Houston Rockets rookie center Alperen Sengun has begun to learn the tricks of his position by one of the best-ever big men: Hakeem Olajuwon. The Rockets released a video on Twitter that shows Olajuwon showing spin moves (including his signature Dream Shake), teaching lessons and providing advice to Sengun on when to move the ball to the basket or take the shot that the defense gives him. “To be a complete player, you feel free on the court,” Olajuwon tells Sengun. “The most important is the foundation of all the moves.”
