50 Greatest Boxers of the Last 50 Years

So, without further ado, here is my list of the 50 Greatest Boxers of the Last 50 Years, starting at the bottom 25 (No.’s 50-26).

2017 marked the 50th year anniversary of Muhammad Ali’s refusal of the draft. Looking back at this monumental time in history, we can only marvel at Ali–just 25 years and at the peak of his professional career–willing to sacrifice what would turn out to be more than three of his prime years to stand up for a fight he believed in.

Ali was immediately stripped of his championship title and his boxing license was suspended. He would later be reissued a license and the U.S. Supreme Court reversed his conviction for draft evasion. Muhammad would continue his amazing career and rivet the world as “The Greatest of All Time.”

Now, some 50 years later, does he still deservedly remain atop of the list of the greatest boxers during this time period? How does he fare against the likes of the recently re-retired Floyd Mayweather Jr., who was unquestionably the best boxer of this millennium?

Fellow boxing greats Andre Ward, Wladimir Klitschko and Juan Manuel Marquez also retired in 2017. Is it too early to put them in the conversation? Do they even make the list?

So, without further ado, here is my list of the 50 Greatest Boxers of the Last 50 Years, starting at the bottom 25 (No.’s 50-26).

A fast, technical boxer with exceptional combination and counter-punching ability. His most notable bouts include a four-fight saga with Manny Pacquiao and his rivalry with Marco Antonio Barrera. Only holds one win against Pacquiao–via a spectacular knockout victory–but many fans and experts believe he should have gone 4-0 against him.

40. Wilfred Benitez – Welterweight | Record: 53 wins (31 knockouts), 8 losses, 1 draw

39. Carlos Zarate – Bantamweight | Record: 66 wins (63 knockouts), 4 losses

A lanky boxer-puncher with tremendous power for a Bantamweight, he–along with fellow Mexican legend and 118-pound champion Ruben Olivares–were voted as the greatest Bantamweights of the 20th century by the Associated Press. The Ring magazine ranked him No. 21 among the 100 greatest punchers of all-time.

Zarate made nine successful title defenses, all by stoppages. All four losses, including a controversial one against former sparring partner Lupe Pintor, came against other great world champions (Wilfredo Gomez, Pintor, Jeff Fenech, Daniel Zaragoza).  Has the distinction of being the only boxer to put together two win streaks of 20 knockouts in a row.

36. Vicente Saldivar – Featherweight | Record: 37 wins (26 knockouts), 3 losses

Widely considered one of the three greatest Featherweights of all-time. Saldivar is also mentioned among the great southpaws in boxing history. The Mexican brawler was known for his vicious body attack and tremendous stamina. He won the WBA title and twice the WBC titles in the Featherweight division.

Among his three losses, one was due to disqualification which he later avenged and the other to fellow all-time great and hall-of-famer Eder Jofre.

35. Eusebio Pedroza – Featherweight | Record: 42 wins (26 knockouts), 6 losses, 1 draw, 1 no-contest

Initially overshadowed by his WBC counterpart Salvador Sanchez, whose title reign coincided with his from 1980 to 1982, the tall, hard punching Panamanian boxer holds the Featherweight division record for most successful title defenses at 19 and the longest title reign at seven years and two months.

He became the lineal title holder after the premature death of Sanchez. Pedroza was an aggressive boxer, often resorted to dirty tactics like throwing low blows to weaken and discourage his opponents and was known for mounting late rallies in fights to secure the victory.

Frequently mentioned among the greatest Welterweights of all-time. Napoles made 13 successful title defenses in two reigns as champion, which lasted nearly seven years.

His effortless, smooth boxing ability belied his punching power in both hands. His victims were often brutalized, as well as outclassed. Twice dominated world Welterweight champion Curtis Cokes, first to capture his title and also beat future hall-of-famer Emile Griffin. Jose was also one of the top Lightweights and Junior Welterweights of the 1960’s but unable to secure a title shot.

