As the old saying goes, "numbers don't lie," and in the case of the self-proclaimed, greatest boxer of all time, Floyd Mayweather has the statistical numbers of CompuBox to back up his claim.
Going off the numbers—which CompuBox president Bob Cannobbio calculated by fighter's bouts in their prime—they clearly show that Mayweather is on another level, as far as his number of punches landed compared to punches landed on him.
Money May leads both of the main categories that CompuBox calculates by averaging a 46 percent connect rate, as opposed to an astonishing 16 percent punched landed by his opponents on the 42-0 pound-for-pound great.
Mayweather's overall plus/minus number is plus-30 percent—subtracting the amount a fighter is hit from the amount a fighter lands punches—far ahead of any other top fighter, regardless of weight class.
Comparing Mayweather to other top fighters shows that Mayweather is the most efficient fighter that we have ever seen.
The closest opponent of the current crop of top boxers is current super middleweight champ Andre Ward in second with a plus-15 plus/minus ratio, just half that of Money May.
The rest of the top six is as follows: Vitali Klitschko at plus-13 percent, Yuriokis Gamboa at plus-12 percent, Manny Pacquiao at plus-11 percent, Timothy Bradley at plus-eight percent and Nonito Donaire at plus-seven percent.
The fighter of the modern era who gets the most debate when talking about who is the P4P great with Mayweather is Pacquiao.
Do the CompuBox numbers back up Floyd Mayweather's greatest of all time claim?
Pacquiao's power punch stat is 45.3 percent, just behind Mayweather's 47.8 percent, but Pacquiao gets hit more than Money May. A lot more.
Pac Man's opponents land punches on the Filipino fighter at an average of 33.6 percent, which means he takes more punishment than Money May who, as I stated before, gets hit by 16 percent of his opponents punches.
All this statistical evidence, along with Mayweather's unblemished record of 42-0 clearly shows that he is indeed the greatest fighter of the modern era and may also be the greatest of all time.
Compubox numbers show that legendary fighters of the past don't stand up to Mayweather with their statistical averages as well, as CompuBox calculated their scores by going back and watching tape of them in their primes.
Joe Louis is the closest with a plus-26 percent average, followed by Marvin Hagler with a plus-17 percent and Sugar Ray Leonard with a plus-13 percent. Roberto Duran with a plus-eight percent, Thomas Hearns with a plus-six percent and Muhammad Ali with a plus-four percent don't match up with Mayweather numbers-wise either.
The one fighter who many consider to be the best ever, Sugar Ray Robinson, didn't have any film of fights in his prime so he did not receive a number.
Sure the numbers can't tell the whole story as far who in fact is the greatest to ever take to the ring, but they have to mean something, and this will give Mayweather one more valid reason to keep on proclaiming that he is indeed the GOAT of boxing.
