two All-Stars?
