No matter where you look to compile a list of the world’s greatest boxers, the top ten are usually from the Americas, are usually middleweight to heavyweight, and the author’s personal selection. Here are just a few I consider should be in history’s list of greatest boxers – in no particular order.Joe Louis is a boxer you will find in every list, anywhere in the top-ten. He held the world heavyweight title for a full 12 years from 1937 to 1949. With the slow run up to the Second World War under way, he lost to Max Schmeling in 1936. Having gained the world heavyweight crown in 1937 he annihilated Schmeling in a rematch, with a round one knockout in 1938. In his 12 years as champion he successfully defended his title 25 times.Mohammad Ali, who wouldn’t have good old Cassius Clay, as was before his conversion to Islam, in their top ten. He who said he would ‘float like a butterfly and sting like a bee,’ and that he did. He turned the rules of boxing upside down, and was the rings first real showman. In a career spanning 1960 to 1981 he fought 61 fights, losing 5 and recording 37 knock-outs out of his 56 wins. If there is any downside to his career it’s that he should have retired earlier.Sugar Ray Robinson, is regarded by many as the best boxer of all time. With a career spanning 25 years from 1940 to 1965, he gained the world crown at both welterweight and middleweight. He had a record 173 wins during his career at both weights. Of those, 109 were knock-outs. Six fights were drawn, and 2 declared no contest fights. He is still considered one of the most ferocious fighters of all time.
