When Victor Roundtree started hanging with drug runners in Brownsville Brooklyn as a young man, his old boxing coach pulled him off the streets and taught him how to train boxers. But Roundtree struggled to leave his old life for good. Today, Roundtree, fully reformed, coaches kids at the Teddy Atlas Cops and Kids after-school program, which will soon open its third gym in his native Brownsville. In an interview, Roundtree discusses what eventually got him off the streets for good.
