Mike Tyson Names the Most Intimidating "Killer" in Boxing History

Ex-world heavyweight champion Mike Tyson believes that Sonny Liston, one of the greatest heavyweights of his time, is the most menacing figure in the history of boxing.

"Nobody thought [Muhammad Ali] would last two rounds with [Sonny] Liston, the most terrifying guy to ever step into the ring. He was a true killer. Before the fight with Ali, he held up two fingers, indicating he'd knock Ali out in the second round. But Ali defeated him," Tyson shared on his YouTube podcast.
