Boxing fans surely have marked May 2, 2015 on their calendars following Floyd Mayweather's announcement on Friday that he is accepting Manny Pacquiao's challenge to meet on the ring.

Besides picking a date, Money May also reiterated to the Filipino champ that he should get the bulk of the guaranteed purse - speculated at $100 million - because Pacquiao has two losses while he is still undefeated.

With his 0 loss record, Mayweather seems to have the upper hand and is likely the bettor's favourite. A number of boxing experts believe Money May has the advantage and always point to his being undefeated to bolster their claim that he, and not Pacquiao, is the undisputed pound-for-pound king.

However, two articles dispute that claim and cited statistics to prove that it is the eight-division title holder who is the superior boxer and not the five-division champ.

The Wall Street Journal's Josh Katzowitz went over the stats of boxers whom Pacquiao has beaten, and his conclusion is that for most of them, their life as a pugilist was never the same after battling the southpaw on the ring.

The most prominent of the 13 boxers that Katzowitz listed is boxing's golden boy, Oscar de la Hoya, who retired from boxing after Pacquiao won over him in just eight rounds in December 2008. Ricky Hatton, whom Pacquiao knocked out in Round 2 in May 2009, just fought one more fight and then hang his gloves.

But there are some exceptions such as Miguel Cotto, whom Pacquiao beat in November 2009, but Cotto won 5 of his next 7 fights. Of course, Mexican boxer Juan Miguel Marquez whom Pacquiao beat twice, gave the Filipino champ one of his 5 losses.

The second proof comes from fight analyst David Phillips who wrote in Sweet Science that Pacquiao's punches has higher volume. He pointed out that while Money May could dodge most of Pacquiao's punches, judges would likely give more points to the latter's aggression and activity than the former's dodging prowess.

Another point in favour of the Filipino boxer is that he has done extremely well against boxers whom Mayweather had beaten. Pacquiao won over Oscar de la Hoya in 8 rounds, while Mayweather won by split decision. Pacquiao KOed Ricky Hatton in 2 rounds, but Mayweather took 10 rounds. Pacquiao also won by Technical KO versus Miguel Cotto, while Money May won by unanimous decision.

Phillips concluded, "Floyd's just never seen anything like Manny before. A quick drawing, powerful volume puncher, who is both highly skilled and highly unorthodox. He will be challenged."

Of course, Mayweather fans would believe that their idol would retire unbeaten, while Pacquiao's followers think otherwise. The only thing that would settle who deserves the pound-for-pound title is the two meeting on the ring and giving their best punch.

Unless Pacquiao's mum, Dionesia, unleashes her "hex" and gives her son undue advantage over Mayweather.
