I give all the credit in the world to SRL. In fact, he and Duran rank among the alltime ATG's in my personal opinion. Their first fight was one of the best ever. However, Duran did quit. He robbed us fans of witnessing a 2nd great installment in what was a riveting rivalry in boxing. Why did quit? I don't know, even after watching the HBO documentary about Leonard and Duran. Still..... I compartmentalize that into what was one of the most storied careers ever for a boxer.