33. Felix “Tito” Trinidad – Welterweight | Record: 42 wins (35 knockouts), 3 losses

A lanky, aggressive puncher with explosive power and tenacity, Trinidad is frequently mentioned among the greatest and most beloved Puerto Rican boxers of all-time. Tito was also the best finisher in the sport during his career. He is a three-weight world champion: Welterweight, Super Welterweight, Middleweight.

He was never stopped in any of his five losses and only suffered one loss near his prime. Throughout the 1980’s, he was the most feared and avoided man in the sport.

Avoided by the likes of Sugar Ray Leonard, Thomas Hearns, Roberto Duran and Marvin Hagler. He withstood the vaunted punching power of future two-weight world champion Julian Jackson to quickly stop him in defense of his title and his chilling one-punch knockout of another former two-weight world champion Donald Curry remain etched in the annals of boxing as one of the most spectacular endings all-time. He is also known for his rivalry with James Toney in a clash for the Middleweight title.

31. Miguel Canto – Flyweight | Record: 61 wins (15 knockouts), 9 losses, 4 draws

The legendary Mexican boxer was a fast, elusive pressure fighter who overwhelmed his opponents with a high-punch rate. He also had tremendous defensive abilities, slipping and dodging punches with ease.

He beat former or future world champions like Betulio Gonzalez, Shoji Ojuma and Antonio Avela during his title reign.

30. Azumah Nelson – Featherweight | 39 wins (28 knockouts), 6 losses, 2 draws

The Ghanaian legend is widely considered the greatest African boxer all-time. A three-time world champion in two-weight divisions: Featherweight, Super Featherweight. A fast-handed puncher with thudding power, he was called “the Professor” for the lessons he would teach his opponents in the ring.

As a raw, last-minute replacement to face Salvador Sanchez, had the great champion on the brink of defeat, often outworking Sanchez in a see-saw battle before succumbing the Mexican legend’s powerful left hooks with seconds left in the 15th round.

Knocked out another legend, Wilfredo Gomez, to win his first world title at Featherweight. Known for rebounding well from losses or poor performances in rematches, including his other signature win: a knockout victory over three-weight champion Jeff Fenech, who got the better of Nelson in a prior meeting that resulted in a disputed draw.

29. Eder Jofre – Bantamweight, Record: 72 wins (50 knockouts), 2 losses, 4 draws

Considered by most boxing historians as the greatest Brazilian boxer of all-time, as well as the finest Bantamweight in the history of the sport.

His unbeaten streak and first title reign as world bantamweight champion had already come to an end by fellow hall-of-famer Fighting Harada in 1966, the only man to ever defeat Jofre as a professional.

His standing here is based on his accomplishments and abilities upon returning to the ring on August 27, 1969 after first retiring following back-to-back losses to Harada.

A superb stylist who fought out of a semi-crouch and had excellent punching power, he was a two-weight world champion: Bantamweight, Featherweight. Eder defeated Jose Legra at the advanced age of 37, to win the WBC and lineal featherweight title.

He successfully defended that title once, against fellow hall-of-famer Vicente Saldivar in a battle of two all-time greats, scoring a 4th round knockout. The Brazilian legend went an incredible 25-0 with 12 coming by stoppage to end his career at the age of 40.

28. Bob Foster – Light Heavyweight | Record: 56 wins (46 knockouts), 8 losses, 1 draw

One of the greatest Light Heavyweights of all-time, the tall, lanky American boxer was also considered one of the most feared and devastating punchers in the division’s history. Won the world Light Heavyweight title by knocking out the great Dick Tiger in Round 4 with a tremendous left hook, his signature punch. It was the only time Tiger was ever stopped. Foster successfully defended the title 14 times, a division record at the time.

Prior to his last two defeats to end his career, all but one of his 6 other losses came against Heavyweights, including boxing immortals, Joe Frazier and Muhammad Ali. A round 4 knockout of Mike Quarry to defend his title, along with the Tiger win, are chilling reminders of how powerful Foster was at Light Heavyweight.

