Slash has a good point. Nunn sparked Kalambay in 1 round though would take McCallum to split decision shortly after. Carlos I think is a level up being top in the top 3 of all time for most observers with defeats early in his career all avenged. Shot accuracy power aggression I see Carlos finishing Sumbu in under 10 rounds.
He was KO'd once in his career and looked fine right up until that moment. I don't think you can base the outcome of this fight on a single incident when there is so much evidence against that happening. There really needed to be a rematch.
If King Carlos Monzon has beaten the likes of Nino Benvenuti, Emile Griffith, Jose Mantequilla Napoles, Bad Bennie Briscoe, and Rodrigo Valdes, not once but twice, he could have beaten Sumbu Kalambay. Carlos was 5"11, had a long reach, iron chin, good counters to the head and body, plus a crunching right hand that produced 61 KO's in his 89 victories with just 3 losses, the last one being on Oct 9 1964, he won his last 82 bouts in a row, revenged his three decision losses. He retired as champion, 14 title defenses. Kalambay may have speed of hand but Carlos knew how to dictate a fight on his own terms, he was calm, cool, and collected during a fight, showing no emotion. Carlos by KO 8. Carlos fought and beat the opponents from his era, not the past or present fighters.
Monzon, Sumbu when he fought the best of his era lost, Monzon dominated his era. Monzon would figure him out, systematically break him down and win by either ko or wide points decision.
Kalambay UD. Nunn's performance is irrelevant to Monzon's chances. The former is a southpaw and Sumbu had trouble with them.
Monzon struggles early on with the slick movement before slowly adapting and giving a workmanlike performance to the body, before eventually setting up, and landing, his right hand. Think the Napoles fight but inverse - constant backwards slickness instead of forward. I see Monzon landing his straight right to the body, under the jab, more and more until he can eventually land his right up top and his left hook. And of course this would all be predicated off his jab, which he would lead with regardless of landing or not. Finally the right uppercut would probably come in to play as Kalambay's feet shut down somewhat late. Monzon decision imo. I'd like to hear some actual arguments for Kalambay though - he was a hell of a fighter.
Kalambay could make this interesting for a while. He was slick but a little open, when on the offensive. I think Monzon could draw him on and start to find the openings after a few rounds - taking advantage of these on the counter. By midway, Monzon is hurting Kalambay regularly and a stoppage is looking imminent by the close of round-9. Kalambay may hang on and survive the championship rounds to award Monzon a comfortable UD.
