Hameds arrogance was his downfall. He did fulfil his potential imo as he was a unified world champ and recognised as THE man at 26. But he could have gone on to be an ATG. But by the time Suarez was training him all he and Naz`s backers did was blow smoke up his arse and inflate his ego even more. By the time he fought Barrera he really thought all he had to do was walk in there throw 1 big punch and put him to sleep. No one expected Barrera to come out and box and put on a fundamental clinic on the sweet science. Naz was dumfounded. His bubble burst as did his ego. But by that time he was comfortable, the richest featherweight of all time and simply didnt need or want boxing anymore. They only thing that went to waste was his phenomenal talent.