27. Wilfredo Gomez – Jr. Featherweight | Record: 44 wins (42 knockouts), 3 losses, 1 draw

Frequently mentioned among the greatest Puerto Rican boxers of all-time and universally considered the best Super Bantamweight (Junior Featherweight) in history. A three-weight class world champion: Super Bantamweight, Featherweight, Super Featherweight. One of the most prolific punchers ever.

His 17 consecutive knockouts in world title defenses is a record in boxing. The 17 successful title defenses is also a Junior Featherweight division record. Gomez’s streak reached 33 knockout in a row, a record for world titleholders.

One of those knockouts included a five-round defeat of world Bantamweight champion and fellow hall-of-famer Carlos Zarate, who was 55–0 with 54 knockout wins going into the fight. Gomez failed in his first attempt to win the world Featherweight title, losing by eight-round stoppage to the great Salvador Sanchez and suffering his first loss.

After the loss, returned to dominate the Junior Featherweight division, including his last title defense against another great Bantamweight champion, Lupe Pintor, whom he stopped in round 14.

Wilfredo’s other two losses came against Ghanaian legend Azumah Nelson and Alfredo Layne when he was well past his prime, both in title losing efforts of his Featherweight and Junior Lightweight titles, respectively.

26. Gennady Golovkin – Middleweight | Record: 38 wins (34 knockouts), 0 losses, 1 draw (career active)

The powerful Kazakh has recently been elevated to the No. 1 pound-for-pound boxer in the world by The Ring magazine following his first superfight, a disputed draw that most ring-siders and fans felt he edged out over current fellow superstar Canelo Alvarez, and the retirement of Andre Ward.

Golovkin is a calculated pressure fighter known for his precise power punching and methodical movement. He holds the highest knockout percentage (89.8%) in Middleweight history and his 17th title defense by knockout equalled the record set by Wilfredo Gomez. His chin is considered one of the best in modern boxing history.

With his draw against Alvarez, Golovkin earned his 19th successful title defense, which was one behind Bernard Hopkins (20) for most in division history.

On May 5, 2018, Golovkin tied Hopkins’ title-defense record at 20 with a second-round stoppage of Vanes Martirosyan.

2017 marked the 50th year anniversary of Muhammad Ali’s refusal of the draft. Looking back at this monumental time in history, we cannot but marvel at Ali–just 25 years of age and at the peak of his professional career–willing to sacrifice what would turn out to be more than three of his prime years to stand up for a fight he believed in.

Ali was immediately stripped of his championship title and his boxing license was suspended. He would later be reissued a license and the U.S. Supreme Court reversed his conviction for draft evasion. Muhammad would continue his amazing career and rivet the world as “the Greatest of All Times.”

Now looking back some 50 years later, does he still deservedly remain atop of the list of the greatest boxers during this time period? How does he fare against the likes of the recently re-retired Floyd Mayweather Jr., who was unquestionably the best boxer of this millennium?

Was there someone greater than them both? Fellow boxing great Andre Ward also retired in 2017, while Manny Pacquiao continues on with his career. Is it too early to put them in the conversation? Do they even deserve to be near the top of the list?

25. Khaosai Galaxy –  Super Flyweight | 47 wins (41 knockouts), 1 loss

One of the greatest boxers from Asia. This Thai boxer was known for his exceptional strength and punching power. He fought out of a southpaw stance and relentlessly pursued his opponents around. Thickly muscled, he was surprisingly quick on his feet and capable of throwing fast combinations. In his sixth professional fight, Galaxy was decisioned by Sakda Saksuree. It would be the lone loss of his illustrious career.

Galaxy knocked him out in the rematch. Galaxy knocked out Eusebio Espinal in round 6 to win the vacant WBA Super Flyweight title and defended it 19 times, including 16 by knockout and reigned over seven years. Both accomplishments are records in the division. His powerful left hand was responsible for most of his knockouts and is considered by many the hardest single puncher in the history of the lightest weight divisions. Among his victims was future WBA Bantamweight champion Israel Contreras.

