This content is protected DAVEY MOORE June 16, 1983, Madison Square Garden, New York • Titles: WBA junior middleweight “Every since I was a kid, I always dreamed of going to New York. Madison Square Garden will always have a special place in my heart; it’s the mecca of boxing. I made great friends there, won championships there; New York belongs to me – a special place in my heart forever. I did surprise the world, didn’t I? (laughs) Everyone thought I was an old, washed-out fighter, that Moore for sure would put an end to my career. But I’m like a cat; I have nine lives. When I prepared myself to be my best, nobody could beat me. That night at the Garden, I was inspired and fully motivated. I was thankful to Davey for giving me the opportunity to fight him. I guess beating an old-timer would have been great to have on his resume, but when you are fighting with an old fox, you can’t be overconfident.” Result: Duran TKO 8 This content is protected IRAN BARKLEY February 24, 1989, Convention Center, Atlantic City • Titles: WBC middleweight “I asked (late president of the WBC) Mr. Jose Sulaiman, R.I.P., to speak to Barkley to give me the opportunity to fight him, and Mr. Sulaiman said that he would help me with the condition that if I lose the fight, I had to retire from boxing. So Barkley gave me the chance to fight him, because they told him I was already finished and it would be nice to add another legend to his resume. Also because he wanted to avenge Davey Moore’s defeat against me. They were close friends, and Barkley hated me for the way I beat Moore, R.I.P. When I saw Barkley, I saw how strong and big he was. I knew it was going to be a great challenge to beat him. But mentally and physically, even at 37, I felt very powerful during my training camp. I knew it was my last chance; I knew that everything was at stake. Mentally, I was so focused. I never saw myself getting defeated; it was never in my mind: What if I lose?’ Never! I went to Miami, Florida, to prepare myself in my training camp. I was sparring against 180-pounders. I was running with soldier boots on the beach, in the sand, to get my legs strong. I prepared myself physically so well that going the 12 rounds with Barkley was a piece of cake for me. Don’t get me wrong, he was a powerful puncher, strong as hell! But I was able to overcome him because of my experience of many years fighting. It wasn’t the first time I was against the ropes; I’ve been there before, and my mental toughness always came through for me. I had to use every trick in the book that night. It wasn’t easy, but at the end it was gratifying.” Result: Duran SD 12 https://www.ringtv.com/595279-hands-of-stone-roberto-durans-greatest-hits/ Roberto Duran: Best I've Faced BEST SKILLS Ken Buchanan: Buchanan was one of the great lightweights when it came to tactics and skill. His intelligence made him very difficult to beat even though he wasn’t a very strong opponent. Sugar Ray Leonard was faster and stronger but Buchanan had tremendous skills. BEST JAB Buchanan: He was tall, boxed well and his lateral movement was extremely good. Buchanan’s jab was difficult to deal with because he threw it on the move. BEST DEFENSE Buchanan: He was hard to hit cleanly. I was very young, lacked experience, and Buchanan had been world champion for a long time. A lot of people will expect me to say Wilfred Benitez or Leonard when it comes to defense but I wasn’t prepared properly for Benitez or the Leonard rematch. Davey Moore, who I beat easily, knocked Benitez out so there’s no comparison there. I was coming into my prime against Buchanan and he made me miss often. This content is protected BEST CHIN Marvelous Marvin Hagler: I hit Hagler with a lot of punches and he just kept coming. I didn’t find him as skillful as some of the opponents I faced but he was the toughest. BEST PUNCHER Esteban De Jesus: De Jesus was the first opponent to knock me down and he had me down again in the second fight. When I lost to Thomas Hearns I was drained from losing weight too quickly, and that had a bad effect on me. Hearns got me with a great punch but I could have performed far better in a rematch. Marvin Hagler, who is a good friend of mine, told Hearns the only reason he knocked me out is because I wasn’t at my best. FASTEST HANDS Sugar Ray Leonard: He was the fastest fighter I ever fought but in the first fight I saw everything that was coming at me. FASTEST FEET Buchanan: At lightweight the opponents were much swifter on their feet and, back then, we were boxing in 15-round fights. Buchanan always kept on the move but I caught up with him eventually. That victory means a lot to me. SMARTEST Leonard: It’s hard to give you one name but Leonard stands out because he made adjustments during fights. STRONGEST Hagler: It was an extremely close fight but he got me tired late. Even though I built myself up to middleweight, Hagler was much bigger and used his strength on the inside. After making weight, a fighter rehydrates and there was a big difference there. Still, even when I was tired, Hagler couldn’t get me down. There was no way I was going to get the decision but some fans and reporters thought I’d done enough. Hagler had big American fights pending with Leonard and Hearns so there was a lot of money at stake. BEST OVERALL Leonard: I have to say Sugar Ray Leonard because look at what he did in his career after he lost to me. It takes a lot to come back from defeat and Leonard did it.'' https://www.ringtv.com/462377-best-faced-roberto-duran/
He's top 5 and fair to leave it at that. For me no real way to say conclusively that any one fighter was the best but Duran is as good a shout as say SRR, Armstrong etc. Duran could be beaten. Aside from Hearns, which may or may not have been exacerbated by massive weight loss, he was decisioned by Kirkland Laing, who was a very talented British welterwight who sadly liked ladies, coke and partying too much. I only bring this up to remind that no fighter is unbeatable, even the greatest.
