When it comes to ranking the four boxing legends known as the 'Four Kings'—Sugar Ray Leonard, Marvin Hagler, Thomas Hearns, and Buddy Duran—certainly, it's a matter of individual preference and subjective opinion. Each fighter boasts a unique and distinct style that contributes to their legendary status. Here, we outline a ranking based on both boxing ability and style, while discussing the strengths and weaknesses of each fighter.

Ranking the Four Kings

1. Thomas Hearns

In my eyes, Thomas Hearns emerges as the most terrifying of the Four Kings. Although he faced questions about his chin, his lightning-fast fists, incredible body mechanics, and the sheer ferocity with which he wielded his punches make him an absolute nightmare for any opponent. If I were to choose one of these fighters to avoid, it would be Hearns. He is the embodiment of a boxer who can defeat you in every conceivable way, whether it's through combinations, brutal power, or sheer speed.

2. Sugar Ray Leonard

Leonard is undoubtedly a powerhouse among the Four Kings. He was a master tactician, with a perfect understanding of the ring and a remarkable ability to adapt to any situation. Leonard's speed, technique, and confidence were unmatched. Even warriors like Marvin Hagler and Buddy Duran found him challenging, as evident from Leonard's comeback fight in the early 80s when Hagler lost his detachment retina. Despite boxing for about 40 fights, Leonard's longevity and success in the ring make him the second on the list. His poise and skill were what truly set him apart.

3. Marvin Hagler

Marvin Hagler was a relentless, no-nonsense fighter who fused strength, endurance, and a relentless attacking style to perfection. He embodied the traditional boxer's virtue ofnever quitting. Hagler was always moving in and forward, and he brought the best out of his opponents. He even managed to knock out Hearns, which speaks to his immense skill and drive. Hagler may not have the sheer rapidity of Hearns or Leonard, but his methodical approach and ability to wear down his opponents make him a formidable force. His ranking as the third is a testament to these qualities.

4. Buddy Duran

Among the Four Kings, Buddy Duran is often considered the most overrated. He did have that 'Mexico tough guy' charisma and powerful punches, but his skills as a boxer are often questioned. Duran's career was marked by a 'no mas' incident, which is undoubtedly a blemish on his legacy. While his methods and approach to boxing are respected, the fact that he faced a management that pushed him into risky fights reduces his overall ranking. Nonetheless, his ability to fight tenaciously and drop powerful punches gives him a place on this list, but he is more of a 'scraper' than a masterful boxer in my estimation.

Conclusion and Discussion

Each of these fighters is an icon in their own right, and their legacies are woven into the fabric of boxing history. Leonard's poise, Hagler's endurance, Hearns' speed, and Duran’s toughness make them all unique and indispensable to the sport. This ranking is subject to personal preference, and there are valid arguments for different rankings. Ultimately, the decision comes down to one's own prioritization of speed, technique, endurance, and overall strategy. These four fighters together form an unparalleled quartet in boxing history, each leaving an impact that resonates to this day.
