Manny Pacquiao’s series of jumps from different boxing divisions is evoking an era in boxing history when boxers can choose to fight almost any other fighter regardless of weight differences.

According to sports analyst Ed Tolentino, Pacquiao’s ability to move into various weight divisions is following a precedent in the sport of boxing set by American Henry Armstrong, a boxing hall of famer.

“By tradition, boxers have a comfort zone, ito yung timbang nila na sa kanilang pananaw yung kanilang reflexes are so fast at yung mga suntok nila pulido,” said Tolentino in an interview over dzMM’s Sport’s Talk.

Tolentino, however thinks, Pacquiao is a different fighter.

“With Manny Pacquiao, he’s reviving the Henry Armstrong era wherein weight is just another pound. Kumbaga, kaya niyang i-prove na kung tatanggalin ang timbang, he can fight anybody in the business,” he said.

Henry Armstrong, whose real name is Henry Jackson Jr., is the only fighter in boxing history to simultaneously hold three world titles in three separate divisions.

Armstrong dominated the boxing scene in the 1930’s, wherein he beat Barney Ross, who is also a veteran of multi-division fights.

“In the last year, we saw Pacquiao grow from 130, 135, 147 [pounds] and now he’s going down to 140,” said Tolentino. “Ito ang special kay Manny, parang hindi barrier sa kanya ang timbang.”

For boxing historian Bert Sugar, Pacquiao may very well join the likes of Armstrong and boxing great Alexis Arguello, should the Filipino win over Ricky Hatton.

"The reason being -- it's not only difficult to leapfrog these many weight classes, but because you have equaled and passed greats like a Henry Armstrong, greats like Alexis Arguello. The way he has done it, we still don't know his true fighting weight,” said Sugar on ESPN.com.

“I make him out to be the greatest Asian fighter of all time, and conceivably, one of the greatest fighters of all time if he can carry this [Hatton fight] off,” said Sugar.

Pacquiao has already won the World Boxing Council (WBC) lightweight, the WBC super featherweight, the International Boxing Federation (IBF) super bantamweight, and the WBC flyweight world titles.

He also became the lineal featherweight champion when he beat Marco Antonio Barrera in 2003, though he never held a sanctioning belt in that division.

In fighting Hatton, Pacquiao attempts to win the International Boxing Organization (IBO) and the Ring Magazine junior welterweight titles plus another linear championship.
