10 Most Career Knockouts in Boxing History

10 Most Career Knockouts in Boxing History Please support my channel. It can buy me another cup of coffee :) The knockout is the crescendo of a boxer physically, mentally, and emotionally dominating his opponent in the ring, and the spectacle of seeing one of the toughest guys in the world dropped to the mat with one punch never gets old. These boxers, who come from a variety of time periods and weight classes, epitomize the brutality of the knockout and still stand as some of the most dominant forces ever to step in a ring. Most fighters nowadays would be lucky to even get in the ring half as many times as these guys have knockouts. The first half of the 20th century, when the top four fighters spent most or all of their careers, was a strange time for boxing. That just means special congratulations are in order for Buck Smith, who fought from 1987 to 2009.
