20 Best Boxers of All Time

Boxing is arguably the most difficult and brutal game, with limited restrictions or rules. Boxing is played at both amateur and professional levels. Amateur boxing is seen at the collegiate, Olympic, and commonwealth games level, with bouts limited to three to four rounds. On the contrary, professional matches include World Championships with long bouts having ten to twelve rounds.

The boxing championships are divided into different categories based on the weight of the boxer. These categories include flyweight being the lightest of all at the 108-112 lbs. range. The other categories in order of increasing weight are featherweight, lightweight, welterweight, middleweight, light-heavyweight, and finally the heavyweight with a weight range of over 200 lbs.

Pound-for-pound rankings are released to resolve this issue, which takes the performance relative to weight. There are four major sanctioning bodies for professional boxing: World Boxing Association (WBA), World Boxing Council (WBC), International Boxing Federation (IBF), and World Boxing Organization (WBO). Each one of these sanctioning bodies has its own championships and winners and hence release their own rankings.

There is no central body that releases the rankings like the International Cricket Council (ICC) in the case of cricket. Some sports companies like ESPN (the brand of the Walt Disney Company (NYSE: DIS)), The Ring, and BoxRec release their rankings. But these rankings are based on the performance of boxers, their defeats, the quality of wins measured by knockouts and skills, hence highly subjective.

The new boxers of the 21st century are good in their game, but they have not gained the fame which boxers from the 20th century. One of the main reasons behind this is the decline in the number of people watching this sport. For example, the number of viewers watching boxing on HBO has decreased from 1,051,000 in Q1 of 2014 to 551,000 in Q1 of 2017. The effects of COVID-19 are the most devastating on boxing than any other sport. The viewership for Premier Boxing Champions has decreased up to 36% from 1.39 million viewers in Aug. 2019- Mar. 20 to  887,000 viewers in Aug. 2020- Mar. 21.

Our Methodology

Compiling the list of the best boxers of all time is a subjective matter and cannot be explained solely by the number of wins. For this list, we have taken four main components as criteria for ranking: in-ring performance, achievements, dominance, and mainstream appeal. In-ring performance is gauged by the number of matches played, how the fight has been played, and whether the wins are knockouts or not. Achievements include championships, how long the championships are defended, and any special titles like the “boxer of the decade.” Dominance and mainstream appeal are the factors that players from the 2oth century have enjoyed the most. Players like Muhammad Ali have a very strong public appeal that cannot be ignored. Although many of today’s boxers have better performance in the boxing ring, they might not have the same respect and fame as Muhammad Ali or Sugar Ray Robinson. Hence this list does not include the greatest of today but the boxers who were the greatest in their time.

Each boxer in the list has two, three, or four numbers written after their name as (A-B-C-D). These numbers show wins, losses, draws, and no contest.

So, without further delay, let’s explore the 20 best boxers of all time.
