Roberto Durán

Durán was violence personified. His nickname — "Hands of Stone" — wasn't marketing. It was a medical description. At lightweight, he carried genuine one-punch knockout power in both hands, which is rare below 140 pounds. His style was old-school pressure: walk forward behind a high guard, cut the ring, get inside, and work the body until the opponent broke. The body attack was systematic. He'd dig to the ribs early, soften the midsection, then switch upstairs when the elbows dropped. Inside fighting was where he lived — he'd smother his opponent's offense in the clinch, dirty them up with forearms and shoulders, then rip short hooks when the referee broke them. Against Sugar Ray Leonard in their first fight (1980), Durán did the impossible: he made Leonard fight his fight. He bullied a faster, more skilled boxer into a brawl and won by sheer force of will.
