Pacquiao's evolution: From beanpole to brawler, wild man to warrior
When Manny Pacquiao steps into the ring on Saturday (Sunday, PHL time) against Timothy Bradley, he will be far removed from the teenager who made his professional debut in 1995. The Sarangani rep has gone from 98-pound, one-dimensional puncher to the chiseled ring maestro who headlines the MGM Grand Garden Arena. The eight-division champion As the story goes, a teenaged Pacquiao weighed a mere 98 pounds, well under the 105 pound floor for the minimumweight division. To meet the catchweight, Pacquiao slipped steel into his pockets during the weigh-in, bringing him up to 106 pounds for his debut bout against Edmund Ignacio, which he won by unanimous decision, back in January of 1995. Since then, Pacquiao has been packing more heft and more muscle to his 5'6.5" frame, with a few huge jumps along the way as he moved up from flyweight to bantamweight to featherweight, to where he is now, welterweight. The chart below displays some of the highlights of Pacquiao's growth. With the Pacman clocking in at an all-time high of 147 pounds at his weigh-in Friday (Saturday morning, PHL time), could that possibly have an effect when he fights Bradley, who weighed in at a pound less?