24. Andre Ward – Light Heavyweight | 32 wins (15 knockouts), 0 losses

An American boxer who won eight world titles in two-weight classes: Super Middleweight, Light Heavyweight. Ward was also the 2004 Olympic gold medalist in the Light Heavyweight class. He defeated Mikkel Kessler to win the WBA Super Middleweight title and WBC champion Carl Froch to unify the super middleweight titles and win the lineal title. Successfully defended those titles against lineal Light Heavyweight champion Chad Dawson, scoring a 10th round TKO.

Ward later moved up in weight and beat Sergey Kovalev to win the unified Light Heavyweight titles. Many boxing historians now consider Ward one of the greatest super middleweights of all-time, along with Roy Jones and Joe Calzaghe. An intelligent, versatile, well-rounded boxer with an underrated left hook. Ward stunned the boxing community when he suddenly retired in 2017 as the No. 1 pound-for-pound boxer according to The Ring magazine and as an undefeated world champion.

23. Thomas Hearns – Jr. Middleweight | 61 wins (48 knockouts), 5 losses, 1 draw

This American boxer was at his best as a tall, lanky boxer-puncher as a Welterweight and Super Welterweight. Considered by many to be the hardest punching Welterweight of all-time. His excellent boxing skills, hand-speed, long reach, stiff left jab and powerful right cross helped him become the first boxer win world titles in 5 different weight classes.

Scored a round 2 TKO of WBA Welterweight champion Pipino Cuevas and made three successful title defenses, suffering his first loss at the hands of WBC champion Sugar Ray Leonard in a title unification match. Rebounded by moving up in weight and capturing the WBC Super Welterweight title from fellow hall-of-famer Wilfred Benitez by majority decision. Made three successful title defenses, including a spectacular second KO of the legendary Roberto Duran.

22. Aaron Pryor – Jr. Welterweight | 39 wins (35 knockouts), 1 loss

An American boxer who was a two-time Super Lightweight world champion, including the Ring magazine and lineal titles. Pryor was a hard-punching, fast handed boxer who fought in ferocious, relentless manner. A 26 fight win streak, all by knockout, led to a title match against two-time world champion Antonio Cervantes for the WBA Junior Welterweight title. After being knocked down in Round 1, Pryor knocked out Cervantes in round 4 to become champion.

He successfully defended the WBA and IBF titles, respectively, a total of 10 times. Two of those successful title defenses was against fellow hall-of-famer Alexis Arguello, who was attempting to become the first man to win world titles in four different weight divisions and was a 12-5 betting favorite. In a classic battle, Pryor was stunned repeatedly in a brutal, see-saw battle before prevailing in Round 14. He came out quickly in the round and landed a barrage of unanswered punches on Arguello that prompted the referee to stop the fight. The Ring magazine named it the Fight of the Decade for the 1980’s.

The rematch was another action-packed affair but, this time, Arguello succumbed to Pryor’s pressuring attack in round 10. An eye injury and drug abuse led to his first retirement. A shell of his former self, Pryor attempted a comeback which led to the only loss of his career at the hands of journeyman boxer Bobby Joe Young by knockout in round 7. Was voted by the Associated Press as the world’s best Light Welterweight of the 20th century.

21. Joe Frazier – Heavyweight | 32 wins (27 knockouts), 4 losses, 1 draw

Frazier scored a four-round TKO over WBA champion Jimmy Ellis in a title unification match to become the undisputed Heavyweight champion.

He followed it up with a unanimous decision win over the comebacking Muhammad Ali in their much anticipated match billed the “Fight of the Century” to become the lineal champion, but shockingly lost the title to George Foreman by Round 2 TKO.

