3. Ali KO's Liston (II): The sneaky rabbit punch out of nowhere. Assuming you believe it was Ali, not the Mafia, that got to Liston, then this one was a testament to what great speed can do.
Ali vs Foreman ko was from barrage of punches i think this guy was asking whats 3 hardest punches you have seen connect meaning one punch not barrage of punches.

Liston was hit on the cheek by grazing blow it was fixed imo.
