I've thought that as well, I don't see many guys outside Hopkins and Roy Jones, and theoretically Thomas Hearns, being able to counter Calzaghe effectively, but these three are on the ball enough to catch the big mistakes Calzaghe makes in the ring that his speed and timing make up for against more opponents. Hopkins gave of us a glimpse at how are real fight between them would have gone, except like ICB said he would counter more, with harder shots, and he would also come forwards more. Prime Hopkins was similar to Calzaghe in that he liked to be in control of the fight, and would do what was necessary to get it.