He had one last attempt to recapture the world title, losing to Ali in their rubber match, billed as the “Thrilla in Manila.” Ali scored a round 14 TKO in a brutal war. Suffered another stoppage loss to George Foreman to end his status as a top tier Heavyweight. Only losses came at the hands of fellow hall-of-famers Ali and Foreman, who defeated him twice each.

20. Ruben Olivares – Bantamweight | 89 wins (79 knockouts), 13 losses, 3 draws

After making nine successful title defenses, was knocked out in round 10 by 49-1 underdog Buster Douglas in the biggest upset in boxing history. In 1992, Tyson was convicted of raped and sentenced to six years in prison, ultimately released after serving 3 years.

Tyson regained the WBC and WBA titles by defeating Frank Bruno and Bruce Seldon respectively. He lost the WBA title (after being stripped of the WBC belt) by stoppage in round 11 to Evander Holyfield in another huge upset. In their infamous rematch, Tyson was disqualified for biting both Holyfield’s ears. A vastly depleted Tyson had one last attempt to regain the world title, losing to Lennox Lewis after being knocked out in Round 8.

One of the most feared fighters in history, Tyson fought out of a tight, highly guard, peek-a-boo style and was known for his tremendous punching power and hand speed. He possessed a particularly fast, devastating uppercut and left hook, and was well adept at unleashing quick, powerful combinations and excellent at slipping his opponents’ punches in his prime. Ring magazine ranked Tyson No. 16 on their 100 Hardest Punchers of All-Time and ranked him No. 1 on The Hardest Hitters in Heavyweight History.

18. Lennox Lewis – Heavyweight | 41 wins (32 knockouts), 2 losses, 1 draw

He retired shortly after the fight.

17. Michael Spinks – Light Heavyweight | 31 wins (21 knockouts), 1 loss

One of the greatest Light Heavyweights in history. This American boxer first won a gold medal as a Middleweight at the 1976 Olympic games. Spinks was a world champion in two different weight classes as a professional: Light Heavyweight, Heavyweight. He was the first reigning Light Heavyweight champion to successfully move up and win the Heavyweight crown. A lanky, awkward but intelligent boxer-puncher that yielded tremendous punching power in his right hand, which was dubbed “the Spink Jinx.” Spinks used his cagey, unorthodox boxing skills and power to win the WBA Light Heavyweight title from Eddie Mustafa Muhammad. He then unified the titles by decisioning WBC champion Dwight Qawi. After 10 successful title defenses, Spinks challenged Larry Holmes for the IBF and lineal Heavyweight titles. A huge underdog, Spinks scored a unanimous decision win over Holmes to become Heavyweight champion and denied Holmes the chance of tying Rocky Marciano’s unbeaten record of 49-0.

His first attempt to regain the world title ended in defeat, a decision loss to undisputed world Heavyweight champion Evander Holyfield in surprisingly competitive battle.

13. Salvador Sanchez – Featherweight | 44 wins (32 knockouts), 1 loss, 1 draw

This Mexican boxer was the WBC and lineal Featherweight champion and many experts predicted, had it not been for his premature death resulting from a fatal car crash, he would have gone on to become the greatest Featherweight of all-time. Sanchez defeated Danny “Little Red” Lopez by round 13 TKO to win the WBC featherweight title and made 9 successful title defenses, including signature wins over fellow hall-of-famers Wilfredo Gomez and Azumah Nelson. Known for his great stamina, granite chin, punching accuracy and exceptional power.

His last fight was against a young and hungry Nelson, withstanding tremendous bombs throughout the fight to outlast Azumah, scoring a round 15 TKO. Three weeks later, Sanchez was tragically killed in an auto accident at the young age of 23.

12. Alexis Arguello – Jr. Lightweight | 77 wins (62 knockouts), 8 losses

This lanky, hard-punching Nicaraguan boxer was a three-weight world champion: Featherweight, Super Featherweight, Lightweight. Many experts consider Arguello the greatest Featherweight of all-time. A calculated boxer with tremendous power in the fashion of Joe Louis. Arguello won the WBA Featherweight title with a Round 13 knockout of fellow hall-of-famer Ruben Olivares.

