Is there any instances that pbf showed he had a suspect chin?

I dont think Floyd has a suspect chin, but the pucnhes he took from Castillo were at light weight, from a lightweight,and yes he was a lightweight also which is fair, im not trying to bring Floyd down or anything just trying to put my two cents. After Castiilo from what i remember, the only good pucnhers he fought have been Gatti? Judah, and DLH. Gatti was outclassed, and that was at Jr.welter, Judah stunned him, but very few people who fight judah arent stunned, and DLH didnt really hurt him, and i think those may have been the heaviest punches Floyd has had to feel. So like i said in the beggining, i dont think Floyd has a suspect chin, infact he has a pretty strong neck and is always well conditioned, which are the things you are suppoused to have to improve your chin, and besides that, he rarely gets hit because of his terrific defense. I just think he hasnt been punched frequently enough by srong punchers, and thats where i think that Miguel Cotto could do a better job then most other fighter in the welter division, he is a good skilled fighter with the heavy fists. So although i dont think that Floyd has a suspect chin i do think it is breakable, im not saying Cotto stops him, but if he is able to keep landing through the fight, it could be a lot more thougher for Floyd than what he expected. well gotta go for now, God Bless people.

 

he showed against Castillo he can take a big punch.

also Oscar landed some big body shots and Floyd took em well

and Zab landed a few too.

He hasnt shown that its iron but its not suspect

 

When he fought hatton in the first round Floyd look very uncomterble i though he was gonna go down.

 

Floyd doesn't have a suspect chin ... he's been hit flush on the chin by bigger guys. He spars w/ super middle and light heavyweights ...
