Greatness Over Decades

Only the New York Yankees and Boston Celtics have sustained greatness across the decades. Like them or not, no one can deny that these teams have contended for and won championships, not simply for consecutive years, but spanning different eras of play. It was not simply the Ruth or Russel Dynasty in the respective sport but multiple titles with different personnel over the course of more than a century for baseball's dominant team and over a half century for basketball's Celtics. And it continues into this very year with both teams still vying for titles.
