As per post-fight interview with both boxers, Diaz himself said that he could not keep up with Pacquiao’s speed. His promoter even joked that for the next fight, they will get a slower fighter for Diaz. While Diaz fought well and hard, Pacquiao always had more counterpunches each Diaz’ offense. Pacquiao himself said that Diaz was the most difficult fighter he had every fought with for being much stronger, forcing him to give him all he got from his arsenal. Pacquiao’s right jab has gotten more lethal as can be seen in the fight. Woot! Woot! You got him, Pacman!
Pacquiao’s coach-trainor Freddie Roach was right all along about his ward about ending the fight somewhere on the 8th-9th round. If it has gotten longer, the fight could’ve gotten ended differently as Diaz was known to get fiercer on the last rounds.
