Morales should have made an arrangement with Barrera for them to unretire and do an exhibition match. Other than that I don't see any compelling reason for him to return to boxing. He already has a hall of fame career and, so far, the only boxer to have beaten Pacquiao while the later was at or near his peak. It will be a pity if he gets remembered as someone who was beaten up in a one-sided mismatch.
