Realisticly speaking he has had some great performances in the ring, performances that have semented a legacy as one of the greatest of all time. Most of his top performances were in his last few fights. It has to be between demolishing Hatton in two quick rounds, destroying ODH and sending him into retirement, or the destruction of Miguel Cotto. I would go with the Cotto fight because you can argue that oscar was washed up and Cotto was still on top of his game, and in my opinion outclassing and totally dominating one of the greatest fighters in the world today over the course of 12 one sided rounds is more inpressive than catching Hatton with a good one early.
