Gamboa and Kirkland are the next to be Ko'd...I think Berto is too.

dont diss kirkland. when he gets out, williams is on the hit list

Kirkland? Gamboa? Berto? How can you say they have bad chins? They've been down, sure, but never seriously hurt. Their problem is poor defense. Dawson has shown a questionable chin though.

So for real answers...

Dawson
Dimentreko (If "chin" is a general term for punch resistance, anyway)
Valero (Okay it hasn't been tested, but how can you stick it out like that and expect it to take anything?)
Abregu