It was his knockout of Ray Mancini in defense of his WBC Lightweight title, however, that made Arguello a household name in America. He never lost any of his world titles in the ring. Arguello may be best known for twice challenging Aaron Pryor for the WBA Super Lightweight title, losing both in brutal, action-packed battles.

Chavez captured the WBC and lineal titles as well by defeating Jose Luis Ramirez and later the WBC, IBF, WBO and lineal Super Lightweight titles. Known for his hard-punching, pressuring style and tremendous body attack, Chavez also had a granite chin and considered one of the most durable boxers in modern day history.

His signature wins include coming from behind to stop the previously unbeaten IBF Super Lightweight champion Meldrick Taylor in a title unification fight and dominating WBO super lightweight champion Hector Camacho in their highly anticipated fight.

His classic battle with Thomas Hearns resulted in a third round knockout victory and is still considered one of the greatest title fights ever.

Hagler was a rugged, pressuring, versatile boxer-puncher with one of the best chins in boxing history. He was denied the opportunity to break the then record for most Middleweight title defenses (held by Carlos Monzon at 14) with a shocking defeat at the hands of a returning Sugar Ray Leonard via disputed majority decision. Hagler retired after the fight and never made a comeback.

Defeated Greg Haugen for the IBF title by 12 round unanimous decision. Gained some revenge by defeating Ramirez by a resounding shutout decision to win the WBC title in his second try, and unified the Lightweight titles by scoring a Round 1 knockout over WBA champion Juan Nazario.

In what should have been his most signature victory, Whitaker had to settle for a controversial draw against WBC Super Lightweight champion Julio Cesar Chavez in defense of his WBC Welterweight title and the mythical pound-for-pound title when 2 of the 3 judges scored their fight a draw.

Most ringsiders felt Whitaker earned a clear cut victory. He lost his title in another close, disputed decision at the hands of Oscar DeLaHoya. By then, age and drug abuse began to take its toll on Whitaker’s incredible skills. He suffered his first non-controversial loss in a decision to Felix Trinidad for the WBA Welterweight title.

5. Roy Jones Jr – Super Middleweight | 66 wins (47 knockouts), 9 losses

This American boxer has a dual Russian citizenship. Jones was a six-time world champion in four different weight classes: Middleweight, Super Middleweight, Light Heavyweight, Heavyweight.

Then, three years later, Leonard shocked the world by defeating Marvin Hagler by split decision to win the undisputed world Middleweight title.

He would go on to win the WBC Super Middleweight and Light Heavyweight titles. A brilliant ring strategist with tremendous hand speed, heart and good punching power, Leonard was also very durable and a great finisher when he hurt his opponents. His battles with the fellow legends brought relevancy in the lower weight divisions and made him the most popular and richest boxer after the post-Ali era. Leonard made several comebacks after retiring, losing his last two fights.

3. Roberto Duran – Lightweight | 103 wins (70 knockouts), 16 losses

This Panamanian boxer was called Manos de Piedra (Hands of Stone) because of his devastating punching power. Duran was a pressuring, versatile brawler with tremendous in-fighting skills and the ability to slip punches. He was a four weight world champion: Lightweight, Welterweight, Super Welterweight and Middleweight.

Buchanan was unable to continue in a fight Duran had dominated from the opening seconds. His signature win was a 15-round unanimous-decision victory over Sugar Ray Leonard for the WBC Welterweight title.

Duran masterfully outmaneuvered and roughed up Leonard, handing Sugar Ray his first loss as a professional. Duran surrendered the title six months later in the rematch, uttering the infamous words, “no mas” (no more in Spanish) after being mocked and embarrassed after Round 7 in a closely contested fight. Leonard was awarded a Round 8 TKO. Duran was able to rebound from the loss and initial failed attempts to claim the Super Welterweight and Middleweight titles, including winning the WBA Junior Middleweight (Super Welterweight) title from Davey Moore and then WBC Middleweight title at the age of 39 by scoring a majority decision win against Iran Barkley.

