Horn is young and in his prime and will carry a significant size advantage in the ring. Pacquiao is 38 years old and half-shot and may not be able to pull the trigger anymore. I can't see him getting up for this fight, which is my biggest concern.
Jeff horn isn't even a Katsidis... Pacquaio is going to turn him into Katsu chicken, that's for sure.
Margarito and Algieri should have been TKO wins. Rios could have been TKO'd, but Pacquiao took his foot off the gas and didn't want to hurt him anymore.
Margarito though a cheater has always had a granite chin. That was always his best asset, there was no way Pac was going to knock him out..
Many boxers have fought with swelled eyes, it wasn't determined he had a broken socket until after the fight. It was justified not to stop it.
