Here's a book on Sugar Ray Leonard:
The Big Fight: My Life In and Out of the Ring, by Sugar Ray Leonard and Michael Arkush.http://www.amazon.com/Big-Fight-Life-Out-Ring/dp/0452298040/
In his New York Times bestselling memoir, one of America’s greatest boxing legends faces his single greatest competitor: himself
In Washington, D.C., during the 1970s, a black man could get into the newspapers in one of two ways: crime—or boxing. “Sugar” Ray Leonard chose to fight. After winning a gold medal at the 1976 Olympics, Ray wanted to call it quits and go to college, but his family’s financial needs made him go pro. Boxing history was made. All the while, another, darker Ray—one overwhelmed by depression, rage, drug addiction, sexual abuse, and greed—battled for dominance. In The Big Fight, Ray comes to terms with both these men and shares a brutally honest and remarkably inspiring portrait of the rise, fall, and ultimate redemption of a true fighter—inside and outside the ring.
