I don't know if Ali would have killed anyone in his prime, but he would be a LONG night for ANYBODY whoever laced 'em up
A prime Louis possibly beats Ali, prime Holmes might do it, Foreman if he had the mental toughness, people laugh but Marciano gives Ali a long night in my opinion - he's a tougher version of Frazier in my opinion
Sugar Ray Robinson, Leonard, Duran, Hearns , Hagler ducked nobody during their day, true warriors as was Ali
