If I was an NBA player like Chris Paul for example, who get injured often, I would retire. What else does he have to prove? If its ring chasing, it's not worth it, because its probably not going to happen. Why not just go home and relax. Maybe it's the contacts? Maybe its their addicted to fame? Maybe they really really love the game? Whatever the reason is I wouldn't be putting my body through that torture if I was a multimillionaire. Have you seen what Shaq did to his feet playing basketball? How can he even walk?
