I can usually tell how good a book is by how long it takes for me to get through it. I was done with this in no time.
The Big Fight by Sugar Ray Leonard is an excellent autobiography. I already knew some of the background to his biggest fights from having read Four Kings by George Kimball and the Roberto Duran biography, 'Hands of Stone'. But there was still so much insight leading up to and during Leonard's greatest and worst moments in the ring that the book still reads very fresh as we are taken through his outside distractions during the build up to those fights, his psychological state when approaching those challenges and his opinion on his opponent.
The first two Duran fights and the Hearns and Hagler battles are obviously gone through in fair detail as you would expect, as well the Olympics and winning the title vs Benitez. But the 'lesser' fights he took in between these were interesting in how he approached and tried to balance his outside activities and stay motivated for them, which he found very difficult.
Sugar Ray is extremely honest in his exploits both inside and outside the ring. He had it all; the talent, the money and titles but that in itself is what brought the temptations. The endless women, alcohol and drugs. Having battled many demons over the years he readily admits he wasn't the best person to be around and that it impacted his relationship with his wife and first two children. There were things that happened to him during his childhood which he tried to shut out over years through the booze and drugs until he couldn't anymore.
