Freddie Roach is a former boxer but more notably trainer for some of the most successful fighters in the last 20 years including Oscar De La Hoya, Mike Tyson, and more recently despite being Parkinson's stricken, Mannie Pacquaio. This is one of the reaons I love the guy: resisting his current star's recent obsession with religion he said: "I'm not religious. I try to be kind to everybody. If that's not good enough they can all go fuck themselves."
A young Mike Tyson with his famous trainer Cus D'Amato. He saw the lion and greatness in Tyson first. If he had lived longer he may have guided Tyson to even more greatness. Besides Tyson Cus D'Amato also trained Floyd Patterson
