Boston Celtics star Paul Pierce proved that he can still throw down incredible dunks at 33 years old. In the fourth quarter of Boston's 93-79 victory over the Toronto Raptors on Sunday, point guard Rajon Rondo handed the ball to Pierce who had a wide open lane to the basket. Pierce drove and had two Raptors waiting for him under the hoop. The 12-year veteran cocked back the ball in his right hand and slammed it in over Toronto's Amir Johnson to extend their lead to 82-75. Scroll down to watch the dunk.
