JUGGERNAUT:a huge, powerful overwhelming force or institution. The true definition of the word. FITS LISTON PERFECTLY!
What makes you think Tyson hit harder than Williams? Most common opponents (and Liston himself) say Williams hit harder than Liston. Liston also hit harder than young Foreman (who himself says Williams hit harder than Liston) per all common opponent. Not 1 common opponent of Foreman and Tyson say Tyson hit harder. Not one. And this was an OLDER Foreman who'd lost a good amount of speed, power, and explosiveness. So it goes like this Williams>Liston>Young Foreman>Old Foreman>Tyson.