Duran had previously lost to Marvin Hagler for the undisputed Middleweight title, giving the much bigger, stronger Hagler one of the toughest fights of his career. The Associated Press ranks Duran as the greatest Lightweight of all-time. In 2002, the Ring magazine ranked Duran the fifth best boxer of all-time.

2. Floyd Mayweather Jr – Lightweight | 50 wins (27 knockouts), 0 losses

He was also the lineal champion in four weight classes and, as an amateur, earned a bronze medal as a Featherweight at the 1996 Summer Olympics. ESPN named Mayweather the greatest boxer, pound for pound, of the last 25 years in 2016.

BoxRec currently ranks him the No. 1 fighter of all-time and the greatest Welterweight ever. He is often recognized as the best defensive fighter in boxing history and the most accurate puncher since the existence of CompuBox. His patented shoulder-roll technique, exceptional hand speed, counter punching ability, lead right cross and ring intelligence all helped him finished his career with a record of 50-0, beating Rocky Marciano’s unbeaten record of 49-0.

The richest boxer in history, his fight against Manny Pacquiao–the highest grossing and most anticipated sporting event of the 21st century–earned him more than half of the reported 400 million in revenue the fight generated and his unanimous-decision win firmly cemented his place as the best boxer so far in this millennium. Mayweather made a record 26 consecutive wins in world title fight, 24 wins against former or current world titlists, 12 wins against former or current lineal champions, and 2 wins against hall-of-famers (Oscar DeLaHoya, Arturo Gatti).

1. Muhammad Ali – Heavyweight | 56 wins (37 knockouts), 5 losses

This American boxer is the first to win the world Heavyweight title three times and remains the only three-time lineal champion. As an amateur, he was the 1960 Olympic gold medalist in the Light Heavyweight division. After shocking the sports world by defeating the supposedly invincible Sonny Liston by Round 7 TKO, Cassius Clay–who had recently converted to Islam–changed his name to Muhammad Ali.

Three years after winning the title, Ali was striped of his crown for refusing to be drafted into the U.S. military, citing his religious beliefs and opposition to American involvement in the Vietnamese War. He was arrested and charged with draft evasion. He successfully appealed to the U.S. Supreme Court, which overturned his conviction. By then, Ali lost nearly four years of his athletic peak performance period. His first try to regain the title resulted in a unanimous decision loss–his first defeat as a professional–at the hands of Joe Frazier in the “Fight of the Century.”

Three years later, Ali successfully completed his comeback from exile, scoring another huge upset by knocking out champion George Foreman in Round 8 to reclaim the Heavyweight title. After losing the title to the unheralded Leon Spinks, Ali defeated him six months later to become the lineal Heavyweight champion a record third time.

He retired shortly thereafter but then launched an ill-fated comeback, losing WBC champion and former sparring partner Larry Holmes by Round 11 TKO–his first and only stoppage loss. Ali beat every top Heavyweight of his era, which is still considered the golden era of boxing and was involved in several historical and classic battles–including his terrific trilogy with Frazier and Ken Norton, and battles with Liston, Foreman and Earnie Shavers.

In the 1960’s, Ali relied on his unparalleled hand and foot speed for a big man, superb reflexes and constant movement to dodge punches, throwing fast combinations and dancing away from danger. In the 1970’s, a much slower version of Ali utilized his excellent ring generalship, intelligence, counter right cross and exceptional toughness and durability to outthink or outlast opponents.

The Ring magazine named Ali the No. 1 Heavyweight of all-time in 1998, the No. 3 best pound-for-pound boxer of the last 80 years (behind only Sugar Ray Robinson and Henry Armstrong) in 2002, and named him the Fighter of the Year a record six times. Sports Illustrated and ESPN both named Ali the Athlete of the 20th Century in 1999.
