Teddy Atlas has given named his top ten all-time greatest boxers, placing heavyweight icon Muhammad Ali at number four. Ali became the first man to win the world heavyweight championship on three seperate occasions, and beat the likes of George Foreman, Joe Frazier, Sonny Liston and Floyd Patterson. That includes Atlas, who gave Ali the 4th spot in his all-time list. He fought across nearly every weight class and historians argue that Langford’s skill, durability, and knockout power place him among the greatest boxers never to win a world title. Robinson was the first fighter to win the world middleweight title five times and is widely hailed as the pound-for-pound greatest.
