Former Dallas Cowboys offensive lineman Nate Newton says he went into the drug business because of his competative nature. "I've always been competitive, I've always been in sports," said Newton, a six-time Pro Bowl offensive lineman who retired after the 2000 season. "I couldn't see myself not being the biggest dope man." Newton, 43, was released from a Louisiana prison last year on drug possession charges after serving about 2? years behind bars. Newton estimates that he stood to make up to $75,000 per drug deal, another reason he said running drugs appealed to him. Newton made his comments Thursday during a talk show on Dallas radio station KKDA. He said he became remorseful while serving time in a federal prison in Texarkana, before he was transferred to a federal facility in Louisiana. "I got on my knees and said, 'God, I want to make a deal. ... You protect me in here, and when I come out, I'll do everything I can to make it right,'" he said.
