Barrera at 1994-1995 at 100%, vs Pacquiao at his best at 122-126. IMHO Barrera in the 90's would be to much for Pacquiao, and especially the Barrera who beat Morales. I got Marco Antonio Barrera via TKO in the 10th or 11th.
Barrera at any stage in his career doesn't have the skills to outbox Pac. He's going to get caught and caught a lot at Pac's best weight.
Pacquiao would beat Barrera silly in any era. Barrera admitted himself he couldn't deal with Pacquiao's punching power in the first fight, and in the second fight he literally ran to survive to the entire 12 rounds.
Same result as the first fight. MAB is no way near shot after the first one - he strung a several good wins after that fight.
Crazy. Mexican madness are really coming out lately. They are just waiting all this time from day one to **** on Pac. They are truly bitter that their heroes suffered from the hands of Pacquiao.
Barrera simply cannot deal with the speed and unpredictability of the young Pacquiao. What's more, Barrera's style from the mid 90s was much more prone to getting hit and raw than he was later, see the fights with Kennedy McKinney and Junior Jones for example. And Pacquiao can take the punishment coming back a hell of a lot better than those guys can.
