Manny Pacquiao is not just a fighter but a pugilistic genius. Not just a man but a megastar and a hero to his people.
On April 14 at the MGM Grand Garden Arena in Las Vegas, "Pac-Man" will square off with pound-for-pound star Timothy Bradley in a rematch of their blunder of a decision in June 2012. Pacquiao looks to add to a legacy that already places him amongst the sport's very greatest combatants.
Since turning professional at the age of 16, he has come a long, long way. The sport has seen him grow from a 106-pound strawweight into an eight-division world champion.
Scaling weight like this has become an essential part of defining a boxer's legacy. But weight climbing, like boxing itself, is about whom you defeat and not just the literal weight ascended.
Pac-Man is the greatest weight climber of his time not only because of the pounds gained but the quality of competition that he has faced.
But just where does this modern-day great rank all time? Does his astonishing collection of belts in eight different weight divisions outshine the weight-climbing exploits of every legend of yesteryear? In a sport with such a deep history, it would be great to find out.
So here is Bleacher Report's stab at it.
