 In the NBA, his 20 seasons and 1,560 games are performances surpassed only by former Celtics center Robert Parish.Abdul-Jabbar was well known for his trademark "skyhook", a hook shot in which he bent his entire body (rather than just the arm) like a straw in one fluid motion to raise the ball and then release it at the highest point of his arm's arching motion.Combined with his long arms and great height, the skyhook was difficult for a defender to block without committing a goaltending violation.
