Answer
The memorable play Havlicek is known for is the "Havlicek Stole the Ball" play in the 1965 Eastern Conference Finals. With five seconds left in the game and the Celtics down by a point, John Havlicek stole the inbounds pass from Hal Greer of the Philadelphia 76ers, dribbled the length of the court, and scored a layup to secure the Celtics' victory.
