#19: Floyd Patterson
Patterson’s toughness was rooted in his resilience. Though known for speed and skill, he also showed immense heart, repeatedly rising from knockdowns and coming back stronger. He faced criticism and humiliation yet never lost his fighting spirit. Patterson’s ability to endure setbacks and keep battling defined his unshakable toughness.

In 1960, Patterson faced Ingemar Johansson in their rematch. After being brutally knocked out by Johansson the year before, Patterson returned determined, absorbing heavy shots and unleashing his own power to win by fifth-round knockout. That comeback showed Patterson’s grit — conquering fear and regaining his title through sheer willpower.
