Thomas Hearns Ranks Roberto Duran Above Leonard and Hagler
The Hitman beat Duran in two rounds but lost to Leonard and Hagler — yet it's the Panamanian he puts highest among the Four Kings.

Thomas Hearns has done the thing every old rival dreads: he's made a list. And on his all-time ranking of the Four Kings, the man he places highest isn't Sugar Ray Leonard or Marvin Hagler — it's Roberto Duran, the only one of the three Hearns actually beat. He needed just two rounds to wreck 'Hands of Stone' at Caesars Palace in 1984, yet Duran still sits above the two men who own wins over 'The Hitman'.
Speaking to Boxing247, Hearns put Duran ahead of both Leonard and Hagler, an eyebrow-raiser given how the head-to-heads actually shook out. Leonard handed Hearns his first pro loss with a 14th-round TKO in their 1981 welterweight unification. Hagler stopped him after three of the most violent rounds ever fought in 1985. The scoreboard says one thing; Hearns's ranking says another.
The Caesars Palace Ledger
Every one of Hearns's Four Kings fights ran through the same Las Vegas venue, which makes the pattern easy to trace. Leonard in '81 — loss. Duran in '84 — a two-round demolition. Hagler in '85 — a three-round loss in a war people still argue about. Then a Leonard rematch that came back a draw, a result Hearns, the crowd, and reportedly Leonard himself thought should have gone the other way.
So Hearns's personal 2-2 record against the Kings, with two of those results heavily disputed, doesn't neatly map onto how he rates them. That's the interesting part. He's not ranking by who beat whom. He's ranking by what he saw and felt across the ropes — and Duran, the man he blitzed, apparently left the deepest impression.
Where Hearns Puts Himself
Hearns didn't stop at his contemporaries. On his broader all-time list, he slotted himself third, behind only Joe Frazier and Muhammad Ali — the heavyweight pair whose three-fight rivalry remains the benchmark for boxing trilogies. It's a bold placement, but the man earned the right to be bold: four fights against the era's best, and nobody ever caught him backing down.
Rankings like these tell you more about the person making them than the sport they're measuring. Hearns fought all three of his fellow Kings, beat the toughest reputation of the bunch, and still tips his hat to Duran above the rest. Coming from a fighter who traded on brutal, ruthless finishes, that's about as high a compliment as you'll get.
