All I know is that fightérs' height is adjusted to be more or less close to his opponent every fight - to help hype up the fight )making it appear to be evenly matched).
Pictures can't be used, since either of them could be wearing shoes with thick soles. Furthermore, on each of the pictures presented at least one person is crouching slightly, or angled shots. Pictures of them standing side by side from the same perspective, and none of them crouching with boxing shoes on is the only way to be certain.
There is a reason why Calzaghe is considered the most versatille fighter in the world, he can adapt his height for fights against different opponents.
:rofl one of my favourite chj quotes, although the one he just posted in this thread is pretty superb as well.
