He messed up going to RJJ, so it's gonna be a tough comeback from this. He tried to fight like Roy, which is impossible. Even Roy couldn't fight like Roy when age started hitting him. He's lost muscle mass since going to RJJ. Besides the physical appearance, he also seems to have lost the explosiveness and killer instinct he had. I don't see a way back to world level personally. He's too old and the chin is most likely cracked. He might make some quick paydays from the rematch and maybe Con Benn down the line.
