Roberto Durán spent his entire career staring down the most dangerous men on earth, and he never looked afraid. But late in life, when asked which fighters truly left a mark on him, he named five, each representing a different dimension of greatness.

Thomas Hearns for power. Carlos Monzón for danger. Marvin Hagler for heart. Sugar Ray Leonard for speed. Muhammad Ali for wisdom.

This documentary breaks down why Stone Hands chose these five, what he saw in each of them, and why the name at number two is the one almost nobody expected.

From Hearns's devastating right hand to Monzón's icy calculation, from Hagler's refusal to lose to Leonard's quick-adapting mind, every pick reveals what Durán truly valued in a fighter.

Greatness, it turns out, is not a ranking or a record. It is a feeling, the moment you watch someone and cannot look away.
