Sugar ray Leonard chin?

Duran mauled him pretty thoroughly in their first fight, and he took most of those shots fairly easily.

 

If your counting Ecklund as knock down, we must count Hagler's "knock down" against Roldan. All of Leonard's knock downs came after his 1st retirement, and against inferior competition than what he faced prior too that 1st retirement. All the multiple retirements the cocaine , alcohol, and partying took a lot out of Leonard. But at his best he walked thru possibly , probably the most dangerous puncher in welterweight history without much of a problem.... And Hearns landed plenty of straight right hands cleanly early in the fight... In fact, that ability to take Hearns power gave Leonard the confidence too get of his toes( Because he was certainly losing the fight on the outside) And brawl with Hearns that ultimately lead to his winning that fight. Also Duran landed many clean shots on Leonard in Montreal , and so did Kalule who was the bigger man without much effect.

He had a great chin during his prime. It is when he came back. The fact that Camacho was able to floor him should tell the story.
