The Chinese Women’s Basketball Team player Chen Luyun was also a very good second center with good flexibility.  During the last match against New Zealand at the Athens Olympics, she threw herself in the air to save a ball from going out of bounds.  She caught the ball in her hand, but when she tried to land within the sideline, the anterior curciate ligament of her knee was torn.  After the examination, one of the main reasons given by the experts for her injury was her poor joint stability.
