Barerra 1 was a huge huge win. Barerra was in ABSOLUTE PRIME. He'd just destroyed Prince Hamed and revenged his loss against Morales. BUT the Cotto win is his best, due to the size factor and the opponent Cotto faced. Cotto ducked NO ONE and had wins over Mosely, Judah and fought THE BEST in the division. People need to understand the what Manny has acheived by beating Cotto.
Barerra it brought him into the scene. American fans were introduced to him. It was a major upset. And set the tone for the rest of his career as a very serious fighter.
BArrera. He didnt beat him. He ambushed him. He abused him..no he actually raped him. It gave us a glimpse of a future top 10 ATG.
Mab I Barrera was prime, a top 3 P4P fighters, Pac was moving up in weight, Pac was about a 3.5 to 1 underdog and made Mab look like a bum who didnt belong in the ring with him.
Barrera I, by far the biggest win of his career. See Boom_boom's reply for explanation. What Pacquiao has done recently is nothing short of otherworldly, but Barrera I is still the biggest win on his resume. Probably the biggest win on the resume of any active fighter today.
