You have to be fairly hard to get in a ring in the first place (unless you are FMJ), but one guy that stands out above all the rest as being one hard son of a bitch is Marcos Maidana;
The guy even has a gun pointed to his never regions, that is how hard Marcos Maidana is!
What a fight Maidana vs Eddie Valero would have been. One bomb after another, South American pride at stake. Maidana would have won that as well imho.
A granite chin. A body so hard that he recovered from a brilliant body shot by Khan to last the 12 rounds, and a Hayemaker that could KO anyone in his weight division. If it wasn't for the Wizard Roach's magical superior will, Khan would have been another victim of Maidana.
I fear for Morales' life vs Maidana. One bomb and he could be seeing stars Hatton style.
I'd find a tattoo like that very distracting. Would that be a good thing?
