Why does Floyd Mayweather Jr. have a weak chin?

Question

If he has a weak chin then he should've been knocked out by Shane Mosley when he hit him! I've seen Manny get hit by Juan Manuel Marquez and he was staggered just like Floyd was, so does that mean Manny has a weak chin also? You're bias!! CHECK YOURSELF B4 YOU WRECK YOURSELF!!

Answer 1

I agree with you my friend. Nothing has happened in Mayweather's career to suggest he has a weak chin. All this potential fight has done is cause people to have factless arguements on the internet, its boring. Hopefully they just get on with it and end the madness.
