Pacquiao is iron chinned and in more than 10 years has not shown being dazed by punches. Floyd barely ever gets hit so it hard to assess. He can be hurt though as shown by mosley and others. If floyds defense wasnt so great I think he woulda been stopped in his career.. still a solid chin
And Paccies 2 ko losses are easily explained. 1 livershot. (non issue, nobody has an iron liver) And the other KO loss was because he had extreme trouble making weight and he didn't belong in the division anymore, he was growing bigger and cutting too much weight is bad. floyd his chin does its job, he doesn't need a better chin. His defence does the job. Paccie does need the chin.
This is a good question. Honestly. This is going to sound really weird, but I can't recall pac getting caught or hit hard as he did against Marquez in any of his fights above 147. His fight against Mosley was a bad joke, mosley never landed or even throw, really, one loaded up right hand or left hook. For the first 3 rounds im uncertain what he was doing, he looked to just box and not be concerned with landing something that could end the fight. The fights where he took head shots was Clottely and Cotto. I think he took a few good shots from cotto in the first 4 rounds, well at least in the 4 or 3rd when cotto had him against the ropes. People talk badly about Pacs defense, but he always gets a bit of the punch on his gloves, i guess. I'd like to see how he wouldve taken those mosley rights Mayweather did. didnt get a chance to see it though.
Pac has better defense than people give him credit for, honestly. Think of the mosley fight, when did mosley ever actually land a HARD loaded up right, like he did with mayweather on Pac? 0. Cotto has power, but again he was not at his max weight, he said it took something out of him, I believe it could have as far as his pop goes. But he did land some good punches in round 4 of their fight, but pac often got a little of the punch with his high guard.
From what i can tell, they both have solid chins. I think people exaggerates when Floyd gets tag with a flush hit and makes it such a big deal as if it has done more damage then usual. Perfect example is why Corley hit floyd str8 on the button and Floyd had to hold for a bit everyone went nuts when they saw that thinking Corley was about to upset.
Manny Pacquaio has a better chin but I would be more shocked to see Floyd KOd than I would Manny Pacquaio.
Mayweather may have stronger or weaker, I can't tell, he has never been nailed like pac has. I like Pac and root for him if they fight, but Mayweather has impressive defense. I will say Pac does not have weak chin, he has been tested past few years, and has stood up well.
Floyd never gets hit, but when he does his chin shows it. He got floored by a range-seeking jab from Zab Judah, and the first decent shot from Shane Mosley made his legs go rubbery. Pacquiao got stopped once with a shot to the jaw, but we've also seen him take a lot of punishment from hard-hitters and take them very well.
