Kirklands chin is hugely under rated, like him. He is the second coming of Chavez. I even heard the military have named bullet proof glass after him due to it's resilience which is similar to his chin.
Kirkland is good to watch, but lets put it in perspective, he's aggressive but has a shaky chin and a low IQ. Americans hate Khan, but really, they are damn similar just a different style in the ring, but they both cant really back up the style they want too
i'll always tune in to watch Kirkland knock someone out or get himself humbled again
