I remember watching Lawrence Phillips play football. He was great. Such a talent. Eventually Phillips served time in prison though. And he died in prison. He killed himself, and he likely did so due to mental health issues caused by injuries he sustained playing football. You can't take that kind of abuse and not have mental health issues.
Phillips went to prison on a 31-year sentence for domestic violence. Then he was accused of killing his cell mate and faced first degree murder charges.
