I was just thinking Macho Camacho fought (in his order of fights taking place): Edwin Rosario Ray Mancini Julio Cesar Chavez Felix Trinidad Roberto Duran x2 Sugar Ray Leonard Oscar De La Hoya and Jose Luis Ramirez who should also be in. Muhammad Ali fought: Archie Moore Sonny Liston x2 Floyd Patterson x2 Joe Frazier x3 Ken Norton x3 George Foreman Larry Holmes However, their resumes pale compared to Sugar Ray Robinson, who fought Henry Armstrong, Jake LaMotta, Carmen Basilio, Joey Giardiello, Gene Fullmer, Joey Maxim, Carl Olson, Kid Gavilan, Randy Turpin, Fritzie Zivic and Sammy Angott. Plus, Marty Servo who, like Ramirez, has been unfairly left out. Sal Sanchez had a very impressive 4-0, 4 kos record versus hall of famers, a record which (winning each of his fights versus hall of famers by knockout) is unequalled i think, but also it was only 3 hall of famers he faced. I'm talking about the amount of hall of famers faced, not the boxer's win-loss record against them.
