Pipino Cuevas seemed to have an iron chin untill Hearns crushed him John Mugabi's chin was good up to the Hagler fight. After that it was pure glass McClellan took care of whatever Julian Jackson had for a chin There are many examples of fighters whose chin wouldn´t hold up anymore after taking brutal shots. This may or may not be the case with Pac. The future will tell us.
Hell yeah bro. As long as there are blind fanboys who can't accept that the objects of their man-love have china chins, and stubborn glass jaw deniers who think "that punch woulda KOd anybody," there will be a need for the Chincheckers here at ESB. Wake up ESB!!! GLASS JAWS EXIST in BOXING! And it looks like Manny Pacquiao has one.:yep
