Until the knockout was the fourth fight Pacquiao's best against Marquez?

could have been. It was almost like Hearns again Barkley. When Hearns opened up on Barkley he looked the best but he was open to counters. Somehow every great has a weakness. Hearns had Barkley and Pacman had Marquez.

 

it was only the 5th round when he was knocked out and he didn't have Canelo almost knocked out. So I don't know how much he was winning.

 

Oh yeah, agreed... hence the speech marks around 'winning'. But people here make a deal of how Khan did in the first four rounds when, in reality, Canelo was setting him up to be Khan'd.
