It would have been a great fight, Tszyu was exceptionally good against southpaws and his punches had a paralyzing effect,his demolitions of Ruelas and Gonzalez are perfect examples of how Tszyu would break you down over rounds and just keep pounding away with incredible accuracy. I think Manny may have fallen victim to Tszyu over time, the Tszyu from 1998-2001 was an awesome force and i have no doubt had Hatton fought a younger, more active and less injury prone Tszyu then he would have been outta there by the 5th or 6th round. I think Tszyu like Marquez is a bad match up for Manny Pacquiao.
