:yep In round 1 of a fight, his chin is glass, but as the rounds progress, his ability to absorb a shot certainly seems to improve. Beyond that, even with the shaky chin in the early rounds, Kirkland seems to have decent recuperative powers. That said, Kirkland-Mayweather makes very little sense to me for several reasons.
Floyd does better with boxers than brawlers like Mandingo. Mandingo would most likely try to walk thru Floyds shots, but I think Floyd would keep him humble, just outclass him. He's a beast , but too predictable for Floyd. Unless he had a decent jab, better defense, and better boxing IQ, I don't think Kirkland would do much. If you can't hurt Kirkland he can pressure you all night, even a hurt Kirkkand is dangerous, but Floyd will land ugly, nasty clean shots on Kirkland. This is one fight tho I don't think Floyd would want to go toe to toe with tho. Lol
