Win or lose tonight, Manny Pacquiao is one of the greatest pound-for-pound boxers the world has ever seen.
He has been absolutely incredible over the past five years, winning every bout he has taken part in. His last loss came all the way back in 2005, when he lost a unanimous decision against Érik Morales.
Since then, he has gone on a rampage through the boxing world. He has knocked out Ricky Hatton, Oscar De La Hoya, and Miguel Angel Cotto during that span. No one has been able to hang with Pacquiao during that span.
The only guy remaining on his list to defeat is Floyd Mayweather. Money has never lost a bout in his professional career, which makes him the de facto best fighter in the world. Nevertheless, Pac-Man is right there with him, and might actually be the better boxer.
A victory over Mayweather is the only thing left for Pacquiao to do in his career. If he can finally workout an agreement with Money, he can prove once and for all that he is the best pound-for-pound boxer the world has ever seen.
Pacquiao could hang with nearly every great boxer of any era outside of the heavyweight class. All he needs to solidify his status as the best pound-for-pound boxer of all-time is a victory over Floyd Mayweather.
