Boston Celtics vs Philadelphia 76ers

The rivalry between the Boston Celtics and the Philadelphia 76ers got started when the Syracuse Nationals left upstate New York in 1964 and moved to Philadelphia and became the 76ers. The rivalry began with a bang in the 1965 playoffs when the two teams met in the Eastern Conference Finals. The two teams battled for seven games, and the Celtics had a 110-109 lead in the seventh game but turned the ball over in the final seconds. However, when the Sixers tried to inbound the ball for a winning shot, John Havlicek deflected the ball to teammate Sam Jones, and the Celtics held on for the victory. They would go on win the NBA title. That series would always be remembered as the one where Havlicek stole the ball.
