Date: 1959-66
Set By: Boston Celtics

When LeBron James bragged about winning all those championships in Miami, we're guessing this is the dynasty he was thinking of. Unfortunately for James, the Celtics' eight titles in a row is inconceivable in today's game. Remember how big a deal we made of the Bulls' and Lakers' three-peats? The Celtics had almost three of those in a row. They had a multitude of Hall of Famers, not just two or three "superstars." They amassed more talent than any other team could possibly match, something that is simply impossible in the current NBA. Unless the salary cap goes away, this record isn't.
