I'm not sure this so called king of the chins thing should really even change as much as it does...i mean there are guys that can take a punch then there are guys who can take a bunch of punches. Margarito can definatly take a punch so can andrade but there are also others that move thier head and choose not to take as many punches but let's not keep them off the list because they make sure they don't get hit. Anyhow i like to throw rocky juarez out there i've never really seen that guy seriously hurt for as much as he gets hit. I'd say anyone who fights darchiniyan and doesn't wind up in the E.R. has a pretty good chin too.
